It turns out to be true. To answer this question we will quote from Dr Paul Banwell - founder and former Head of Melanoma and Skin Cancer at East Grinstead.
He notes that the term non-melanoma cancer describes a group of cancers that develop in the upper layers of the skin. And it explains how staying in the sun leads to skin cancer and especially warns about the appearance of spots and also the mistakes we should not make in winter.
When the temperature drops to zero degrees and the sun hides, you might think you don't need sunscreen. Dr Banwell points out that very few people use sunscreen in the winter. However, this is a mistake, as the winter sun can also lead to skin cancer. Regardless of whether you see the sun, because this is the so-called solar constant.
“Everybody equates UV damage with just the sun coming up and shining, but you also get the sun's constant, which is UV radiation, which is UVA and UVB rays. We know that visible light and infrared light also damage the skin.
All these processes, mostly related to free radicals, cause skin damage and therefore potential skin cancer, explains the specialist. The good news is that sunscreens are able to block these components of the sun's constant and minimize the risk of this cancer. Wear sunscreen all year round, I recommend it to all my patients.”
Symptoms of skin cancer differ depending on whether it is non-melanoma or melanoma. Signs of non-melanoma skin cancer include red spots on the skin that may bleed, crust over, and ulcerate, so they won't heal. While melanoma is characterized by changes in moles. This type of cancer can be life-threatening as it spreads to other parts of the body.
