Breast cancer screening is a process in which various tests are conducted to detect breast cancer in its early stages when it is more treatable. This can include methods such as mammograms, clinical breast exams, and self-exams. Screening is important because early detection allows for more successful treatment outcomes and can potentially save lives. Researchers in this area focus on the development of new screening techniques, improving existing methods, and studying the effectiveness of screening programs in reducing breast cancer mortality rates. Additionally, research in this field also explores risk factors for breast cancer and the impact of early detection on patient outcomes.
