Skin cancer occurs when your skin cells start to grow abnormally. It often develops in areas exposed to ultraviolet rays from sunlight, tanning beds or carcinogens (cancer-causing chemicals). This damages the DNA in your skin cells which eventually causes the cells to become cancerous. As the cancer cells grow and multiply, they can spread to other parts of your body.
There are two main types of skin cancer:
This develops in the cells that give your skin its colour. Melanoma can develop anywhere on your skin, but often starts on the chest, back or legs as a new mole, or you may notice changes in an existing mole. While melanoma is a less common type of skin cancer, it’s more serious as it can quickly spread to other parts of your body if it isn’t caught early and treated.
Non-melanoma skin cancer
Non-melanoma skin cancer refers to any cancer that occurs in your skin and is not melanoma. Several types of skin cancer fall within this category. The most common types are:
The following factors may increase your risk of developing melanoma:
You should protect your skin from the sun whenever you are outside, especially during the summer, as most melanomas are associated with exposure to the sun’s ultraviolet rays. Use a high-factor sunscreen, ideally SPF (sun protection factor) 30 or higher.
Sunscreen can protect you against two types of UV rays — ultraviolet A and ultraviolet B rays. Be sure to apply a thick coat of sunscreen 30 minutes before you go outdoors to allow the cream to sink into your skin. Reapply after every two hours as sunscreen often breaks down with sun exposure or after sweating and swimming. Don’t forget to apply the sunscreen on your legs, tops of your feet, ears, face, scalp and neck. You can use a spray sunscreen for hard-to-reach areas such as your back or ask someone to help.
Stay in the shade during midday hours
The sun's ultraviolet rays can reach you even on hazy and cloudy days, as they reflect off surfaces such as snow, sand, cement and water.
Avoid direct sunlight between 10am and 3pm when the sun’s ultraviolet rays are at their strongest. Shelter under a tree, umbrella or any other type of shade.
As ultraviolet rays can reach your skin even when you are in the shade, you should still apply sunscreen.
Avoid directly exposing your skin
Clothing provides a barrier against the sun's rays. The more skin you cover, the better. Dark-coloured clothes that are tightly woven provide more protection from ultraviolet rays than light-coloured, loosely woven clothing.
However, keep in mind that the SPF of a T-shirt is less than 15, so you shouldn't rely on clothing alone — still use sunscreen. You can also invest in clothing specifically designed to protect you from the sun's ultraviolet rays — clothing will be rated according to its UPF (ultraviolet protection factor), with a higher UPF providing more protection.
Wear a hat
Hats with broad brims will shade your neck, face, ears and eyes. The hat should cover your whole head. For the best protection, make sure your hat is made from a fine, tightly woven, dark fabric. Some hats also offer additional protection as they are made from fabrics with a high UPF.
Avoid straw hats as they have holes that allow the sun's ultraviolet rays to reach your skin. Baseball hats provide limited protection, as they do not cover your ears. If you go outside wearing a baseball hat, apply sunscreen with an SPF of 30 or more to the back of your neck and ears.
Protect your eyes and the sensitive skin around your eyes by wearing sunglasses on bright days all year round. Look for sunglasses that block 100% of UVA and UVB rays — this will reduce your risk of developing cataracts earlier in life. Wraparound sunglasses are ideal since they also block the sun's rays coming from the sides.
Avoid tanning beds
There is no safe tanning bed, sun lamp or tanning booth. Just one tanning session increases your chances of getting skin cancer. Exposure to the ultraviolet radiation emitted by tanning beds can also increase your risk of eye cancer and cataracts.
There is a range of treatment options for skin cancer, including:
You should see your doctor if you notice any symptoms of skin cancer, such as new moles or changes in existing moles, or the appearance of a lump or discoloured patch of skin. Early detection will mean you receive treatment before the cancer spreads to other parts of your body.
