The outcome of the lumpectomy depends on the type of lump found. If the lump is benign (whether it is needle aspirated or excised), no further treatment is required.
If the lump is malignant, the outcome depends on the degree to which the tumor has spread. Radiation therapy may be used in addition to surgery. In certain cases of malignant lumps, lumpectomy followed by radiation therapy is as effective as a radical mastectomy. Typically, lumpectomy does not require a breast replacement (prosthesis).
