Breast cancer is one of the most common cancers in women.
Women more than 20 years of age should know the signs of breast cancer and the best ways to find it early. Begin by standing in front of a mirror. Look at your breasts with your hands above your head, with your arms down at your side and your chest muscles flexed. Look for any changes in the skin or size of your breasts. Next, feel each breast while standing in the shower.
