This article can be found at Quackwatch.com. It is important to me to get out information on what constitutes as alternative medicine and why it can be fraudulent. Consumers need to be aware. You will inevitably come across those that promote cures for cancer and other ailments.

In the article Steven Barrett, MD classifies Alternative medicine in three different ways:

1. Genuine -- these alternatives have met science based criteria for safety and effectiveness
2. Experimental -- these alternatives are unproven but have a plausible rationale and are undergoing responsible investigation.
3. Questionable -- these alternatives are groundless and lack a scientifically plausible rationale.

Another way Dr. Barrett describes the different alternatives methods are:

1. Those that work
2. Those that don't work
3. Those we are not sure about

Most of the alternatives fall into the --Those we are not sure about category.

Don Herbert, also known as television's science teacher Mr.Wizard, died at his home Tuesday of bone cancer. He was 89.

Mr. Wizard's target audience was kids (baby boomers: you may already know this) and his lessons taught youngsters to use the thinking skills of scientists through workshop experiments using simple household items. His 1950s series Watch Mr. Wizard was so good it won a Peabody Award in 1954, and Herbert was one of David Letterman' first guests when the show Late Night With David Letterman debuted in 1982. Herbert's show made it to Nickelodeon too and ran from 1983 to 1991. Reruns were shown until 2000. Nickelodeon's Mr. Wizard episodes are available here.

A native of Waconia, Minnesota, Herbert graduated from LaCrosse State Teachers College in 1940; served as a U.S. Army Air Corps pilot during World War II; and worked as an actor, model, and radio writer before reaching fame on Mr. Wizard in Chicago -- and then New York -- on NBC.

He is survived by six children and stepchildren and by his second wife, Norma.

Scientists have determined that mouth cancer develops in two different ways which dictates the seriousness of the disease. This finding, revealed on Tuesday, could lead to better prevention and treatment. In laboratory experiments with healthy, early, and advanced cancer cells, researchers were able to pinpoint differences in the cells that determined the aggressiveness of the cancer. They found faults in the p53 gene, which stops damaged cells from dividing, and in the p16 gene, which helps regulate and prevent cancer from developing. Both changes are linked to more aggressive tumors. This is first-time evidence that some mouth cancer tumors are more aggressive than others and are unfortunately linked to poor patient survival.

Oral cancer typically stems from pre-cancerous lesions, changes, or patches in the mouth -- all of which are early signs of cancer. Recognizing which pre-cancerous changes are more likely to develop into aggressive tumors would allow doctors an insight that could help them prescribe the best treatment.

Smoking, use of chewing tobacco, and heavy alcohol consumption are the leading causes of mouth cancer. And smoking and drinking are a very dangerous combination. Like lung cancer, mouth cancer usually develops in people age 50 or older.
