Breast cancer is the most common form of cancer affecting women; one in eight women will develop breast cancer throughout their lifetime. Breast cancer can sometimes also happen to someone pregnant. This rare form of breast cancer will not affect the pregnancy, but pregnant women must get treatment after birth to ensure cancer does not return.

After lung cancer, breast cancer is the second deadliest cancer that affects women. Treatment usually includes a mastectomy, which may be done while the woman is pregnant. 

Breast Cancer And Pregnancy

Breast cancer during pregnancy is relatively rare, accounting for only 1% of all breast cancer cases. The definitive cause is unknown, but it is believed to be a combination of hormonal and genetic factors.

The good news is that breast cancer during pregnancy can be treated successfully. The course of treatment depends on the stage of cancer and the health of the mother and baby. In most cases, a combination of surgery, radiation therapy, and chemotherapy will be recommended.

If you are pregnant and are diagnosed with breast cancer, it is necessary to seek treatment as soon as possible. With early diagnosis and treatment, the prognosis for both mother and baby is excellent.

What are the treatments for Breast Cancer?

There are a few different treatments for breast cancer, and the course of action will depend on the stage of cancer. If it is caught early, a lumpectomy (tumour removal) may be all that is needed. If it is more advanced, a mastectomy (removal of the breast) may be necessary. Chemotherapy and radiation are also common treatments for breast cancer.

Support sources for those going through treatment for breast cancer

Many support sources are available for those undergoing breast cancer treatment. Here are a few:

  • The National Cancer Institute offers resources and support for those affected by breast cancer, including information on treatment options and clinical trials.

  • The American Cancer Society also provides resources to help support breast cancer patients and their families, including information on treatment and coping with physical and emotional effects of cancer.

  • is a website that provides information on all aspects of breast cancer, from detection and diagnosis to treatment options and coping with the disease. The site also has an extensive forum where users can share their experiences and offer support to one another.

These are just a few support sources available to those affected by breast cancer. With so many options available, there is sure to be something that can help you or a loved one through this difficult time.


Although breast cancer is not common during pregnancy, it can happen. If you are pregnant and have any symptoms of breast cancer, be sure to see your doctor immediately. Many effective treatment options are available, so don't delay getting the care you need.
