Preventative Mastectomy & Pregnancy

With the improvement in screening and genetic testing options, women are finding out at much younger ages that they might have an increased risk of developing breast cancer. With this earlier awareness also comes a wave of women looking into prophylactic mastectomy options to prevent cancer before it can develop. 

But what does this mean for women in their childbearing years who are also at risk of developing breast cancer? Does getting a prophylactic mastectomy affect their journey to motherhood? Or does pregnancy have an impact on mastectomy and reconstruction results? For women wondering about getting a preventative mastectomy and pregnancy, consulting with a plastic surgeon early on in the process can give them a better idea of what to expect long-term.

Considerations for Prophylactic Mastectomy and Pregnancy

If you are in the phase of life where you want to grow your family but are also at risk for breast cancer, there are some unique considerations that you will need to discuss with your healthcare providers before you make any treatment plans. 

Additional Considerations for Preventative Mastectomy and Pregnancy

Reasons for Preventative Mastectomy

Surgery Timing

  • Before pregnancy or additional pregnancies
  • After you have finished having children

Impact on Breastfeeding

  • Unable to breastfeed from breasts post-mastectomy
    • Consider formula or donor milk

Breast Reconstruction

  • Many breast reconstruction options are available
  • Provides aesthetic benefit 
  • Does not restore breastfeeding ability

Hormonal Effects

  • Pregnancy hormones might stimulate residual cancer cells to grow
  • No cause-and-effect relationship defined
  • Low risk of recurrence with monitoring.

Women navigating the complexities of preventative mastectomy and pregnancy must weigh their options diligently as they decide what is best for them and their families.

Preventative Mastectomy and Pregnancy or Breastfeeding

One of the primary considerations for women thinking about getting a prophylactic mastectomy is the surgery timeline relative to pregnancy and childbirth. Some women may choose to undergo the procedure before becoming pregnant to mitigate the risk of developing cancer as early as possible, while others prefer to delay the surgery until after having children.

Undergoing a prophylactic mastectomy usually involves the removal of all breast tissue, including all ducts and glands, which means a woman will no longer have the ability to breastfeed from the affected breasts. 

While there are more options now for feeding children than breast milk alone, women must consider the physical and psychological impacts of not being able to breastfeed future children compared to the risk of developing cancer in their children’s early years. If you plan to undergo a mastectomy before having children, you will need to consider alternative feeding options, like formula or donor milk.

For those who have always wanted to breastfeed their children, a delayed approach to surgery might be considered if your health allows. This way, you can postpone any mastectomy or reconstruction procedures until after your family is complete. 

After mastectomy, many women choose to undergo breast reconstruction. While this decision can influence the aesthetic and psychological outcomes of the surgery, it does not restore the ability to breastfeed.

Potential for Breast Cancer Recurrence After Pregnancy Hormones

Pregnancy induces significant hormonal changes in the body, including increased levels of estrogen and progesterone. In women who have had breast cancer, there is a concern that these hormonal fluctuations could potentially stimulate the growth of any remaining cancerous cells.

While the risk of breast cancer recurrence during or after pregnancy is relatively low, it is a consideration for women who have previously had breast cancer and undergone a mastectomy before pregnancy. Although there is no direct link from pregnancy to an increased risk of recurrence for women who have undergone breast cancer treatment and are in remission, close monitoring and collaboration with healthcare providers is important to make sure the cancer does not return.
