About Skin Cancer

What is skin cancer?

Skin cancer is the uncontrolled growth of abnormal cells in the skin. It occurs when DNA damage is caused to skin cells (most often by ultraviolet radiation from sunshine or tanning beds), that trigger mutations, or genetic defects, that lead the skin cells to multiply rapidly and form malignant tumours.

Skin cancers can grow slowly and it can take some years before a cancer is noticed. But sometimes a skin cancer can grow very quickly, within a few months.

Skin cancer is the most common form of cancer in Northern Ireland, accounting for over 30% of all cancers here.

Some NI skin cancer facts:

  • About 3,780 people in Northern Ireland develop skin cancer each year
  • Of these around 330 are malignant melanomas, the most serious type of skin cancer
  • Each year skin cancers kill around 50 people in Northern Ireland
  • Melanoma shows higher rates for females, with one fifth more appearing in the female population
  • Rates of melanoma increase with age, although a significant number of cases still occur in people under 35
