A study conducted by American Cancer Society researchers found that the risk of developing various types of cancers, including breast, pancreatic, ovarian, and colorectal cancer, has increased among millennials compared to older generations. The analysis, which included data from over 23 million cancer patients diagnosed with 34 common types of cancer, revealed that the rates of 17 different types of cancer were up to three times higher in the younger generation than in baby boomers. Dr. William Dahut, the chief scientific officer at the ACS, attributed this increase to factors such as obesity, lack of exercise, and unhealthy diets, which likely began affecting individuals during their teenage and childhood years.
The study also found that age-adjusted rates of certain cancers, such as those in the small intestine, kidneys, and pancreas, were two to three times higher in the younger generation than in older generations. Additionally, there were smaller but still significant increases in other cancers, such as ovarian and uterine cancer, among millennials. It was noted that nine out of the 17 types of cancer that showed increases had previously been declining in older generations. Researchers hope that these findings will raise awareness among younger individuals about the risk of developing cancer and encourage them to be proactive about their health.
Jiyoung Ahn, an associate director at the NYU Langone Perlmutter Cancer Center, described the new findings as both alarming and surprising. There has been a growing concern among specialists about the rising rates of cancer among individuals under the age of 50, particularly in cases of colorectal cancer. The study provides concrete evidence that early-onset cancers are indeed increasing, with environmental factors such as obesity playing a significant role. Changes in the microbiome due to antibiotic use may also contribute to the rise in cancer rates among younger individuals.
Dr. Deborah Doroshow, a cancer specialist and associate professor at the Icahn School of Medicine, highlighted the concerning nature of the study’s findings. Not only are numerous types of cancer increasing in younger cohorts, but some of these cancers are also more challenging to treat. Screening for certain cancers, such as uterine and pancreatic cancer, is currently not possible, leading to later-stage diagnoses. These results underscore the importance of making lifestyle changes early in life, as prevention is crucial in reducing the risk of developing cancer, particularly for individuals in high school or college.
Dr. Alfred Neugut, a professor at Columbia University’s Mailman School of Public Health, emphasized the need for lifestyle changes to address the rising cancer rates among millennials. Neugut stressed the importance of focusing on teenagers and young adults to promote physical activity and healthy habits. Implementing changes at a younger age is crucial, as waiting until middle age may be too late to effectively reduce the risk of developing cancer. Overall, the study serves as a wake-up call for individuals of all ages to prioritize their health and take proactive measures to reduce the risk of cancer through lifestyle modifications.
