The Who, What, Where, When and Sometimes, Why.

Having Children After Breast Cancer


Young women being treated for breast cancer may be concerned about loss of fertility (the ability to have a natural pregnancy).

Both chemotherapy and hormone therapy can impact fertility and shorten the window of time to have children.

Preserving fertility

There are steps women can take to help preserve fertility.

If you wish to have a child after breast cancer treatment, talk with your health care provider (and if possible, a fertility specialist) before making treatment decisions and discuss your options.

Meeting with a fertility specialist as early as possible (before surgery) offers the widest range of options.

Options may include storing eggs before treatment begins or using a drug during therapy to help protect the ovaries from damage.

Pregnancy and breast cancer survival

Having a child after breast cancer treatment does not appear to lower a woman’s chances for long-term survival [91-94].

Your health care provider or a fertility specialist can discuss the best timing of a pregnancy for you based on your breast cancer treatment.

Some treatments for breast cancer can impact your ability to breastfeed.

If you had surgery to only one breast, breastfeeding from your untreated (opposite) breast should be fine.

Breastfeeding should be avoided while being treated with radiation therapy, chemotherapy, hormone therapy or HER2-targeted therapy.

After lumpectomy and radiation therapy

Breastfeeding from the treated breast after a lumpectomy plus radiation therapy may be difficult. Both the surgery and the radiation therapy can harm the tissue needed for breastfeeding.

While feeding from the treated breast is possible (and the milk is safe for the baby), it’s not common and the amount of milk produced may be greatly reduced [95].

Other concerns about having a child after breast cancer treatment

Pregnancy after breast cancer treatment doesn’t appear to lower survival, but some women may have other concerns about having a child.

Women who have a strong family history of breast cancer may worry about passing on an inherited gene mutation that increases risk.

Women with a high risk of breast cancer recurrence may worry about having a recurrence while pregnant, or they may worry, like women with metastatic breast cancer, about not living long enough to raise a child.

Having a child is a personal decision. However, if you have any concerns, it may be helpful to talk with your health care provider or a counselor and to seek support from your family, friends and other loved ones.

Support for young breast cancer survivors and their families

Young women with breast cancer can feel isolated. Because most women with breast cancer are older, it’s easy to feel alone, even among other women with breast cancer. A support group tailored to younger women with any type of cancer may be more helpful than one for women with breast cancer.

Younger women need to be able to share their thoughts and feelings with women who are at the same stage of life and may have similar concerns about fertility and having children.
