Skin cancer damages the skin through the uncontrolled growth of malignant cells. The so-called melanoma (black skin cancer) often develops from unusual or changing moles.

In Germany, approximately 14,000 people are diagnosed with melanoma each year. A major risk factor is excessive exposure to ultraviolet (UV) radiation, such as from sunbathing or tanning beds, as well as repeated sunburns.

People with fair skin types, red hair, or a family history of skin cancer are particularly at risk.

In advanced cases, the disease may present as moles that ooze, bleed, or itch. However, warning signs can also include asymmetrical shape, irregular borders, large size, or changes in color. These changes should be monitored carefully.

Examination using dermatoscopy (reflected-light microscopy) allows detailed assessment of moles across the entire body. In addition, digital mole mapping and analysis can be used to monitor suspicious lesions over time and help avoid unnecessary surgical procedures.
