The relationship between vitamin D, skin cancer and use of sunscreen is complex and is often misunderstood.

While it is true that vitamin D deficiency has been linked to an increase in cancer rate, including skin cancer, the role of sunscreen remains important in protecting from harmful ultraviolet (UV) radiation.

According to research, experimental studies suggest that vitamin D metabolites can help deal with skin cancer by triggering apoptosis (natural cell death) in malignant cells, angiogenesis (blood vessel formation) and spread (rapid growth) Stop, and promote discrimination (normal cell growth (general cell development).). These effects can potentially reduce the risk of skin cancer and improve pregnancy by slowing down the growth of tumors and making treatment more effective.

According to the National Library of Medicine, “In experimental studies, vitamin D metabolite increases the apoptosis of malignant cells, prevent angiogenesis and proliferation and increase discrimination, potentially reduce skin cancer growth and after diagnosis Diagnosis of the disease. “

It also states that some assistant is human data. We review the links between sun risk, vitamin D and skin cancer.

Vitamin D and Cancer

Vitamin D is synthesized in the skin through exposure to sunlight, especially UVB rays. Research indicates that vitamin D may have protective effects against some cancer due to its role in regulating cell growth and discrimination at sufficient levels.

A study showed that people with vitamin D deficiency had a greater phenomenon of various cancer, including colorectal and breast cancer.

In addition, vitamin D supplementation is associated with low mortality for advanced cancer. However, the relationship between vitamin D levels and skin cancer is particularly fine.

While some studies suggest that high vitamin D levels may be correlated with increased incidence of skin cancer such as melanoma, this is not the reason.

Instead, it throws light on the need for contact with a balanced sun – it is sufficient to maintain healthy vitamin D levels without increasing skin damage and later cancer growth.

Role of sunscreen

Studies show that the body produces 1,25 (OH) D to help maintain calcium levels. In recent years, low vitamin D has been linked to many diseases. In particular, the skin can fully produce vitamin D, which can be associated with skin cancer.

It also states that the enzyme 25-hydroxylus is not always active, but is triggered by vitamin D3 and UV-B light.

It allows active vitamin D (1,25 (OH) 2D) to be made within and use within the cell. Vitamin D. receptor (VDR) is found in both melanocytes and keratinocytes.

Which means that the enzyme 25-hydroxylus, which helps in vitamin D processing, is not always active, but becomes active by vitamin D3 and UV-B rays.

Sunscreen plays an important role in protecting the skin from UV radiation, which is a well -established risk factor for skin cancer.

Regular use of broad spectrum sunscreen can significantly reduce the risk of melanoma and non-melonoma skin cancer growth by blocking or absorbing harmful rays.

The American Academy of Dermatology recommends using a sunscreen with at least SPF 30, applied generously and re -applies every two hours outside.

While sunscreen can prevent vitamin D synthesis due to its protective barrier, it does not completely eliminate it.

Many people can still produce adequate vitamin D if they apply sunscreen properly in contact with contingent sun during daily activities without significant risk.

In addition, dietary sources of vitamin D – such as fatty fish, stronghold foods, and complement – can help maintain sufficient levels only without relying on the contact of the sun.

While vitamin D deficiency is associated with an increase in cancer mortality, the use of sunscreen is necessary to prevent skin cancer.

It is important in finding a balance: Protecting the skin from harmful UV radiation and receiving sufficient sun risks for vitamin D synthesis.

Individuals should consider both sun safety practices and dietary sources or supplements to ensure optimal health results.

Said that it is also important to note that there was no evidence in the recent meta-analysis from the National Library of Medicine that vitamin D deficiency increases the risk of melanoma. However, it suggests that low vitamin D levels may be associated with thick tumors in diagnosis and a worse disease can be diagnosed.
