Cancer is rising in younger adults, and scientists can't fully explain why
A study of cancer incidence in England reveals a concerning rise in various cancers among adults under 50, particularly bowel and ovarian cancers. While obesity is a factor, researchers note that it does not fully explain the trend, suggesting other lifestyle or environmental factors are at play.
Why it matters
The shift in cancer demographics toward younger populations poses a significant challenge to public health policy and requires further investigation into modern risk factors.
Cancer rates are increasing among adults of different ages in England, but a new study has uncovered a particularly concerning pattern among younger people. Rates of bowel and ovarian cancer have risen among younger adults (under 50), while the same increases have not been observed in older age groups.
The findings, published in the open-access journal BMJ Oncology , also show that several other cancers are becoming more common at a faster pace among younger adults than among those aged 50 and older.
Although excess body weight appears to play an important role, researchers say obesity alone cannot account for the increases. The findings suggest that additional factors may be contributing to the growing burden of cancer in younger generations.
