<unk>  is a type of cancer of the<unk> . Treatment usually involves a lumpectomy or mastectomy to surgically remove the tumour. Chemotherapy and/or radiotherapy may be necessary, but the specific treatment often depends on the characteristics of the underlying<unk>  cancer. Invasive cancer or extensive ductal carcinoma in situ is primarily treated with modified radical mastectomies. The procedure consists in the removal of the<unk> , the lining over the chest muscles and a part of the lymph nodes from under the arm. In cases of noninvasive cancers, simple mastectomies are performed in which only the<unk>  with the lining over the chest muscles is removed. Patients suffering from cancer that has not spread beyond the nipple and the surrounding area are often treated with<unk> -conserving surgery or lumpectomy. They usually undergo radiation therapy after the actual procedure to prevent recurrence. A<unk> -conserving surgery consists in the removal of the nipple, areola and the part of the<unk>  that is affected by cancer. In most cases, adjuvant treatment is part of the treatment schema. This type of treatment is normally given to patients with cancer to prevent a potential recurrence of the<unk> . Whether adjuvant therapy is needed depends upon the type of cancer and whether the cancer cells have spread to the lymph nodes. In<unk> 's<unk> , the most common type of adjuvant therapy is radiation following<unk> -conservative surgery. Adjuvant therapy may also consist of anticancer drugs or hormone therapies. Hormonal therapy reduces the production of hormones within the body, or prevents the hormones from stimulating the cancer cells to grow, and it is commonly used in cases of invasive cancer by means of drugs such as tamoxifen and anastrozole.
