CANCER PREVENTION IN PRIMARY-CARE - MELANOMA - PREVENTION AND EARLY DIAGNOSIS .5.

Over the past two decades there has been a rapid rise in the numbers of people developing and dying from malignant melanoma. Sunlight is the main aetiological factor linked with melanoma. Exposure to the sun is a risk factor that can be modified provided that people are aware of the dangers. Health promotion campaigns can play a part in producing such change. General practitioners and practice nurses have an important part to play in providing those most at risk with information and advice about sensible sun exposure and sun protection measures. Campaigns to reduce delay in diagnosis by a combination of professional and public education have been reported from several centres around the world. The effects of these campaigns in reducing the depth distribution of cutaneous malignant melanoma have sometimes been encouraging, but in other instances have shown little effect. Until there is clear evidence that early detection reduces mortality from melanoma, the opportunistic promotion of early detection may not be cost effective and will fail to reach all sections of the community at risk. At the present time, therefore, the emphasis should be on the primary prevention of skin cancer.
