Some breast cancer treatments can bring on menopause more abruptly than it would happen otherwise. Again, this is called medical menopause if it’s caused by medicines such as chemotherapy, or surgical menopause if it’s caused by the removal of the ovaries. Medical menopause may be a temporary state that lasts while you’re in treatment and for some time afterward, or it can be permanent. Surgical menopause is always permanent.
With medical and surgical menopause, the ovaries stop functioning and hormone levels fall right away (surgical menopause) or over a period of weeks or months (medical menopause) — not over a few years, as usually happens with natural menopause. The suddenness of surgical menopause can cause intense symptoms for younger premenopausal women. Medical menopause tends to feel more similar to natural menopause. However, the experience really depends on the individual woman.
