A new study showed that a man exposed to sun are less likely to get prostate cancer than their less tanned one. However, there’s another problem and that’s skin cancer. The greater a person's lifetime sun exposure, the greater a person's risk of skin cancer.
The main arguments for this study are genes that let some people's bodies use vitamin D more efficiently. This means that vitamin D deficiency really does increase a man's risk of prostate cancer and mans sun exposure cuts this risk in half.
People living in the north and elderly people tend to get less time in the sun than young people living in southern climes. Unlike other vitamins, a person's main source of vitamin D isn't food; it's sunshine. The body makes its own vitamin D, but only when it's exposed to the sun.
Additional evidence of a vitamin D-prostate cancer link came from laboratory studies. Schwartz and colleagues found that prostate cancer cells are less likely to behave like cancer cells when exposed to vitamin D.
Some of researchers found a link of this first theory but the other not. John Brook’s researcher team decided not to take a one-time measure of vitamin D levels or to rely on people's estimates of sun exposure. They used a device to compare skin pigmentation on a person's exposed skin to pigmentation on that person's unexposed skin and then they calculated that person's sun exposure.
The researchers studied 450 non-Hispanic white Americans with prostate cancer and compared them with 455 similar men without prostate cancer.
The bottom line: Those with high sun exposure were 49 percent less likely to have prostate cancer.
The researchers also got blood samples from study participants. They looked for vitamin D receptor genes.
People who carried genes for particularly effective vitamin D receptors were 54 percent to 33 percent less likely to have prostate cancer, depending on the gene involved.
However, this current study does not prove vitamin D deficiency causes prostate cancer. It's too soon for people to start taking vitamin D in hopes of cutting their risk.
Anyway Vitamin D deficiency is today globally recognized for fighting against the importance, but now it seems that Vitamin D could be a good defending mechanism for other diseases.
