can skin cancer protect you from Alzheimer's?

There is little reason to rejoice, if you have skin cancer. However, a study performed at Albert Einstein College of Medicine in New York did find that study participants who had been diagnosed with non-melanoma skin cancer were 80 percent less likely to develop Alzheimer’s disease.

The 1,102 participants in the study were 70 years old or older and were followed for an average of 3.7 years. They were checked annually for symptoms of Alzheimer’s disease and skin cancer.

At the start of the study, 109 of the people had been diagnosed with either basal cell or squamous cell skin cancer in their past medical history. None of the participants had signs of dementia.

During the study period, 32 additional people developed non-melanoma skin cancer and 126 people were diagnosed with some form of dementia. Only two of those who had non-melanoma skin cancer developed Alzheimer’s disease.

It is unclear what the link is between non-melanoma skin cancer and Alzheimer’s disease. There seems to be a number of possible factors that could explain the study results.

Study author Dr. Richard Lipton, a professor at Albert Einstein College of Medicine told Science daily that "One possible explanation could be physical activity."

Lipton went on to say, "Physical activity is known to protect against dementia, and outdoor activity could increase exposure to UV radiation, which increases the risk of skin cancer."

Another possibility is increased vitamin D exposure from being outside since studies have shown vitamin D could offer some protection against Alzheimer’s.

Lipton told Huffingtonpost, "Biologically, the most interesting idea has to do with cell division."

He explained that in Alzheimer’s disease, brain cells die and are not replaced. In cancers, the opposite is true. Cancer cells replicate nonstop. Perhaps the process of excessive cell division in these certain types of skin cancers, is protecting the brain from Alzheimer’s disease.
