Treatment also varies based on the type of tumor, whether it is benign or malignant, and its location. If the tumor is benign (meaning it has no potential to spread) and is located in a "safe" area where it will not cause symptoms or disturb the proper functioning of the organ, sometimes no treatment is needed. Sometimes benign tumors may be removed for cosmetic reasons, however. If a tumor is malignant, treatments include surgery, radiation, chemotherapy, or a combination of these methods. If the cancer is confined to one location, the goal of treatment is usually surgical removal of the tumor and cure. If the tumor has spread to local lymph nodes only, sometimes these can also be removed. If all of the cancer cannot be removed with surgery, the options for treatment include radiation and chemotherapy, or both. Some patients require a combination of surgery, radiation and chemotherapy. In contrast, lymphoma is usually not treated with surgery and chemotherapy; radiation therapy may be the treatment of choice.
