恶性黑色素瘤的发病率在世界各国呈上升趋势。其发病原因目前尚不清楚,但本病的发病与日光照射及地球大气层的环境保护有关。恶性黑色素瘤(MM)是原发皮肤瘤中恶性程度很高的一种肿瘤。在过去30年间,欧美各国的发病率明显升高。美国在1930年时,1500人中只有1人发病,到1980年在250人中就有1人发病,发病率升高6倍。本世纪末此病的发病率将会超过肺癌的发病率。在日本,1950年因恶性黑色素瘤死亡人数为29例,而1985年是297例,死亡人数增加10倍。这种急骤上升的发病率和死亡率,其原因至今虽不明确,但
The incidence of malignant melanoma is on the rise in all countries in the world. The cause of the disease is not yet known, but the onset of the disease is related to sunlight exposure and environmental protection in the Earth’s atmosphere. Malignant melanoma (MM) is a highly malignant tumor in primary skin tumors. In the past 30 years, the incidence of European and American countries has increased significantly. In the United States in 1930, only 1 out of 1500 people had an episode. By 1980, 1 out of 250 people had an episode. The incidence increased by 6 times. The incidence of this disease at the end of this century will exceed the incidence of lung cancer. In Japan, there were 29 cases of malignant melanoma deaths in 1950, compared with 297 cases in 1985, and the death toll increased by 10 times. The reason for this sudden increase in morbidity and mortality is not clear so far.
