Signs and Symptoms of Breast Cancer
Breast cancer symptoms vary widely — from lumps to swelling to skin changes — and many breast cancers have no obvious symptoms at all.
In some cases, a lump may be too small for you to feel or to cause any unusual changes you can notice on your own. Often, an abnormal area turns up on a screening mammogram (X-ray of the breast), which leads to further testing.
In other cases, however, the first sign of breast cancer is a new lump or mass in the breast that you or your doctor can feel. A lump that is painless, hard, and has uneven edges is more likely to be cancer. But sometimes cancers can be tender, soft, and rounded.
It's important to have anything unusual checked by your doctor.
According to the American Cancer Society, any of the following unusual changes in the breast can be a symptom of breast cancer:
swelling of all or part of the breast
skin irritation or dimpling
nipple pain or the nipple turning inward
redness, scaliness, or thickening of the nipple or breast skin
a nipple discharge other than breast milk
a lump in the underarm area
These changes also can be signs of less serious conditions that are not cancerous, such as an infection or a cyst. Again, it’s important to get any breast changes checked out promptly by a doctor.
It’s smart to perform a monthly breast self-exam so you are familiar with your breasts and have a better chance of noticing any changes. And you should visit your doctor if you experience breast changes.
If you're over 40 or at a high risk of breast cancer, you should also have an annual mammogram and physical exam by a doctor. The earlier breast cancer is found and diagnosed, the better your chances of successful treatment.
