Mammography is a specialized medical imaging technique used to examine breast tissue. It involves taking X-ray images of the breasts to detect early signs of breast cancer and other abnormalities. The procedure is typically performed in a dedicated facility by a trained radiologic technologist, and it usually takes about 15 to 30 minutes. During a mammogram, the breast is placed between two plates that compress it to obtain clear images. Women are generally advised to start regular mammography screenings at age 40, or earlier if they have a family history of breast cancer. Early detection through mammography can significantly improve treatment outcomes.
