Skin Cancer Risk and Vitamin D Levels

A new study reported online in the Archives of Dermatology concluded that as individual’s vitamin D level increases their risk for nonmelanoma skin cancer (NMSC) also seems to increase but factors such as untraviolet (UV) radiation exposure may complicate this relationship. The study was carried out among 3,223 white subjects in a health maintenance organization (HMO) with a high probability of developing NMSC, Between January 1997 and December 2001, subjects were assessed for levels of serum 25-hydroxyvitamin D (an indication of vitamin D levels), and parathyroid hormones, creatinine and calcium levels. Over 2/3 of the participants (n=2,257) seemed to have insufficient levels of vitamin D and the diagnoses of NMSC were made in 240 individuals including 49 with squamous cell carcinoma (SCC), 163 individuals with basal cell carcinoma (BCC) and 28 individuals with both (all forms of NMSC). Individuals who were not deficient in vitamin D seemed to have an increase risk of developing NMSC and although this relationship was positive it was not statistically significant for tumors developing on body parts routinely exposed to UV radiation suh as arms and legs. More research is needed in this area of study.

High Intake of Dietary Phosphate May Be Associated with Skin Cancer

Results of a study published in Cancer Prevention Research concluded that a high dietary intake of phosphate promotes tumor formation in an animal model of skin cancer.

Researchers applied a carcinogen found in cigarette smoke (dimethylbenzanthracene) to the skin of mice and then applied another chemical that stimulates cell growth. Mice were then fed a high phosphate diet (1.2% by weight) or a low phosphate diet
(0.2 percent). Those fed a high phosphate diet had 50 percent more skin papilla (initial stage of skin cancer development) compared to those on a low phosphate diet.

Although phosphate is a very important nutrient its intake has
increase dramatically over the past 30 years according public health researchers who say it has been added as an additive in processed foods such as meats, baked goods and soft drinks.

The researchers estimated a human dietary equivalent to the high phosphate diet of the mice would be 1,800 milligrams daily and that is a level many humans match or exceed. The human equivalent of a low phosphate diet would be 500 milligrams.

In 2006 the Department of Agriculture said the average phosphate intake of American male and females over two years of age was 1,334mg and the recommended daily allowance was 1,250 for pre-teens and teenagers and 700mg for adults.

The authors said that a low phosphate diet may help prevent cancer based upon these results obtained with a mouse model.

Melanoma-A Serious Skin Cancer

Wednesday, August 19th, 2009

picture-0611One of the guest interviewed this past week was a 33 year cancer survivor who had been given 3 months to live when diagnosed with melanoma. Melanoma is a serious form of skin cancer and usually can be avoided by reducing exposure to ultraviolet radiation from sunlight. When diagnosed in an early stage before metastasis it can often be successfully treated,

Traditionally surgery is used to remove cancerous tissue and in early stages may be all that is needed. Radiation and chemotherapy are not typically used except in advanced stages where there is metastasis.

There are some natural products that have shown promise when used for melanoma. Reducing sun exposure is crucial. A diet high in fruit and vegetables and whole grains is recommended. Studies have shown that vitamin D may suppress melanoma cell proliferation by up to 50% (good sources are dark green leafty vegetables and cold water fish) ; quercetin inhibits the invasiveness of melanoma cells in vivo; vitamin C and essential fatty acids inhibit the growth of melanoma cells in culture; mistletoe suppresses melanoma cell growth in vivo; genistein in soy products (legumes and soy beans) inhibits the growth of melanoma cells as effectively as chermotherapy drugs adriamycin and etoposide. The National Cancer Institute researchers also reported some success using a vaccine.

Research this month reported that starting to use of the tanning bed before age 30 increases the risk of melanoma by 75%. This same report stated that all types of ionizing radiation are carcinogens to humans and include: radon gas in homes cause lung cancer, plutonium and decaying products, radium and decaying products affecting the bones of medical patients, phosphorus 32 and its decaying products causing acute leukemia in medical patients, and radioiodines affecting the thyroids in children and adolescent survivors of nuclear reactor accidents.

New research is being reported daily so if you are in need of care for this type cancer ask you physician about the current natural products being used.
