Alternative medicine refers to unproven or disproven methods used instead of standard medical treatments to prevent, diagnose, or treat cancer. They have either not been thoroughly tested in clinical trials, or they have been tested and found not to work against cancer. Some examples of alternative methods include special diets, certain supplements and herbs, high doses of vitamins, homeopathy, laetrile, and Rife machines. Many alternative medicine providers suggest a combination of these types of treatments.
Standard treatments are based on research studies that show that the treatment is safe and effective against one or more types of cancer. There are also standard treatments to help with many of the side effects of cancer and cancer treatment. Examples of standard treatments include surgery, radiation therapy, chemotherapy, immunotherapy, targeted therapy, hormonal therapy, and supportive medicines to help with pain, nausea, or other problems.
Alternative medicine is different from complementary therapies. Complementary methods are used along with and support standard treatments. Alternative methods are used instead of standard treatments.
Treatments that are not used in mainstream medicine may be described as unconventional, non-conventional, and non-traditional by mainstream medical doctors. These terms may be used to describe any complementary or alternative therapy. Some treatments, such as traditional Chinese medicine or Native American healing, are also used in complementary or alternative therapies. Of course, to the person who is part of the culture practicing these treatments, their native methods are usually called traditional, while Western medicine is the non-traditional way.
People with cancer might think about using alternative methods for a number of reasons:
Some alternative methods may be appealing because they use your own body and mind, or things found in nature. Some even promise wellness using methods that sound simple, natural, and without side effects, which is rarely true of standard cancer treatments.
While some alternative methods rarely cause harm, others can have dangerous or even life-threatening side effects. Even when there are few harms with a particular alternative treatment, research has shown that people who use alternative methods instead of conventional cancer treatment for the most common curable cancers have a greater risk of dying from their cancer.
By definition, alternative methods have not been studied enough to show that they are effective in treating cancer, or they have been studied and shown to not be effective. Methods that are proven by research to effectively fight cancer tend to be used in standard medicine fairly quickly.
The decision to use alternative methods is an important one, and it’s yours to make. We have put together some suggestions to help you think through the issues and make the most informed and safest decision possible.
There tends to be much less high-quality, objective information about alternative methods than about mainstream treatments. This is one of the reasons that it is sometimes impossible to say much about whether an alternative method is likely to help you, or even how safe it might be. This is why you should try to learn as much as you can about each treatment before you use it. Even if some information isn’t available, the limits of what is known can help you make your decision.
The choice to use alternative methods is yours. You can use them more safely if you:
