A recent study published in The Lancet Public Health has shed light on the increasing rates of cancer among Generation X and millennials in the United States. The study identified 17 cancer types that are more prevalent in younger age groups compared to older generations.
Researchers analyzed data on over 23 million cancer patients and more than 7 million cancer-related deaths, focusing on adults aged 25 to 84 from the years 2000 to 2019. The study revealed a significant difference in cancer incidence rates and types across different generations, with certain cancers showing a notable increase among young adults.
Among the 17 identified cancer types with rising incidence rates in younger cohorts are uterine cancer, small intestine cancer, breast cancer, ovarian cancer, and pancreatic cancer. The study also highlighted a concerning trend of obesity-related cancers, such as colon, kidney, and gallbladder cancers, showing an increase among young adults.
Experts suggest that environmental factors or lifestyle changes may be contributing to the surge in cancer cases among young adults. Early exposure to certain risk factors could be a key factor in the development of cancer at a younger age.
On a positive note, the study found that cancers related to tobacco and HPV infections, such as lung cancer and cervical cancer, are on the decline in younger generations. This decline is attributed to factors like HPV vaccination and reduced smoking rates among younger individuals.
Dr. Hyuna Sung, the lead author of the study, emphasized the importance of understanding the unique social, economic, and environmental factors that influence cancer risk among different birth cohorts. While the study provides valuable insights into the changing landscape of cancer incidence, further research is needed to fully comprehend the reasons behind the rising rates of cancer among young adults.
