Skin Cancer, Vitamin D3 and Sunlight

Can Vitamin D3 supplementation Reduce Your Risks of Skin Cancer?

Full Disclosure: I am a 58 year old cancer survivor who worshiped the sun in my youth. I burned frequently. Some of those sunburns where severe. I was diagnosed with a blood cancer called multiple myeloma in 1995. Studies confirm an inverse relationship with serum vitamin D3 and multiple myeloma. I had a bone marrow transplant in ’95 increasing my risk of skin cancer further.

Skin Cancer Mind MapI mention this only to go on record that this blog post is not about getting people to get less sun exposure. Some people will sit in the sun regardless. This blog post is designed to raise the possibility that supplementing with vitamin D3 may be an inexpensive way to reduce the risks of both Non-Melanoma Skin cancer (BCC and SCC) as well as Melanoma Skin Cancer.

As you can see from the illustration of skin cancer to the left, we are talking about a complicated, sometimes aggressive, sometimes not aggressive, cancer. There are a host of evidence-based, non-toxic therapies that can reduce the risk of both non-melanoma and melanoma skin cancers.

The studies linked and excerpted below state that humans are healthier with vitamin D3 in their blood. Further, while a little bit of U.V. light is okay, too much U.V. predisposes you to skin cancers. I see the solution as being Vitamin D3 supplementation. I take 1000 mg x 3 daily with food.

I am both a long-term cancer survivor and cancer coach. Have you been diagnosed with either basal cell or squamous cell carcinoma? Or melanoma? Scroll down the page and let me know.

Thank you,

Ultraviolet radiation.

“The International Agency for Research on Cancer has noted that there is sufficient evidence from studies in animals and in man to establish ultraviolet radiation as a human carcinogen. Skin cancer has been the most commonly studied cancer site with respect to UV radiation. The nature and timing of sun exposure appear to be important determinants of both the degree of risk and the type of skin cancer

It has been estimated that solar ultraviolet radiation accounts for approximately 93 percent of skin cancers and about half of lip cancers…

Several recent studies suggest a possible inverse relationship between ultraviolet radiation exposure and risk of non-Hodgkin lymphoma, colon, breast and prostate cancer, and investigators have speculated that this might be due to the higher serum levels of vitamin D stimulated by high lifetime sun exposure.

Further, studies conducted within cohorts using stored pre-diagnostic serum suggest that those with high levels of vitamin D have lower incidence rates of a number of malignancies, particularly colon cancer. However, since serum vitamin D levels can be raised through the use of supplements without increasing risk for skin lip and other known UV-related cancers, changes to health policy with regard to exposure are not merited at this point.”

Cutaneous vitamin D synthesis versus skin cancer development

“Clinicians including dermatologists have to recognize the convincing evidence that the protective effect of less intense solar radiation outweighs its mutagenic effect. In agreement with this assumption, it was concluded that many lives could be prolonged through careful exposure to sunlight or more safely, vitamin D-supplementation, especially in non-summer months…”
