80% of Young Cancer Survivors Report Sexual Dysfunction

A cancer diagnosis in your twenties or thirties rearranges nearly everything. School, work, dating, the vague plan for a family someday. According to research presented at the APOS 2026 conference, it also rearranges people's sex lives, more drastically than many clinicians assumed. Chiara Acquati, who holds the Beatrice "Bean" E. Robinson Endowed Chair in Clinical Sexual Health at the University of Minnesota, told CancerNetwork that over eighty percent of young cancer survivors experience sexual dysfunction, with sexual interest and arousal affected most. Survivors in her study also reported a sharp drop in sexual functioning compared with their own pre-diagnosis levels, and their scores came in below those of healthy peers on both functioning and satisfaction.

That timing matters. Adolescence and young adulthood are the years most people build their sexual identity, first relationships, and long-term bonds, as Oncology Nursing News noted in its coverage of the same research. A cancer diagnosis in that window derails that development, and the effects can linger long after treatment ends, shaping body image, confidence, and partnerships for years. Sexual health after cancer is a quality-of-life issue, not a footnote to survival. Young cancer survivors consistently say nobody warned them it was coming.

What the research actually measured

Acquati's team compared 174 survivors, all diagnosed between eighteen and thirty-nine, with 348 healthy volunteers matched on age, sex, and relationship status, according to Oncology Nursing News. Everyone completed two validated self-report measures, the Medical Outcomes Study Sexual Functioning Scale and the Global Measure of Sexual Satisfaction. Survivors reported significantly worse sexual function than their own remembered pre-diagnosis levels. The steepest declines appeared among female survivors and among those not currently in partnered sexual activity. Outcomes were also worse for people diagnosed in their thirties, for those who stayed with the same partner through treatment, and for those earlier in survivorship. For young cancer survivors, in other words, the damage was deepest exactly when life was supposed to be getting started.

Where survivorship care falls short

The need is large and the response is small. Acquati told CancerNetwork that 60% of young cancer survivors have unmet sexual health care needs. That figure captures something survivors live every day: survivorship care rarely makes room for this part of life. A separate study published in Supportive Care in Cancer on October 7 reached a similar conclusion for gynecologic cancer survivors, as reported by Newsy Today. Clinicians interviewed for that research agreed that sexual health matters for quality of life, yet the conversations happened reactively instead of routinely. Time pressure, provider discomfort, and assumptions based on a patient's age kept the topic off the table at standard oncology visits, and doctors often waited for patients to raise it first, which most patients will not do.

For young cancer survivors, the silence carries extra weight. Cancer in early adulthood collides with the years when dating, sexual exploration, and partnership are most active, and when asking an awkward question at a follow-up appointment feels hardest. Body image plays into it as well. According to our earlier reporting, distress about the body can spill directly into the bedroom for young men dealing with muscle dysmorphia. Treatment ends, but the sexual side effects often keep going.

Early signs of practical help

A pilot study from the University of Chicago points to one possible way forward for young cancer survivors. Researcher Ilayna Mehrtens tested a web-based sexual education program called OMGYes.com with female survivors of adolescent and young adult cancers, according to Oncology Nursing News. The starting group was small, thirteen cisgender women between eighteen and forty-five, most of them leukemia or lymphoma survivors. Their baseline answers were stark. More than nine in ten reported at least one sexual health issue after treatment. Over eight in ten said cancer therapy had left their bodies feeling damaged. More than three-quarters reported significant distress about the challenges that followed.

Early results from the program were encouraging. Every participant who completed the first modules rated it feasible, acceptable, and appropriate, and average scores on the Amsterdam Sexual Pleasure Index rose from just over four to nearly five, a statistically significant improvement. The sample is tiny and the data are still being collected, so this is a hint rather than an answer. Still, the direction is promising. A private, self-paced online tool may reach young cancer survivors who would never raise the subject in a clinic.

The larger takeaway is simpler than any single program. Sexual dysfunction after cancer is common, measurable, and not something survivors have to accept as the price of staying alive. Acquati's findings make the case for building sexual health checks into routine survivorship care, the way follow-up scans and blood work already are. For young cancer survivors navigating survivorship now, the evidence points to the same first step. Bring it up. The data say you are far from the only one dealing with it.
