In a recent study concerning turmeric and skin cancer, as well as a few other plants in the ginger family, researchers determined that the plant extracts act by inhibiting oxidative stress and improving antioxidant defenses, which "might" be why the extracts protect against UVA associated melanoma. Other studies have shown that there is a protective effect, but the mechanism of action is, as yet, unclear.
When experts are investigating the benefits of drugs and natural compounds, they usually try to explain "how" it works. Although in the case of many drugs on the market, including popular antidepressants, researchers were never able to explain how the drugs worked
experts indicate that the placebo effect is increasing. Interestingly, a sugar pill works 30-40% of the time. In some cases, it works even more often. As long as the volunteers are unable to determine (either by taste or appearance) whether or not they are getting the "active" compound, the placebo works just as well in 30-40% of all cases.
Studies concerning turmeric and skin cancer have yet to reach the stage where volunteers are recruited. But the placebo effect cannot have any impact on a disease like that. It isn't just about how the patients feel. It's about whether or not the disease is progressing or not ,
they can access the effect that a compound is having on the cells and tumors. If the tumors are shrinking, then the compound is working.
So far, all of the studies concerning turmeric and skin cancer have been conducted using animals. Volunteers have been recruited for studies concerning other types of cancer, as well as for liver disorders, Alzheimer's and arthritis
Some plants in the same family have different medicinal activities, including ginger. The active compounds in ginger are referred to as gingerol. It works well for dizziness, nausea, motion sickness, tinnitus and Meniere's disease among other health problems.
Any plant that has antioxidant activity has the potential to be useful for treating or preventing cancers of all kinds. Those that have natural anti-inflammatory activity have a higher potential to be effective. That's why animal studies concerning turmeric and skin cancer have been conducted. In the test tube, curcumin has been shown to have both antioxidant and anti-inflammatory activity.
There are other plants that have both antioxidant and anti-inflammatory activity. Alternative practitioners have developed something of a nutritional cocktail for the treatment of inoperable cancers and for those patients that prefer not to undergo surgery or chemotherapy.
Some of the better supplement manufacturers provide curcumin and other ingredients that are believed to be beneficial in preventing a number of age related diseases. Like the studies concerning turmeric and skin cancer, preliminary studies concerning the anti-aging effect of neutraceuticals have been positive.

major chemicals that courses skin cancer :cigrate and alcohol
cigarettes is one the chemicals that caused cancer i believe we all know. For years, cancer experts have been advising the public to quit the habit and decrease their cancer risk. The connection between alcohol and cancer, however, is not as well known. Skin cancer is only one of the many cancers that can be caused from smoking and alcohol use.
Actinic cheilitis is a condition that affects the lips. Affected lips become puffy, dry, cracked, or ulcerated and change color, often to bright red or white. It is considered to be a pre-cancerous condition. In five to ten percent of cases, it develops into squamous cell carcinoma. The condition can affect people of all ages, regardless of sex, but typically strikes men over fifty. Risk increases with age. Actinic cheilitis is caused by a lifetime accumulation of UV damage. Smoking, alcohol, and poor oral hygiene are also believed to increase the risk of this condition.
Research has shown that cigarette smokes contains as much as five thousand chemicals. Of those, over seventy are carcinogens. Every cigarette smoked exposes the skin and other organs in the body to numerous toxic substances that increase the risk of developing cancer.
According to Dr. Jan Nico Bouwes Bavinck, one of the leading researchers in a study on smoking and skin cancer at Leiden University Medical Center in the Netherlands, exces smoking triples the risk of developing squamous cell carcinoma. The study's data indicated that smoking may inhibit immune system function, leaving skin vulnerable to the cancer causing chemicals found in cigarette smoke.Even that is why ministry of health warned that smokers are liable to die young
Smoking reduces available oxygen to the skin. Statistics say that oxygen supply to skin is decreased for close to an hour after smoking for just ten minutes. Skin cells are damaged by the deprivation. Nicotine's effect of narrowing blood vessels and reducing circulation also damages skin cells. Smoking also thins the skin and interferes with healing.
Experts say that alcohol is the second largest risk factor for oral cancer. While exactly how alcohol functions is unexplained, there are theories. It is believed that the liver damage brought on by alcohol causes cellular changes. These cellular changes may lead to modifications in the tissues of the mouth and throat.
A second theory is that alcohol increases hormone levels. There have been a large number of studies showing the link between increased levels of certain hormones and the incidence of cancer. According to statistics by the American Cancer Society, drinkers are six times more likely to be diagnosed with oral cancers than those who abstain from alcohol use.
When alcohol is combined with smoking, the incidence of cancer is even higher. Cells dehydrated by alcohol are more vulnerable to cigarette's cancer causing chemicals. According to experts, you can lower your risk of cancers by giving up cigarettes and reducing or abstain from alcohol. It takes more than ten years for your risk level to return to that of a nonsmoker and nondrinker.
If you think you are safe because you only drink or smoke socially, think again. As few as two drinks a day for men and one drink a day for women is enough to increase your risk. With so many cancer causing chemicals in cigarettes, a single smoke can do damage to the skin and increase your risk of skin cancer.ABSTAIN IS THE BEST
