It can be difficult sometimes to conduct evidence-based medicine clinical trials on these methods of treatment because there may not be clear-cut measurements that can tell us how effective they are in an isolated manner. For example, someone may be doing some form of complementary medicine while also getting other standard treatment. How do you determine which did what? More and more scientifically based research is being done now and some therapies have been proven to be beneficial for cancer patients.
There are lots of websites that claim something works. They may be self reporting by a company and not credible conducted studies that are evidence-based and conducted in the rigid manner in which clinical trials are to be carried out. These claims sound wonderful and even imply that it's a "cure for cancer" where there may be nothing that scientifically supports those claims. Be cautious of advertisements that claim that for a fee they will mail you the cure for your cancer.
If what they were selling really was a cure then an NCI-designated cancer center would be offering it and telling you about it. The U.S. government founded the National Center for Complementary and Alternative Medicine as part of the National Institutes of Health with the intended goal of providing information about what is safe and effective regarding these types of therapies. Ask your doctors or SmartBridge Health for input regarding information you have read about or heard so you can weed out accurate information from claims that may not be correct. There are some types of therapies that would interfere with the treatments your doctor has given you. For example, certain vitamins in high doses may impair the effect of some chemotherapy drugs. There are other types of therapies that your doctor may encourage you to do, such as acupuncture or yoga.
