Treatment of breast cancer depends on the type of cancer, location and size of the tumour, and how much is it has spread. Treatment typically involves partial or complete surgical removal of breast tissue, chemotherapy, radiation, and hormone replacement therapy. The type of surgery recommended by the doctor will depend on the stage and growth of the cancer. While lumpectomy involves a partial removal of breast tissue along with the lump, a mastectomy involves a complete removal of the breast. In rare cases, this could also involve the removal of lymph nodes under the arms. Breast cancer surgery is by far the most effective treatment recommended by most doctors. Radiation therapy for 5-8 weeks is usually recommended after surgery to ensure removal of residual cancer cells in the breast. Chemotherapy at a breast cancer treatment hospital in India will ensure that the cancer does not recur and will deal with any metastasis.
