Breast cancer is on the rise in women under 50. It could be linked to 2 lifestyle factors.
Briefly

Breast cancer deaths declined by 44% between 1989 and 2022, translating to 517,900 fewer deaths, largely due to earlier detection and advances in treatment.
Dr. Ahmedin Jemal called the increase in breast cancer cases among younger women 'concerning', but emphasized that the disease is often treatable and prevention is key.
Lifestyle factors such as not breastfeeding and having children later in life may be contributing to the rise of breast cancer cases in women under 50.
Although cases of breast cancer rose by 1% each year between 2012 and 2021, the absolute risk for young women remains low, at 6.5 per 100,000.
