Unconventional methods of cancer treatment make claims that can not be scientifically substantiated. They commonly claim to be effective against cancers that are considered incurable, and tout treatments with relatively few, if any, side effects.
The use of these unconventional methods may result in the loss of valuable time and the opportunity to receive potentially effective therapy. It is always important to remain in the care of a qualified physician who uses accepted methods of treatment or who is participating in scientifically designed investigational therapies.

Alternative medicine
Complementary and alternative medicine covers a wide range of healing philosophies that conventional medicine does not commonly accept or make available to its patients. Some of these practices include the use of acupuncture, herbs, homeopathy, therapeutic massage, and Far Eastern medicine to treat health conditions.
These therapies may be used alone as an alternative to conventional medicine, or in addition to conventional medicine, in which case they are referred to as complementary. Many are considered holistic, meaning their focus is to treat the whole patient - physically, mentally, emotionally, and spiritually. These treatments are not widely taught as a part of the medical curriculum, are not generally used in hospitals, and, for the most part, are not covered under insurance policies.
Many cancer patients try various complementary and/or alternative medicine techniques during the course of their treatment, and although they may not work for everyone, some patients benefit by managing their symptoms or side effects. One important caveat, is to discuss any complementary or alternative treatments you may be considering with your doctor to be sure nothing interferes with your conventional care. For instance, dietary supplements such as herbs or vitamins may be "natural", but not necessarily "safe". They may lessen the effectiveness of certain anticancer drugs, or when taken with other drugs or in large doses, may actually cause harm. Since supplements of this nature are not governed by the FDA (Food and Drug Administration), and a prescription is not necessary to purchase, it is up to the consumer to make informed and conscientious decisions regarding their use.

Gene therapy
Gene therapy is an approach to treating potentially fatal or disabling diseases by modifying the expression of an individual's genes toward a therapeutic goal. The premise of gene therapy is based on correcting disease at the DNA level and compensating for the abnormal genes.
Replacement gene therapy replaces a mutated or missing gene, most often a tumor suppressor gene, with a normal copy of that gene which serves to keep cell growth and division under control. The p53 gene, the most common gene mutated in cancer has become a prime target for gene replacement, and has met with some success in inhibiting cell growth, inhibiting angiogenesis (the development of a tumor's blood supply), and inducing apoptosis (cell death).
Knockout gene therapy targets the products of oncogenes (a gene that can induce tumor formation) in an effort to render them inactive and reduce cell growth.
