If the information sounds unbelievable, it probably is. Some Web sites tout miracle cures for cancer and other diseases and ailments prematurely or without valid or adequate evidence. Be on guard for over-sensationalized reporting of medical information. Check with other sources to substantiate questionable medical claims. Check for links.
Reputable sites are more likely to link to others with similar information.
The more links the better. Beware of sites that link only to a search engine. Take a breather. Be wary of any site that urges you to take immediate action. No matter how good a plan or remedy might seem, check the information against other sources or consult a health care professional before acting on it.
