Advice from the Cleveland Clinic:

Younger women generally do not consider themselves to be at risk for breast cancer. Only 5 percent of all breast-cancer cases occur in women under 40 years old. However, breast cancer can strike at any age, and all women should be aware of their personal risk factors for breast cancer.

There are several factors that put a woman at high risk for developing breast cancer, including:

• A personal history of breast cancer or high-risk lesion found by biopsy.

• A family history of breast cancer, particularly in a mother, daughter or sister.

• History of radiation therapy.

• Evidence of a specific genetic chance (BRCA1/BRCA2 mutation). Women who carry defects on either of these genes are at greater risk for developing breast cancer.

Should women under age 40 get mammograms?

In general, regular mammograms are not recommended for women under 40 , in part, because breast tissue tends to be more dense in young women, making mammograms less effective as a screening tool. In addition, most experts believe the low risk of developing breast cancer at a young age does not justify the low-level radiation exposure or the cost of mammography. However, screening mammograms may be recommended for younger women with a family history of breast cancer and other risk factors.
