Where Can I Find Trustworthy Info on Alternative Medicine?
It can sometimes be hard to believe that alternative treatments we might hear about from family and friends have not been shown to work. There may be convincing stories of a person who was told they had cancer, then, after using this treatment, was cured and healthy again.
It's certainly understandable to want to believe these hopeful stories. But stories about amazing cures cannot be thought of as evidence that a treatment works. Most of the time, there’s no way to be sure the stories are true.
Why is it hard to find trustworthy information about alternative medicine?
Testing may not be required by law
Treatments that do not make claims to treat specific diseases or side effects may not have to go through scientific studies to show they are safe and effective. This is true for many dietary supplements. There are requirements about how dietary supplements must be made and labeled, but not requirements that they be tested to find out whether they actually help, or whether they are safe to use.
Some providers of alternative methods are careful to not make public claims about their effectiveness and safety. This allows them to avoid the testing that standard methods need to go through.
Some treatments are assumed to be safe
Some people choose alternative therapies because they think these treatments don't have harmful side effects. This is often not true. Some alternative therapies have been found to cause serious or even life-threatening side effects. Others have simply not been tested in rigorous clinical trials. But since most of these problems are not reported to the US Food and Drug Administration (FDA), they are not studied.
Some treatments are assumed to be effective
There are those who think that treatments derived from folk remedies that have been used for thousands of years must be safe and work. However, just because a treatment method has been used a long time does not mean that it is safe and effective.
Many traditional therapies have not been studied thoroughly, as this type of research wasn't often done in the distant past. When scientific studies are not done, it can be hard to tell when an illness is truly helped by a treatment. Alternative treatments that are given for illnesses that go away on their own may be given credit for curing the person. Or the treatment might make the person feel better for a short time but have no lasting effect.
Finally, keep in mind that many of the methods that were used in the distant past were simply the best option available at the time, because more effective treatments had not yet been developed.
The placebo effect
It’s quite common for people to feel better after almost any kind of treatment that they expect to help them. This is called the placebo effect. The placebo effect means that if the person expects the treatment to help, they may feel better after getting it – even if the treatment does nothing for the underlying problem. This effect usually lasts only a short time, and seems to have something to do with the body’s own ability to relieve pain or certain other symptoms for up to a few hours.
The placebo effect may explain one of the reasons that some people keep using certain types of alternative treatments that don’t help the underlying disease. If they feel better for a few hours, it may be worth it to them. But the treatment may not have the same effect on everyone who tries it.
Finding reliable studies can be a challenge
Controlled human studies (clinical trials) are the best way to find out if a treatment works. Clinical trials to show that a treatment works must include large groups of people, compare new treatments to those known to work, control who gets which treatment, and carefully measure the benefits and harms of each treatment. This can take a good bit of time and money. But clinical trials are vital to show that a treatment is safe and effective.
When looking for studies, it is important to know whether a source can be trusted. It is best to look for studies published in reliable, mainstream medical journals. Be careful with articles shared through social media, as they often contain misleading or even harmful information. For more information about sources of treatment information, see Evaluating New Cancer Treatments.
If it’s hard to find information from a reliable source about a cancer treatment method, it might mean that the method has not yet been studied enough to show whether it is safe and works in people.
Some websites or journals might be set up just to promote certain types of treatment. They may offer pseudo-science – statements that look and sound scientific, but aren’t. This can make it harder to learn about these treatments, since the information put out by these types of sources can make it sound like they work and have few or no side effects. And companies that offer products for sale may have “research” on their website that sounds good but was never reviewed by experts in the field. So, the results may not be trustworthy.
The bottom line is that if you can’t find reliable information from researchers who don’t have a stake in the product, it’s very likely that the research proving that it works in humans has not been done. That means there’s no proof that the method works in people.
