There's both laser therapy & surgery. Although chemotherapy is often used to shrink the cancer first then they use one of the above to finish it off, so to speak.

What is Insulin Potentiation Therapy (IPT)? Insulin Potentiation Therapy is a protocol for administering traditional chemotherapeutic drugs using Insulin to transport the chemotherapeutic drugs across the cell membrane into the cancer cells. A much lower dose of the highly toxic drugs is required, because IPT treatment targets only the cancer cells, sparing the good cells. The cancer cells get the chemotherapeutic drugs, not the normal cells. Therefore, the patient does notsuffer the severe side effects so common with conventional chemotherapy – no hair loss, vomiting, or fevers. The quality of life remains high during treatment. What cancers respond to IPT? IPT treatment has been reported to work well for many different types of cancers. There are also reports of IPT bringing responses and remissions to patients with some very difficult cancers, even cancers in late stages. Of course, each patient is evaluated anew, depending upon the type of cancer, the virulence of the individual cancer cells, and the stage of development of the cancer when the patient first comes for treatment. Over time, regular chemotherapy dosages may so compromise the patient's blood counts, immune system, and organ function as to preclude further treatment or even cause organ damage resulting in the patient's death. IPT eliminates the "lesser of two evils" decision all cancer patients face when diagnosed. Patients fare well as they experience a gentle and effective answer to cancer. It does appear that the percentages for remission and survival are at least as good as with conventional chemotherapy, and probably much better. IPT has been used successfully in foreign countries for over 70 years. It has only recently been used in the USA, and there are many happy patients who now support this modified form of chemotherapy. They do say that IPT is not only more effective than conventional chemotherapy, but also that it is certainly more comfortable than the suffering they experienced with regular chemotherapy Cancer cells are voracious in fighting for the life-sustaining glucose found in the blood stream. With 16 times the number of insulin and insulin-like receptors of a healthy cell, cancer cells steal any and all essential nutrients from the blood stream before the good cells can get any. This is why, in advanced stages of cancer, the tumor continues to grow while the patient becomes emaciated and simply wastes away. Added to this, because of the cancer cell’s amazing internal protection against toxins, standard administered chemotherapy must be in large enough quantities to force its penetration into the cancer cells. This results in the indiscriminate penetration and killing of healthy cells as well, frequently leaving the patient with fever, nausea, vomiting, hair loss, and a substantially diminished quality of life.

There are many different types of therapies available besides Chemotherapy, however they depend on the type of cancer you have. No one therapy is good for all cancers. Do your own research and confer with your doctors. Choose the best therapy that is proven for your type of cancer. Do not be afraid of Chemo if it has a high success rate for your diagnosis. There are many new and wonderful drugs to treat the side effects of chemo and make it much more tolerable than it was several years ago.
