Menarche, Menopause, And Breast Cancer Risk

Menarche, Menopause, And Breast Cancer Risk

Do early Menarche and late Menopause increase the risk of Breast Cancer?

Yes, to the longer duration of exposure to oestrogen. During women's reproductive years (broadly the time between menarche and menopause) the ovary produces steroid hormones that directly affect development and function of the breast. Early menarche and late menopause are known to increase women's risk of developing breast cancer.
