Malignant melanoma is the sixth most common of all tumours. Melanoma is caused by harmful ultraviolet radiation. Increased travel (beach holidays) and tanning bed use has caused an increase in the disease. In 2010, there were 2,817 invasive melanomas diagnosed in Sweden. Age-adjusted incidence was 31.9/100,000 among men and 2.6/100,000 among women. The total incidence increase was 4.4 percent.
In 2010, 470 people died due to melanoma, of which half were over age 75.
Early diagnosis with a high proportion of thin melanomas provides a relative five-year survival rate of 93 percent for women and 86 percent for men. Informing the population about melanoma facilitates early diagnosis and improved sun and tanning bed habits should be able to halt the increase rate for the disease.
Purpose and objectives:
All persons diagnosed with invasive melanoma are registered via the INCA portal. For research purposes, in situ melanoma is also registered within Region Västra Götaland and Region Stockholm-Gotland. In other regions, data on in situ melanoma is retrieved via the Swedish Cancer Registry.
The inclusion rate is above 95 percent most years. At present, there are about 50,000 cases preliminarily registered from 1990 (or the year the specific registry began) onward.
The coverage rate is the number of cases of melanoma in the registry/number of cases in the quality registry. In 2011, the coverage rate was estimated at 95 percent.
Validation is only done in conjunction with registration.
Note: Variable lists are updated on a regular basis and should therefore be seen as preliminary. For the latest version, please contact the registry.
