Question:

why are women who have reached menopause more likely to get breast cancer.

Answer:

The age specific incidence of breast cancer in the United States shows progressive rise with age but a slight decline after the age of 75. The age of highest incidence is 60-65 years. Approximately 1/4 of breast cancer cases occur in women younger than 50. There is a rapid climb during the reproductive years after age 30 but a slower continued rise during menopausal years. It has been interpreted that premenopausal breast cancer is related to a change in ovarian hormones, whereas, adrenal hormonal predominance is related to breast cancer in menopause. The exact reason is difficult to pinpoint. It may be an interaction of many factors such as environment, diet, exposure to mammary carcinogens, changes in the immune system, differences in life style, hormonal, family history, all combined with rising age.
The key message I can give you and any other reader is to follow the American Cancer Society guidelines for early detection. Women over the age of 40 should have a mammogram and a professional breast examination every year. Breast self exams every month are more important than ever as women reach menopause. Regular screening has been shown to be effective in detecting early breast cancer. Early detection means more effective treatment and possible cure. Thank you for writing.
