Etiology

The number of new cells that appear in a healthy body is proportional to the number of dead cells, but under the influence of adverse factors, uncontrolled reproduction can begin: cells divide before reaching maturity, and as a result are unable to perform their initial functions. There are quite a lot of factors that can trigger the process of uncontrolled cell division, but the main factor for skin neoplasms is frequent skin injuries, ultraviolet radiation and chronic inflammatory processes, as a result of which cells have to regenerate quite actively, and as a result, control over division is lost.

Types of neoplasms

Benign neoplasms (atheroma, hemangioma, lymphangioma, lipoma, papilloma, birthmark, nevus, fibroma, neurofibroma, cylindroma) do not threaten human life, but if they are placed incorrectly or are large in size, they can cause malfunctions of other systems and/or organs.

Malignant neoplasms (basal cell carcinoma, melanoma, sarcoma, liposarcoma) grow quickly and aggressively, penetrating the surrounding tissues and organs, often with the formation of metastases.

Borderline or precancerous conditions of the skin (senile keratoma, pigmented xeroderma, cutaneous horn, Bowen's dermatosis) - formations, the tissues of which, under the influence of hereditary or current causes, have changed, gaining the potential to transform into malignant tumors
