Skin Cancer

There are two main types of skin cancer; malignant melanoma (cancer in moles), and the non-melanoma group (basal cell and squamous cell carcinoma).

Each year approximately 1 in every 10,000 people in the UK will develop a new case of malignant melanoma. It accounts for about 1500 deaths annually in the UK. Sun radiation is a contributing factor in 90 per cent of all cases of skin cancer. Skin cancer is caused by exposure to sunlight, particularly the ultraviolet (UV) rays.

The risk of developing skin cancer is increased following episodes of sunburn, but there may be a delay of many years before the cancer appears. A small number of cases are caused by hereditary conditions, but they are also triggered by exposure to sun rays. Sun beds can also cause skin cancer.

The warning signs of the disease are changes in existing moles such as in colour or shape and size. Also bleeding or sores that heals slowly on the mole itself. If a new mole appears and seems uneven or it has ragged edges. Any unusual sore, lump or blemish lasting more than a few weeks or if areas of skin become scaly, itchy, tender or red, as well as areas that ooze, bleed or become crusty.

To prevent skin cancer it is important to void excessive exposure to the sun, especially the midday sun (from 11am to 2pm).

It is important that the cancer be detected as early as possible. The patient's chances of being cured largely depend on how early the treatment is started. If the disease is not treated, it will cause death.
