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 affect the function of the organ, sometimes no treatment is needed.
Sometimes benign tumors may be removed for cosmetic reasons, however. Benign tumors of the brain may be removed because of their location or harmful effect on the surrounding normal brain tissue.
If a tumor is malignant, treatments include:
A combination of these methods
If the cancer is in one location, the goal of treatment is usually to remove the tumor with surgery. 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.
However, lymphoma is rarely treated with surgery. Chemotherapy and radiation therapy are most often used for treating lymphoma.
