The short explanation
Chemotherapy can damage the ovaries, and for some women periods stop permanently afterwards. When this happens before forty, it is a form of premature menopause. Sometimes periods return months or even a couple of years later, especially in younger women, so it is not always permanent. Low oestrogen at a young age can cause hot flushes, vaginal dryness, mood changes and, over time, a higher risk of bone thinning and heart disease. Your doctors will weigh the right way to manage this alongside your cancer history.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Whether hormone treatment is suitable depends on the type of cancer you had. For some cancers, such as hormone-sensitive breast cancer, hormones are usually avoided and non-hormonal options are used instead.
- Even if periods have stopped, pregnancy may still be possible in some cases, so ask about contraception if needed.
- Bone health checks, such as a bone density scan, are often suggested. Talking to a counsellor can help with the emotional impact of cancer and early menopause together.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This answer cannot tell whether your menopause is permanent or which treatment is safe for you. Your oncologist and gynaecologist will decide together.
