Breast cancer surgery is a critical treatment option for breast cancer, involving procedures such as lumpectomy, mastectomy, and sentinel lymph node biopsy. A lumpectomy, also known as breast-conserving surgery, removes the cancerous tumor and a small margin of surrounding tissue, while a mastectomy involves removing the entire breast to eliminate the cancer. Sentinel lymph node biopsy involves removing the first few lymph nodes to which cancer cells are likely to spread, helping to assess whether the cancer has spread beyond the breast. Symptoms leading to surgery may include a breast lump, skin changes, or nipple discharge. The choice of surgery depends on factors like the size and stage of the tumor, patient preference, and overall health. These surgeries can often be performed on an outpatient basis, allowing patients to return home the same day and recover in a comfortable environment.
