We know you can spot a counterfeit handbag from a mile away -- but are you savvy enough to sort out the myths that surround breast and ovarian cancer? Deborah Lindner, MD, OB/GYN with the Women's Group of Northwestern and women’s health expert is here to help:

Myth: Young women cannot have breast cancer.

Fact: While breast cancer is rare in young women, five percent of all breast cancers diagnosed each year in the U.S. occur in women under 40. Additionally, breast cancer in young women is generally more aggressive and results in lower survival rates.

Myth: Men cannot have breast cancer.

Fact: Although breast cancer is more common in women, it is a disease that men can develop as well. More women develop breast cancer because their breast cells are constantly exposed to the growth-promoting effects of the female hormones estrogen and progesterone.

Myth: The time to really start paying attention to my breast health is around age 40 when I start having mammograms.

Fact: Women should conduct breast self-exams every month starting at age 20. The breast self-exam is the first line of detection for breast cancer and it is important to become familiar with your breasts at an early age so you can notice any changes in the breast tissue. The best time for a woman to perform a breast self-exam is at the end of her period, when her breasts are least tender. If a woman no longer has a period, she should do it at the same time each month.
