Skin cancer and the power of the sun: The ozone hole is getting bigger and the danger of harmful effects on humans is getting worse. As part of this, over the past few years the media has repeatedly reported alarming growth rates in the case of cancer skin cancer. But there are different forms of skin cancer - where sun and sun rays as causes are very clear.
Skin cancer: forms and types
By far the best known is probably the black skin cancer, the malignant melanoma. But the term skin cancer is a collective name for other malignant diseases of the skin.
The forms of skin cancer have in part different triggers, differ in frequency, course and prognosis and are treated with different therapy. So there is the so-called white skin cancer, which is also referred to as bright skin cancer in addition to the black skin cancer.
Skin cancer: forms such as melanoma, basalioma, spinalioma
More common than malignant melanoma are basal cell carcinoma (basal cell carcinoma) and squamous cell carcinoma (spinalioma, spindle cell carcinoma). These two forms of skin cancer are also summarized under the term white or pale skin cancer.
In all forms of skin cancer the incidence has increased in the past. According to the World Health Organization (WHO), white kidney cancer is estimated at around two to three million per year, and black skin cancer (malignant melanoma) from 130, 000 new cases worldwide.
Frequency of skin cancer
According to the Robert Koch Institute, malignant melanoma does not account for 4% of all malignant tumors in Germany - around 16, 000 people suffer from black skin cancer every year, women more often than men.
The incidence rates in light skin cancer are not recorded nationwide, but are higher - estimated at least one in every 1, 000 people annually.
Basal cell carcinoma (basal cell carcinoma) occurs about five times more frequently than squamous cell carcinoma (spinalioma). However, mortality from black skin cancer is much higher.
Rare forms of skin cancer
In addition, there are rarer forms of skin cancer, which can develop from various structures of the skin. These include, for example, malignant tumors of connective tissue (fibrosarcomas), sweat or sebaceous glands, vascular cells (angiosarcomas), muscles (myosarcomas), tactile cells (Merkel cell carcinomas) and Kaposi's sarcoma, which is common in AIDS. According to many experts, skin cancer does not include cutaneous lymphoma - tumors that have typical skin changes but originate from the cells of the blood and bone marrow.
