The Women’s Breast Screening Project is organized to standardize the breast cancer screening work so that the benefits of screening can be fully reflected, regardless of the selection of screening tools, training of professionals, and technical standards of the operation process are strictly stipulated to ensure the quality of the screening work, as long as women who participate in this screening can be exempted from the threat of breast cancer with an interval of one and a half years of examination and prevented from the disease before it happens. 1. The cure rate can be significantly increased, as the cure rate of stage 1 cancer detected by screening is over 90%. 2. Breast-conserving surgery can be performed for early stage breast cancer, which can not only be cured, but also have a high quality of life. 3.Since the treatment is simple, the economic burden of expensive chemotherapy drugs can be avoided.
