According to the American Cancer Society, breast cancer is the second most common cancer for women in the U.S.

Know what to look for

Regular breast self-exams, along with knowing the early warning signs of breast cancer, are key for early detection. If breast cancer is found early, when it’s small and hasn’t spread, there’s a better chance that treatment will be successful, the American Cancer Society explains. Five symptoms to look out for include:

1

A new lump in the breast or underarm.

2

Any changes in breast shape or size, such as swelling in any part of the breast, or swollen lymph nodes in the underarms or near the collarbones.

3

Changes in breast skin or nipple area, like thickening or swelling.

4

Pain in the breast.

5

Changes to the nipples: if the skin is red or flaky; if they pull inward; or if there’s discharge other than breast milk, such as blood.

Although it’s less common, men can get breast cancer too. A lump in the breast is the most common sign for men, but they can also have the same symptoms as women.

If you or a loved one notice any of these changes, it is important to schedule an appointment with your primary care physician (PCP) or OB-GYN as soon as possible. Your doctor will order appropriate testing.

What is a breast cancer screening?

This screening checks the breasts for cancer in women with an average risk of breast cancer. High-risk women (such as those with a close family history of breast cancer or women with specific genes) may need other testing. Breast cancer screenings can’t prevent cancer, but they can help find it early, when it is easier to treat. Without symptoms, your doctor will recommend the best time and frequency to start regular breast screenings.

When to be screened for breast cancer

The U.S. Preventive Services Task Force recommends that all women be screened for breast cancer every other year, beginning at age 40 and continuing through age 74.
