A majority of nonmelanoma skin cancers NMSC and a large percentage of melanomas are associated with exposure to UV radiation from the sun.
UV exposure is a powerful attack on the skin, creating damage that can range from premature wrinkles to dangerous skin cancer. Damage from UV exposure is cumulative and increases your skin cancer risk over time. The unrepaired damage builds up over time and triggers mutations that cause skin cells to multiply rapidly. That can lead to malignant tumors. The degree of damage depends on the intensity of UV rays and the length of time your skin has been exposed without protection.
Location is also a factor. If you live where the sun is strong year-round, your exposure level and risk increases. You can easily reduce your likelihood of developing skin cancer by taking care to protect yourself against UV radiation. UVB facts and risks. UVB penetrates and damages the outermost layers of your skin. Overexposure causes suntan, sunburn and, in severe cases, blistering. UVB intensity fluctuates. UVB rays can be filtered and do not penetrate glass. Your skin remembers and records all the UV exposure over the years which contributes to your long-term risk of skin cancer.
Even low UV levels can be harmful when exposed for long periods. Too much UV radiation can cause skin and eye damage, sunburn, tanning and skin cancer. Sunburn is a UV radiation burn to the skin.
In Victoria's summer months, skin can burn in as little as 11 minutes and can take days or weeks to heal. Find out more about sunburn treatment at Better Health Channel. Sunburn prevention is best. Always check the sun protection times on the free SunSmart app and use a combination of sun protection measures when required.
UV also causes skin sagging, blotchiness and roughness. Photosensitivity is extreme sensitivity of the skin or eyes to UV radiation. This means the skin can burn more easily, increasing your risk of skin cancer. Some medications can also make you more sensitive to UV radiation, making you more likely to get sunburned. And certain medical conditions can be made worse by UV radiation.
Your skin makes vitamin D naturally when it is exposed to UV rays from the sun. How much vitamin D you make depends on many things, including how old you are, how dark your skin is, and how strong the sunlight is where you live. Vitamin D has many health benefits.
It might even help lower the risk of some cancers. Dietary sources and vitamin supplements do not increase skin cancer risk, and are typically more reliable ways to get the amount you need.
The US Centers for Disease Control and Prevention CDC has also recommended ways for communities to help prevent skin cancer by reducing sun exposure, including educational interventions in schools and providing shade at schools, recreational sites, and work sites.
Many people believe the UV rays of tanning beds are harmless. This is not true.
