皮肤癌的发生与许多因素有关,如长期日光暴晒,尤其是夏天在太阳底下暴露时间很长却不进行任何防晒措施,及经常接触石油、沥青、砷、焦油等化学物质,或者溃疡长期不愈等。而一般中老年人是皮肤癌的好发人群并且发病率较高,男性发病多于女性。 The occurrence of skin cancer is related to many factors such as long-term sunlight exposure, especially exposure to the sun for a long time in the summer without any sun protection measures, frequent exposure to chemicals such as petroleum, asphalt, arsenic, tar, or long-term ulcer Wait. In general, the middle-aged and elderly people are a good-risk skin cancer and have a higher incidence of disease in men than in women.
