Ultraviolet (UV) radiation is a form of energy that the sun produces. You can’t see UV radiation because its wavelengths are shorter than visible light.

Ultraviolet (UV) radiation is necessary because it provides vitamin D to help you survive, but it’s also harmful with overexposure. You can take care of your skin and prevent skin cancer from ultraviolet radiation by wearing sunscreen outdoors and staying out of the sun when it’s at its brightest in the middle of the day. Nearly 80% of a person’s lifetime sun exposure occurs before age 18. You can become a good role model and foster skin cancer prevention habits for your family by taking preventive measures when you go outside.

The UV energy that the sun produces reaches the Earth and provides vitamin D for your body to help you survive. You can also find UV radiation in human-made sources like tanning beds. Exposure to too much ultraviolet radiation greatly increases your risk of developing skin cancer.

Over time, the sun’s ultraviolet light damages the fibers in your skin called elastin. When these fibers break down, your skin begins to sag, stretch and lose its ability to go back into place after stretching. Your skin also bruises and tears more easily, in addition to taking longer to heal. So, while sun damage to your skin may not be apparent when you’re young, it’ll show later in life.

Cumulative sun exposure causes basal cell and squamous cell skin cancer, while episodes of severe blistering sunburns, usually before age 18, can cause melanoma later in life.

You might see ratings from the UV index on weather reports. The numbers represent the risk of unprotected sun exposure to the average person. You may think that the lower index numbers mean you don’t have to take action, but the risk of sun exposure to unprotected skin always exists.

Skin cancer is the uncontrolled growth of skin cells. While healthy cells grow and divide in an orderly way, cancer cells grow and divide in a rapid, haphazard manner. This abnormal growth causes tumors that are either benign (noncancerous) or malignant (cancerous). There are three main types of skin cancer:

Long-term effects of ultraviolet radiation exposure or overexposure to the sun can lead to premature aging and skin cancer. The sun’s UV rays reach the DNA within the cells in your skin and cause them to malfunction. You can reduce your risk of skin cancer by wearing protective clothing when you go outdoors and reapplying sunscreen throughout the day. You can also wear protective accessories like sunglasses to shade your skin and eyes from ultraviolet radiation. Treatment is available for all types of skin cancer, but your outlook is best when you receive an early diagnosis and treatment.

The stratum corneum exists in the outermost layer of your skin (epidermis) and is your body’s natural barrier to protect you from cancer-causing ultraviolet radiation. Too much sun exposure can break down your body’s natural defense, which can lead to skin cancer. Even though you have this barrier, you still need to take steps to protect your skin from UV radiation.

The cure for most skin cancers is early detection and treatment to remove cancer from your body. An early diagnosis, especially for melanoma, targets cancer before it spreads to other parts of your body. Nearly 90% of people diagnosed with basal cell carcinoma make a full recovery after treatment to remove cancer.

Too much ultraviolet radiation causes skin cancer. Your body needs some UV light for vitamin D, which is a vitamin you need to survive. When your skin has too much exposure to UV radiation, it damages your cells. Within your cells, you have DNA. DNA tells your cells how to form and function within your body. Too much UV radiation targets the DNA in your cells, which causes them to misunderstand their function. As a result, your cells divide and replicate too frequently. Your cells then clump together to form tumors, which can be cancerous.

Ultraviolet radiation from the sun is the primary cause of skin cancer, but UV light from tanning beds is just as harmful. Exposure to sunlight during the winter months puts you at the same risk of exposure during the summertime.

The sun releases ultraviolet (UV) radiation, which provides vitamin D to your body. But too much sun exposure can cause wrinkles and skin cancer. You can protect your skin from too much UV exposure by wearing sunscreen when you go outside. Skin cancer from UV radiation is treatable and leads to a good prognosis if detected early.

The most common warning sign of skin cancer is a change on your skin. Changes are typically a new mole, a new skin lesion or sore, or a change to an existing mole.
