What is skin cancer?
What is skin cancer ? The term “skin cancer” encompasses various cancerous diseases of the skin, which occur in various forms of appearance. The so-called black skin cancer ( malignant melanoma) and light skin cancer are distinguished. The latter include basal cell carcinoma and squamous cell carcinoma . In addition, there are a few other very rare forms of skin cancer (angiosarcoma, dermatofibrosarcoma protuberans, malignant fibrous histiocytoma, liposarcoma, carotid sarcoma, etc.).
Definition and frequency of skin cancer
The incidence of skin cancer has been rising steadily for several decades. According to estimates by the World Health Organization (WHO), every year two to three million new cases of bright skin cancer and more than 250,000 new cases of malignant melanoma occur every year.
Malignant melanoma accounts for 4% of all malignant neoplasms and is responsible for about 1% of all cases of cancer. The cases of bright skin cancer are not covered extensively in Germany. However, some cancer registries suggest that there are about 300 new cases of white skin cancer per 100,000 inhabitants each year. As a result, up to 170,000 people in Germany suffer from invasive forms of bright skin cancer each year. Approximately 80% of this is attributable to basal cell carcinoma , which is the most common malignant tumor in humans and about 20% to squamous cell carcinoma .
If skin cancer is detected at an early stage, there are very high healing chances for all species.
