(Best Syndication News) - The US recommended daily allowance (RDA) of vitamin C should be increased to 200 milligrams per day for adults, scientists from the Linus Pauling Institute at Oregon State University suggests. The current RDA for vitamin C for women is 75 milligrams and 90 milligrams for men. The scientists from the institute put forward that an increase in the RDA could reduce heart disease, stroke, and cancer. The call for the higher intake of vitamin C was published in Critical Reviews in Food Science and Nutrition.

Balz Frei, a professor and director of the Linus Pauling Institute at Oregon State University, said that some clinical trials were essentially imperfect. Of course, the Linus Pauling Institute has long been recommending vitamin C for improving health.

(Best Syndication News) - The US Centers for Disease Control and Prevention (CDC) reported a dramatic increase in people calling the quit helplines and visiting a federal government website to help them stop smoking. The CDC attributes the increase to the recent public service announcements featuring people with serious health conditions caused by smoking.

There were almost 200,000 more phone calls made to 1-800-QUIT-NOW, which helps connect people to state quitlines. There were also over 400,000 more unique visitors to www.smokefree.gov, which is a federal website that offers a step-by-step guide on how to quit smoking.

Cancer Treatment Uses Body’s Immune System

(Best Syndication News) Patients with several types of cancers could benefit from new treatments that are now ready for wide-spread testing. The therapy, which boosts the immune system, provided promising early results in patients with advanced non-small cell lung cancer, melanoma, and kidney cancer.

"Based on the positive response rates to these drugs and longevity of many of these responses, we believe that new clinical trials should move forward," says Suzanne Topalian, M.D., professor of surgery and oncology at Johns Hopkins.

Aspirin and other NSAID Pain Relievers might reduce Skin Cancer

(Best Syndication News) - A study from Denmark found that squamous cell carcinoma, and malignant melanoma might be reduced when a person takes aspirin, ibuprofen, or naproxen on a regular basis. The reduction was seen when patients filled at least two prescriptions for nonsteroidal anti-inflammatory drugs (NSAIDs). They had a 15 percent decreased risk for developing squamous cell carcinoma and a 13 percent decreased risk for developing malignant melanoma. The study results were published online in CANCER, which is a journal of the American Cancer Society.

Sigrún Alba Jóhannesdóttir, BSc, of Aarhus University Hospital in Denmark along with colleagues investigated medical records from northern Denmark from 1991 through 2009. They found 1,974 diagnoses of squamous cell carcinoma, 13,316 diagnoses of basal cell carcinoma, and 3,242 diagnoses of malignant melanoma. They also compared information from 178,655 individuals that did not have skin cancer and compared this against their prescriptions. They were looking for prescription of two or more refills of an NSAID.

(Best Syndication News) - The tumor growth rate of certain cancers could be increased with low oxygen levels, according to recent study from researchers at the University of Georgia. The study was published in the early online edition of the Journal of Molecular Cell Biology.

The current consensus of most researchers is that genetic mutation is the main cause of cancer growth. This study suggests another cause: low oxygen levels (hypoxia) in cells. Oxygen may play a role in unruly tumor growth in certain types of cancer. Prior research showed that low oxygen levels were a contributing factor to cause cancer to advance, however, they did not point to it as the main cause.
