Skin Cancer: Understanding Risks, Signs, and Prevention

Skin cancer and the power of the sun: Not only given the ozone hole, sunbathing increases the risk of harmful effects for humans. As a result, the media has repeatedly reported frightening growth rates of skin cancer in recent years. But there are different forms of skin cancer – in which the sun and sun rays are apparent as causes.

Skin cancer: forms and types such as melanoma, basalioma, spinalioma

The term skin cancer is a collective term for other malignant diseases of the skin. The forms of skin cancer sometimes have different triggers, differ in frequency, course and prognosis and are treated with different therapies.

In all forms of skin cancer, the incidence has increased in recent times. According to the World Health Organization (WHO), there are around two to three million new cases of white skin cancer and 130,000 new cases of black skin cancer (malignant melanoma) worldwide.

 

incidence of skin cancer

In Germany, malignant melanoma accounts for not quite 4 per cent of all malignant tumours – statistically speaking, every 50th person suffers from melanoma, women more often than men.

The incidence of non-melanoma skin cancer is not recorded nationwide but is higher – an estimated 213,000 people per year.

Basal cell carcinoma (basalioma) occurs around five times more frequently than squamous cell carcinoma (spinalioma). However, the mortality rate for black skin cancer is much higher.

Rare forms of skin cancer

There are also rarer forms of skin cancer that can develop from different structures in the skin. These include, for example, malignant tumours

  • of the connective tissue (fibrosarcoma),
  • the sweat or sebaceous glands,
  • the vascular cells (angiosarcoma),
  • of the muscles (myosarcoma),
  • the touch cells (Merkel cell carcinomas), as well as
  • Kaposi’s sarcoma, which often occurs with AIDS.

According to many experts, skin cancer does not include cutaneous lymphomas – tumours that show typical skin changes but originate in blood and bone marrow cells.
