One of the most recognized symptom of breast cancer is a lump or mass in the breast tissue, which can be detected by getting a mammogram at a health facility or conducting a self-examination at home. Mammograms are X-rays of the #breast that can detect tumors at a very early stage, before they would be felt or noticed otherwise. During a mammogram, your breasts are compressed between two firm surfaces to spread out the breast tissue. Then an X-ray captures black-and-white images of your breasts that are displayed on a computer screen and examined by a doctor who looks for signs of cancer. Women at average risk are recommended to have a mammogram every year starting at age 45. Starting at age 54, women are recommended to have a screening mammogram every 2 years as long as they remain healthy.
