Breast cancer screening is a process used to detect breast cancer in its early stages, often before symptoms appear. The most common screening method is a mammogram, which is an X-ray of the breast. Women are generally advised to start regular screenings at age 40, but those with a family history of breast cancer may need to begin earlier. In addition to mammograms, other screening methods include clinical breast exams performed by healthcare professionals and breast self-exams that individuals can do at home. Early detection through screening can lead to more effective treatment options and better outcomes for those diagnosed with breast cancer.
