The Daily - Why Adults Are Getting Cancer at a Younger Age

Episode Date: August 10, 2026

For years, cancer has been seen as a disease people mostly get when they’re older. That seems to be changing as more young people are getting cancer than ever before. Today, Nina Agrawal, a health reporter for The New York Times, explains what scientists are learning about the factors driving the rise and what it means for a generation of young cancer survivors. Guest: Nina Agrawal, a health reporter for The New York Times. Background reading:  Hundreds of New York Times readers shared their experiences with early-onset cancers. Here are seven of their stories. Research is starting to offer clues about why more than a dozen types of cancer have increased among people under 50 in the past decade.

From the New York Times, I'm Rachel Abrams, and this is the Daily. You go into the chemotherapy room, and I remember sitting in a circle with like 60 to 80-year-olds, and I'm there as a 25-year-old. For years now, cancer's been seen as a disease that people mostly get when they're older. But apparently, that's changing. When I was diagnosed, I was 28. Yeah, I was 32. When I was 37. More young people are getting cancer than they ever have before.

I wasn't able to be the kind of husband that I wanted to be, the kind of father that I wanted to be. Dating was like a new challenge for sure. I mean, I had to file for bankruptcy. I ended up having to do chemo while I was pregnant. At a time when you really feel like you have so much in control on your life, you're just like you completely lose control of everything. And so today, health reporter Nina Agarwal explains what scientists are starting to learn about what's driving this rise. and what it means for a generation of young cancer survivors. It's Monday, August 10th.

Nina Agarwal, welcome to The Daily. Hi, thanks for having me. Nina, your beat is chronic disease, and you recently published a series on the growing rates of cancer among young people, and we're going to talk about what you found in your reporting. But before we do that, I just want to define what we're talking about here exactly.

Like, who and what are we referring to when we talk about growing rates of cancer among young people? So early onset cancer generally means cancer in adults under 50. So not super young, but young for cancer. Cancer has historically been a disease of aging, but researchers have started to document in a pretty systematic way that cancer diagnoses are increasing in younger adults. And this is something, you know, we've been hearing about kind of in trickles, but, you know, in the last couple of years, there have been some comprehensive papers showing that this isn't just an isolated phenomenon. This is a pattern happening across cancers over decades, and it's been happening

every year since 1990. And, you know, the rates vary from cancer to cancer. So for some, it's annual increases of 1 to 2 percent a year. And for others, and in certain age groups, the increase could be as much as like 6% per year. Wow. So you can imagine that over time that is like quite an increase for certain types of cancers, as you said. Yes. And for younger people, it's very unexpected. I mean, I think a cancer diagnosis is unexpected and undesired at any time, but it comes out of left field for so many of these younger adults. And it totally upends their lives in a way that is different from the way it upends the lives of older people. because this is happening at a really vital moment in their life,

when they're still kind of putting down the roots and becoming the adults that they're going to be. And I spent a good part of the last year trying to understand exactly what the experience is like, not only what's happening and why, but what that means for the people who are getting diagnosed. We had hundreds of people right into us to share their experience of early onset cancer,

and I spoke to dozens over months to just get a picture of all of the ways that getting a cancer diagnosis in that time of life, your 20s, your 30s, your 40s, how it changes a trajectory of everything that comes after. I wonder out of all the people that you spoke with who are dealing with these issues at such a young age, is there somebody who stands out to you specifically that maybe illustrates some of what you're describing? Yeah, I mean, there were so many whose stories were really moving. And there were some common themes among many of you. the stories in terms of disruptions to their finances, disruptions to their family planning, disruptions to their careers, disruptions to their relationships. But one young woman I spoke with Whitney Johnson, her experience and her story really stuck with me. Tell me a little bit about yourself, what your life was like before you got cancer? Yeah, so I, Whitney Johnson. So she was 36 and living in Portland, Oregon. And she was just, you know, at a stage where a lot of people are in

their 30s. Trying to focus on my career, trying to focus on, like, redoing my house, trying to figure out if my boyfriend and I should stay together. She was in a relationship that was relatively new and trying to figure out where she was with her boyfriend and kind of where it was going. And one night, about two and a half years ago, they were making out. We started kissing and kind of stopped at one point, and he's like, I don't want to be weird, but I think I feel something in your boop.

And that's how she found the lump. Oh, my God. That must have been so jarring to have him say that in the middle of this, like, very intimate moment. What was your diagnosis? Triple negative breast cancer, stage 2B. And so that means that the tumor was, I want to say, around two to three centimeters. Yeah. She was diagnosed with triple negative breast cancer, which was a pretty serious and aggressive type.

And when she got the diagnosis, she not only had. the tumor in her breast, but also some signs of cancer in one of her lymph nodes. At that time, she had just gotten back from a family trip and vacation, and she ended up not going back to work because she needed to go into treatment immediately. What did that treatment look like? So she was going to need chemotherapy and then also at least one surgery. But before she could even start, doctors asked her if she wanted to freeze her eggs. And so first things first, like my brain wasn't even on the cancer.

my brain was like all the things that go into freezing your eggs and what that meant for like my future and what that meant. Like my boyfriend and I at that time, like we weren't talking about having kids. You know, she and her boyfriend had been dating a couple of years at that point. And all of a sudden she had to think about, you know, is this something that I'm going to want, that we're going to want? And she's over the course of a few weeks having to inject herself with hormones and he's trying to be supportive, but they were not in a place in their relationship where they were

both trying to do this of their own volition. And so it's just kind of a wild start to the whole situation. That feels like so much pressure at the sort of newer end of a relationship when, as you said, they're not even talking about having kids because they aren't even on the radar. And just to say, egg freezing is a really intense process. It's intense emotionally and it's also intense physically. Yeah, absolutely. And the whole experience of having cancer,

and having then to go through treatment was upending her notions of what it was to be a woman in this relationship. One of the reasons I was really moved and struck by Whitney's story was she talked very articulately about being a woman in this phase of life. As women, like, we spend her whole lives trying to figure out, like, how can I show up in a way that feels right for me, and I can feel confident and, like, I can love who I am. Like, she talked about how it had taken a long time, you know, to grow into herself. And she loved her hair. That was one of her defining features. It was like long and blonde and beautiful. And she'd come to like her breasts.

That hadn't always been the case. But at this point, she was really comfortable with herself. And then here she is, and she's going to get chemo, and it's going to make her lose all her hair. And she's going to have a bilateral mastectomy, and she's going to lose her boobs. And then even if I do get through this, you're telling me that I want to try to date someone

when I don't have hair and don't have boobs and don't have estrogen. And it just totally shook her notions of being like a sexy, confident woman when she was also kind of early in this relationship where that's how she wanted to show up in that relationship. Like it's just like this perfect storm of stealing your femininity when you're supposed to be feeling kind of like at your height of womanhood in some ways. And so it's pretty fucked. I'm curious how her boyfriend navigated all of this because this is just

so much pressure, obviously, to put on a relationship that is relatively new where you have two people who are still trying to figure out what they want, they're still trying to get to know each other. So to have this giant tragedy dropped in the middle of that, I can imagine why that is a different dynamic than when this happens to a couple that is established for many, many years

and just has a different familiarity with each other. Yeah, I mean, one of the things that she said was like, we had no practice. You know, like, we didn't have peers and friends who were in this situation, and his friends didn't really know how to support him, and all of a sudden, he's thrust into this role of being caretaker. He was, like, 29, I think, when she was diagnosed. And then I remember there was this one weekend that he was out with his friends. And that was the weekend I realized I might die. She told me one story about how she was at a really low point in her treatment when she was really sick. And she was.

She sort of had this realization, like, oh, I might die. Because, like, you know, you always kind of know, but you don't ask directly. And then I'm like, oh, this might be 50-50 that I'm here in five years. And I think it was the first time that I had let myself think about it. Like, this might be it. She was kind of just spiraling, and her boyfriend was out at a cabin that weekend with friends. I remember, like, I was trying to process this. and then, like, you know, texting,

but he's, like, at a cabin partying with his friends. But I'm like, I need to talk. And I'm like, I might die. Like, talk to me about that. But, like, he couldn't. He's like, I'm here with my friends. I need a break. I don't have it in me.

And that was terrible. They're like, I'm at my darkest, and I want my partner to see me through this time. and he just couldn't. And she needed him in a way that their relationship kind of hadn't experienced before and maybe wasn't ready for. God, that sounds so tough for both of them. Yeah, definitely for both of them.

I mean, she told me, I don't think it's easy to get cancer at any age, but that she was jealous of people who got it when they're older because maybe where they are in their relationship can withstand it a little better. Everything was one-sided for a long time. And we weren't there, and it didn't go well. Did they consider breaking up, Nina? I asked her, and she said, you know, she was really just like in survival mode,

like trying to deal with cancer, and it felt like thinking about her relationship ending was just like too much to think about taking on. That would make my head explode. when that was the sort of support, and she was just trying to get through the day-to-day of fighting the cancer. What about her friends? Did she have friends that were part of a support system? Not just her boyfriend? She did, but her family didn't live in Oregon, and her friends were in a similar stage of life as she was before the cancer. Some of them were getting married and having babies, and, you know, it was hard to be around people whose lives were moving forward.

And this is something many people told me. It was really hard to watch their friends and their peers and their colleagues move forward in their lives, and you're just sort of stuck or maybe even moving backward. I remember the walk I went on a friend with. She told me about how she had gone for a walk with a friend, and her friend told her that she had just gotten pregnant. And she could see that the friend was having a hard time sharing this with her. And it was one of those moments that, like, I feel so bad because she was sad to tell me. because she knew it would be hard. But, you know, it was sad to see her friend moving forward in this way,

and she was having to put this pause on everything. And so, you know, your friends are who you, if you spend your time with, you kind of compare yourself against. And so they're, like, able to be taking these next steps in their lives. And as I'm, like, taking a step back into nothingness and the unknown. So how did Whitney's treatment go? So it was grueling. She completed her chemotherapy, you know, lost all her hair.

She had a double mastectomy. For now, the cancer's gone, but that doesn't necessarily mean it's gone forever, and a fear of recurrence is real. And I think Whitney's still dealing with how unexpected this cancer diagnosis was at this time in her life and kind of grappling with why it happened at such a young age. You know, and that's something I've also been really interested in. reporting on what scientists are learning about what's driving these rates of early onset cancer. And scientists are starting to find some answers. We'll be right back. Nina, I want to better understand what we understand about what's driving this increase in cancers.

So maybe just to start, can you lay out when we say that cancer diagnoses and young people are rising? Which cancer specifically are we talking about? So there are a number of cancers that appear to be increasing in the, earlier age group. One paper from last year showed that 14 different types of cancer were increasing in the early onset age group, and that includes some common ones like breast and colorectal cancer, as well as uterine cancer, testicular cancer, pancreatic cancer, and several others. And just to ask a question that I'm sure is on a lot of people's minds listening to this, these increases cannot just be attributed to increased screening.

No, I mean, depending on the cancer, some might be attributable to increase screening. like thyroid cancer is one that comes to mind. But for a number of reasons, a lot of experts I talk to said they don't think it's all screening or incidental diagnosis. For one, most of these cancers, when we're talking about people under 40 or under 50, these are not populations that are regularly screened. For another, you know, some of the cancers certainly are showing not just increased incidents, which could be they're just finding them, but also increased mortality. And that's particularly true for colon cancer and uterine cancer. And something else that we're seeing is that people born in more recent generations are at greater risk of having cancer, which suggests that there

might be environmental or lifestyle exposures, things that have collectively happened to us as a society over time that could be affecting our cancer risk. Well, let's talk about that a little bit more because I'd like to understand what we do know about what is driving these upticks. So talk to us a little bit about those environmental factors and how they're interacting with our biology in a way that may be contributing to these trends. Sure. So I will say because the phenomenon has really pretty recently been identified, researchers don't know for sure what's driving it. But they have some hypotheses and, you know, they're building off of what we know about what causes cancer generally. So there's a fair amount of evidence linking obesity, alcohol use and poor diet, particularly

red meat and ultra-processed foods to some early onset cancers. And then there are other questions that researchers have about potential other exposures like plastics or forever chemicals. But it's really hard to tell at this stage because it's very hard to link things in our environment directly to a cancer outcome. One of the most classic examples of this is smoking. It took researchers a long time to link smoking to lung cancer. But eventually there was such a large body of evidence that they could make that causal link. Right. Cancer is notoriously difficult to prove causal links to, whether it's where you live or what you're eating.

Yeah, but some of the more emerging evidence is showing some surprising things as well that suggests the drivers of earlier onset cancer are different from some of the things we've historically thought about. Tell us about some of those surprising findings. One of the things that researchers are really trying to look into is how our environment or things in our lifestyle might be affecting our genes. So it's unlikely that as a population, our genome has changed dramatically in the last 50 years to make us as a population more susceptible to cancer. Right. So one area that researchers are looking into is how things in our environment might be affecting our genes, once we're already alive, to maybe make us more predisposed to cancer. Like what? So one example is in colorectal cancer.

You know, I spoke to a researcher who's been doing some work. analyzing the pattern of mutations in patients who had early onset colorectal cancer. Mutations in their genome. Right, exactly. Changes to their genes. And he's able to see a sign of an E. coli infection with a particular kind of E. coli in the pattern of mutations in the patients who had early onset cancer. And he also was able to say that the E. coli infection had likely happened pretty early in life,

like within the first few years. Meaning what? that these patients showed signs that they had gotten infected with E. coli when they were that young. And so he's now making some sort of a connection between E. coli and colorectal cancer. I mean, that's a big leap because you can't infer causality. But because you're getting this hit to your gene within the first few years of life, and then that mutation is going to be compounded by other mutations or by factors maybe like inflammation, you're sort of getting put on the fast-track to cancer. And that might be one explanation for earlier onset cancer. But, you know,

that being said, we don't necessarily know. And I asked, you know, have we been as a society having more E. coli infections over time? That would be my question. Are we getting exposed to E. coli more and more? So I think some researchers are trying to look at samples that were biobanked decades ago and see if they can track E. coli in the samples over time. I don't think that research has been done yet. But the researcher I spoke to did tell me something interesting, which was that there are some suggestions that the particular type of E. coli that may be creating this set of mutations has come with industrialization. So it's kind of like a hand-wavy way to say, maybe it's something in the food that we now eat or the antibiotics we use. They don't really know, but they are seeing

this link. Even if we don't fully understand it, there's some connective tissue there is what you're saying. Yes. What about some of the other cancers you mentioned, Nina? Do we know more about what is driving those, what's contributing to the upticks there? Yeah. So researchers have also done a fair amount of work on breast cancer and are also looking at this interplay between our environment and lifestyle and how that might be increasing our predisposition to cancer. And so one of the things that they've found is the role that the menstrual cycle and how much that's, you know, how much many menstrual cycles we have might be playing here because some research has shown that girls now get their periods a little bit earlier than they did in the 1950s and women are having

their first pregnancy later than they did in the 1950s. And the menstrual cycle is this time where your cells are expanding and proliferating and your hormone levels rise and fall. And as the cells are dividing, they're more susceptible to mutations. And so during that time, if you're exposed to something that's harmful, like alcohol or something that can increase your risk of a DNA mutation, the effects of that can accumulate the longer you have this time period where you're kind of going through these monthly cycles of cell proliferation, expansion, and then dying off. And pregnancy kind of stops that prolonged period of increased risk because there's something protective of. about a first pregnancy, particularly at a younger age, and breastfeeding. After that, in the long run, your breast cells, they spend more time doing DNA repair, and they've sort of changed in a way that is protective against breast cancer.

So basically this combination of women getting their periods earlier in life, and also having children later in life, is expanding that in-between period where they are most vulnerable to breast cancer. Is that right? Yeah, or most vulnerable to the changes that can lead to breast cancer. I'm also hearing by implication, I think, something that feels a little shocking, which is that women who don't have kids, whether it because they can't or they don't want to or whatever the reason, they are more vulnerable to breast cancer? Is that the right inference to be drawing from this? Yeah, it's totally crazy and unfair.

And I know that that can just sound like we're blaming women for their own cancers, which is not at all what researchers say. they're saying these are societal shifts. And it's totally reasonable in this day and age that women want to have a career or not have a baby at age 20. But at the population level when they look at kind of what are the factors that are linked, they do find that pregnancy, particularly a first pregnancy at a younger age, between kind of the ages of 20 to 25 and breastfeeding are protective against breast cancer in the long run. What you have laid out, some of these findings are really genuinely surprising, I think a lot of people know by now that toxins like alcohol and smoking may contribute.

But the thing you said about pregnancy, the idea that there's bacteria hanging out in your gut from when you're a kid that could cause cancer or could lead to cancer or somebody, I don't think that those are factors that are really on people's minds. Yeah. And I think people want to know if there's a reason for their cancer. But I talk to so many people who were diagnosed with early onset cancer. And it's so out of their control. Like there are lots of people who ate their vegetables and had a good diet and exercised and had babies pretty young and still got breast cancer. I've talked to patients in that situation. It feels like it's worth saying that even if we start understanding more and more about why younger people are getting cancer, getting that kind of clarity is not necessarily going to be total comfort for people who are sick.

They're not going to know exactly for sure what caused their cancer. That's just not how science works. and that's probably going to just be very unsatisfying, even if we are more educated. Yeah, I think for most people, they'll never know exactly why they got cancer. Nina, I want to go back to Whitney for a second because you said her initial cancer diagnosis was two years ago.

How was she doing now? The last time I spoke with her, she was doing pretty well. She had gone back to work, and she and her boyfriend were moving in together, but she was still kind of dealing with the emotional and physical scars of this experience. I think that's going to take a lot longer to do.

For example, after her double mastectomy, she did eventually have a reconstruction. Having this reconstruction, it's been one of the hardest, like, lasting parts. She's had people say to her, like, oh, you know, you got your boobs done, and she's, like, totally just incensed by that comment because she's like,

do you understand that a mastectomy? This is not a walk in the park. This is not something I wanted. And even though her reconstruction was successful by standards of the surgery. I hate them. I hate them a lot. She kind of hates her new breasts,

and they don't feel like hers, and it's a hard line for her to tow, much less her boyfriend. Because, like, you're not supposed to like these better than the old ones. You're supposed to like the old ones better. But yeah, you're supposed to support the new ones and love the new ones and think they're beautiful.

So she, you know, on her good days, can be sort of accepting of what she looks like and who she is now, and on her bad days, there's a mix of trying to move forward. and also grieving what was or what could have been. And she's trying to figure out what's next for her in her life. She's wondering whether she wants to have children, and if so, you know, maybe soon.

She's, of course, worried about the cancer coming back. But really the thing that sticks with me the most about her was just how lonely the experience was and also how unprepared she felt for it because it's not something that typically happens in this stage of life. And I think that was true for most of the people I talked to. One of the things they wanted people to understand

was this isn't just like a temporary derailment and then you go back to your normal life. And because this phenomenon is relatively new in the sense that researchers are able to see bigger picture trends and documented and talk about it. People who have been diagnosed at a younger age don't really feel like the public

or even their friends and family get what they're going through. People want to help you, but also they might be really bad at it. You're so totally alone and really are in charge of yourself. And I think a lot of the people I spoke to

really wanted to speak to me and tell their story because they wanted other people like them to feel scene. Nina Agrawal, thank you so much. Thanks for having me. We'll be right back.

Here's what else you need to know today. On Sunday, the Israeli government rejected President Trump's plan for rebuilding Gaza. The 15-point proposal included the gradual disarming of Hamas and the withdrawal of the Israeli army for more than half of the area that it still controls. But Prime Minister Benjamin Netanyahu dismissed the phased approach, saying that Israel won't leave Gaza until Hamas is completely disarmed.
