Some women can and do become pregnant after breast cancer, and recent studies suggest that pregnancy after breast cancer should not increase your risk of recurrence. However, you should consult your doctor before attempting to get pregnant. It is important to realize that certain cancer treatments can affect one's ability to bear children, and careful thought and planning is necessary to preserve fertility before and during treatment.There are some clinical issues to consider when thinking about pregnancy after breast cancer:Impact of chemotherapy on ovaries – At birth, every woman is born with a full complement of eggs in her ovaries to last a lifetime, expending one each month with her menstrual cycle. However, chemotherapy can damage ovaries in a variety of ways. Even if you didn't experience menopause, chemotherapy may kill some eggs completely, or may have damaged your remaining eggs, so they may be incapable of fertilization or may cause genetic defects. Consult a fertility specialist to determine the quality of your eggs and whether you have a chance at a successful pregnancy.Year of survival – While there is some debate, some oncologists recommend that you wait until you are past your five-year survival mark to consider pregnancy due to the impact it may have on your body. Others recommend waiting only two years.Extended treatment – Some women require additional hormonal therapy after treatment, such as 5-10 years of Tamoxifen, which can further delay pregnancy. Speak with your doctor about the possibility of taking a break from Tamoxifen to have children.
