Other cancers, including breast, stomach, pancreatic, uterine, and prostate cancers, are also becoming more common in younger adults. Among adolescents and young adults aged 12 to 24, an average of 190 cancer cases were recorded annually between 2008 and 2017. Extending the age range to 29 raises the figure to 351 cases, almost one new diagnosis every day. Researchers link the trend to lifestyle factors such as diet, obesity, and low activity levels, along with improved detection and screening.
