Scientists found that teens and young adults who survive cancer age more quickly than others their same age. This can lead to memory problems, attention issues, and difficulty processing information.

Cancer survivors in their teenage years or early twenties seem to age faster than people the same age who have never had cancer. Researchers discovered signs of this accelerated aging both inside cells and in brain performance. The study was published in Nature Communications and led by AnnaLynn Williams, PhD, from the University of Rochester Wilmot Cancer Institute, along with co-corresponding author Kevin Krull, PhD, from St. Jude Children's Research Hospital.

The research found that young cancer survivors may face not only physical aging but also cognitive challenges like memory problems, attention issues, and difficulty processing information. This can make it harder for them to reach milestones such as finishing school, launching careers, or starting families.

The study included around 1,400 participants who had been treated at St. Jude. Most of them had survived childhood cancer, with some having received chemotherapy or radiation therapy. The researchers found that survivors who had undergone chemotherapy experienced the greatest acceleration in aging.

The investigators also discovered a strong link between biological age and brain function. Survivors whose biological age was higher than their actual chronological age struggled more with memory and attention tasks. For those who had received radiation directly to the brain, preventing further decline became a priority.

There may be good news ahead. Ongoing work at Wilmot suggests that some of the accelerated aging seen in young survivors could potentially be slowed or even reversed through healthy habits like quitting smoking, exercising regularly, and improving diet.

Many cancer survivors are working toward finishing school, launching careers, gaining independence, or starting families. Cognitive challenges can make those milestones harder to reach. 'It's kind of like a perfect storm,' Williams said. 'This is why we see many survivors having worse educational and employment outcomes than their siblings.'
