How common is breast cancer during pregnancy?

Breast cancer is the most common cancer in pregnant women. It tends to affect women in their mid-thirties. Only about 1 in every 1,000 pregnant women is diagnosed with breast cancer. However, the disease can be devastating to both the mother and her child. Therefore, it is essential that pregnant women and their doctors continue to do routine breast exams and thoroughly investigate any suspicious lumps.

A major problem is that a lot of changes take place in a woman's breasts during pregnancy. This makes it harder to identify suspicious lumps. 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.
