Some treatments for breast cancer can affect a woman’s ability to become pregnant. Once treatment for breast cancer has finished there’s no reliable test to find out if a woman can still become pregnant.
If a woman’s periods stop for a year or more, it’s likely that menopause will be permanent. If menopause is permanent, it’s not possible to have children naturally.
If a woman does fall pregnant after treatment for breast cancer, there’s no evidence that this will increase the risk of breast cancer coming back.
If you have been diagnosed with breast cancer and you were planning to have children before your diagnosis, speak to your oncologist before starting treatment for breast cancer. It may be possible to see a fertility specialist to discuss the available options.
