Cancer therapy spans the disciplines of surgery, radiation therapy, chemotherapy, and immunotherapy. To these tumor-specific therapies may be added the general modalities of support therapy, including rehabilitation, and psychological therapy, and the multiplicity of non-specific therapies, such as pain management and transfusion. In more general terms, cancer therapy may be subdivided into two broad categories: curative therapy and palliative therapy. The former therapy usually consists of surgically excising the malignant lesion with the expectation of achieving cure. Radiotherapy has become recognized as another curative measure, particularly in treating Hodgkin’s disease and carcinoma of the cervix. Chemotherapy may have a role in curative therapy but is more properly applied in adjuvant therapy in connection with either radiation or surgery.
