How to check for skin cancer at the hospital

Skin cancer is a very common cancer. In recent years, many people do not pay much attention to it, and the incidence of skin cancer has continued to increase. We need to do a good job of skin cancer inspection and identification to facilitate early detection and early treatment. So how to check for skin cancer in the hospital? What are the inspection items?

Skin cancer can occur anywhere on the body. About 80 percent occur on the face, head, and neck, causing disfigurement and danger to the affected area.
1. Biopsy and pathological examination are extremely important for the classification and treatment of skin cancer, and the treatment effects are also different.
Among skin cancers, basal cell carcinoma and squamous cell carcinoma must be differentiated from each other, and they must also be differentiated from seborrheic keratosis, carcinoma in situ, discoid lupus erythematosus, etc.
1. Basal cell carcinoma and squamous cell carcinoma: Basal cell carcinoma mainly occurs on the face, especially the nose, forehead, eyes, cheekbones and upper lip. The lesions develop slowly, and the local area is often not congested. The surface is scabbed without keratinization, the edges are rolled up, waxy and translucent, and there is no or slight inflammatory reaction. Metastasis is rare. Squamous cell carcinoma can occur in any part of the body, especially the junction of skin and mucous membranes and the limbs, lower lip, nose, ears, back of hands and genitals. It often occurs in places with chronic skin lesions. The lesions develop quickly, with obvious local congestion, or dilated capillaries around and on the surface, obvious keratinization, high and hard edges, significant inflammatory reaction, and easy lymph node metastasis.
2. Seborrheic keratosis: Also known as senile warts, it is common in men over 50 years old, mostly on the face, neck, chest, back and back of hands. The lesions are round or oval flat wart-like rashes slightly above the skin, with a yellow, yellow-brown to coal-black color, clear boundaries, soft texture, slightly rough surface, and covered with oily scaly scabs. The number of rashes is uncertain, but often there are many. Seborrheic keratosis can exist permanently without malignant transformation. Individual lesions in a very small number of patients can develop into basal cell carcinoma. Histopathological examination can help with diagnosis.
