Skin cancer is a group designation of several types of tumors originating from various parts of the epidermis. Basaloma is often observed on the face in old age. There is a solid colored pearl knot or group of small nodules, which form a small hardly towering plaque. Subsequently, these bundles dissolve and formed telephium with a smooth bright red bottom and a thick edge. Around this new lesions are dense bundles. On the surface basalioma can point pigmented inclusions (pigment variety) or its surface has a yellowish-white color. In scraping of the erosion surface or ulceration there are revealed atypical cells.

Treatment: electro coagulation, electro scission within healthy tissue, ointments under the control of cytology, there may be short-distance roentgen therapy, cry destruction, surgical excision. Prognosis is good, because rodent cancer develops very slowly, does not metastasis and well cured. Employability is usually kept.

Flat surface of basal-cell carcinoma is usually localized on the trunk. There are plaques of different sizes with pink, covered with thin scales atrophic center and overlooking sparkling narrow trim of small dense pinkish-red or whitish-yellow, inclined to the growth of nodules on the edge. Progression of the process is extremely slow, infiltration is usually almost not determined. Criteria for the diagnosis is the presence of peripheral ridge of the nodules, the absence of ulceration, wet, very slow benign course, a tendency to partial spontaneous regression of knots with the outcome of atrophy.

There is applied electrosurgical, applications ointment treatment. Squamish cell carcinoma of the skin occurs mainly in the red border of the lips, especially on the bottom, on the penis, vulva; on the rest of the skin it is extremely rare. There are formed smooth, compact sizes to pea nodules, sometimes with papillary growths on the surface, which ulcerate, in which raises crater, sometimes painful ulcer bleeding with a tight bottom, twisted, towering above the edges. The tumor is rapidly increased, destroying the surrounding and underlying tissues, and metastasize. As far as treatment methods are concern there are applied short-distance roentgen therapy in combination with surgical excision and chemotherapy.

Cancerous tumors of the skin take the second place in the structure of oncological morbidity. Among the factors that influence the occurrence of precancerous diseases, cancer and melanoma, the leading place is occupied by ultraviolet irradiation, chemical carcinogens - tar, asphalt, arsenic, radiation exposure, thermal and mechanical trauma.

Skin cancer is divided into basal and squamous. Basal cell skin cancer is 70-75% of cancerous skin tumors. It develops from the appendages of the skin or from the basal layer of the skin epidermis. Clinically the disease is characterized by the appearance of seals in the form of yellow plaque, which slowly increases in size.
