What is Skin Cancer?
Skin cancer is a form of cancer that affects the cells in the skin. It is commonly caused by prolonged exposure to ultraviolet (UV) radiation from the sun, tanning beds, and effects of ageing.
There are 2 types skin cancer
Non-Melanoma Skin Cancer
Basal cell carcinoma is the most common type of skin cancer and usually appears as a small, red bump or nodule on areas of the body that have been exposed to UV radiation over time.
Squamous cell carcinoma may look like scaly patches or bumps, they may be irregular in shape or ulcerate, and may appear anywhere on the body that are usually exposed to sunlight.
Melanoma Skin Cancer
Melanomas are considered more dangerous than other forms of skin cancer because they can spread quickly (metastasis).
Melanomas can occur anywhere on the body, not only in areas that get a lot of sun. The first sign of a melanoma is usually an unusual looking freckle or mole, that may also itch or bleed.
Sun damage is the cause of most skin cancers. Too much exposure to the sun’s UV radiation damages your cells. The DNA within those cells can be targeted, causing irregularities in their replication patterns, and ultimately interrupting normal cell function. This can lead to abnormal cellular division that clumps together forming tumors, that may have cancerous properties.
Protecting Yourself from UV Radiation
To stay as safe as possible in the sun it is essential that you take steps towards preventing such dangers from occurring by protecting yourselves from overexposure.
- Apply sunscreen with an SPF of 30 or greater 30 minutes before going out in the sun and every few hours after. Remember to reapply sooner if you get wet or sweat significantly.
- Wear sunglasses with total UV protection.
- Choose cosmetic products and moisturisers that offer UV protection.
- Limit your direct sun exposure during the hours of 10 am and 4 pm, when UV radiation is at its peak.
- Check your skin regularly. Be mindful of existing skin growths and check for any changes or new growths, contact a medical professional as soon as you notice any abnormal skin changes – such as new moles, changes to existing moles or skin lesions and sores.
