Breast cancer is a cancer that develops from the breast tissue. Signs of breast cancer may include breast lumps, hard texture, poor mobility, change in breast shape, dimpled skin dimple sign, orange peel sign, bloody nipple discharge, and sunken or deviated nipples. Usually, the survival rate of breast cancer patients depends on the severity of the disease and their own physical condition, the more severe the disease, the lower the survival rate. Usually, according to the literature, the five-year survival rate for early stage breast cancer patients is over 98% and the 10-year survival rate is 90%. The survival rate is also increasing with the current medical technology and improved treatment methods. According to studies obtained from current medical technology: 1. The 5-year relative survival rate for patients with stage 0 or stage I breast cancer is close to 100%. 2. The 5-year relative survival rate for women with stage II breast cancer is about 93%. 3.Stage III breast cancer has a 5-year relative survival rate of about 72%. 4. Advanced breast cancer that has spread to other parts of the body is more difficult to treat and often has a worse outlook. The 5-year relative survival rate for metastatic or stage IV breast cancer is about 22%. Regardless of the stage of breast cancer, patients should not give up treatment and should maintain an optimistic attitude to face life and the disease.
