Breast Cancer and Pregnancy

Breast cancer is the most common cancer in pregnant women and tends to affect women in their mid-30s. About one in every 1,000 pregnant women get breast cancer, the disease can be devastating to both the mother and her child -- so it is essential that pregnant women and their doctors continue to do routine breast exams and thoroughly investigate any suspicious lumps and symptoms.

A major problem is that a lot of changes take place in a woman's breasts during pregnancy. This makes it harder to identify small lumps. Lumps can also be mistaken for a normal change in pregnancy. In addition, breast cancer tumors in pregnant women are often larger and more advanced by the time they are detected than lumps in women of the same age who are not pregnant. Although pregnancy doesn't cause breast cancer, the hormonal changes in the body can accelerate its growth.

How Is Breast Cancer Diagnosed In Pregnant Women?

The best thing you can do while pregnant is to see your obstetrician regularly. These doctor visits, called prenatal (or "before birth") visits, are very important in keeping both you and your baby in the best possible health. During these visits, your obstetrician will perform a breast exam to check for suspicious breast changes.

It is also important to regularly perform breast exams on yourself. Your doctor or nurse can teach you how to do this properly.

If a suspicious lump is found, your doctor will likely do a biopsy. A mammogram may not be as helpful because of the increased density of the breasts due to pregnancy. An ultrasound might be done as well.

During the biopsy, a small sample of the suspicious tissue will be removed with a needle or by making a small cut. This sample is then thoroughly examined using a microscope and other methods to detect any cancer cells.

What Happens to my Baby if I Have Breast Cancer?

First of all, abortion of the baby does not improve the mother's chances of surviving breast cancer.

Second, there is no evidence that breast cancer can harm the baby. What can harm the baby are some of the treatments for breast cancer -- and these depend on how advanced the cancer may be. This is another reason why it is so important to detect these and other cancers early.

If the cancer is still in the early stages (Stage I or II), the doctor will most likely recommend that you have surgery to remove either the suspicious lump (lumpectomy) or the affected breast (mastectomy). Mastectomy is the preferred surgery in the first and second trimester as there is a concern regarding a prolonged delay in giving radiation treatment. Lumpectomy is usually reserved for the third trimester. Surgery, in general, is safe during any trimester of pregnancy .

October is National Breast Cancer Awareness Month, and a new study reveals why a high number of women with the disease still prefer to have the entire breast surgically removed instead of just the tumor. It's not always because doctors recommend it.
