Overview of Early Skin Cancer

Skin cancer is one of the common malignant tumors, among which basal cell carcinoma and squamous cell carcinoma are the most common. Squamous cell carcinoma is more malignant and often occurs in the skin, mucous membranes and the junction of skin and mucous membranes in the head, neck, limbs, trunk and other parts. Ulcers can form in the early stage and grow invasively.

Common types of skin cancer include squamous cell carcinoma and basal cell carcinoma. Squamous cell carcinoma is highly malignant and often occurs in the skin, mucous membranes and the junction of skin and mucous membranes in the head, neck, limbs, trunk and other parts. Ulcers can form in the early stage and grow in an invasive manner. When it penetrates into deep tissues, it is often accompanied by purulent infection and lymph node metastasis.

It is easy to evolve on the basis of xeroderma pigmentosum and senile keratosis. Basal cell carcinoma is more common in the elderly, and is prone to occur in the forehead, eye sockets, eyelids, nose, and around the ears. It is less malignant and grows very slowly. It is very common for the course of the disease to exceed 10 to 20 years. At the beginning, it is mostly a small thickened piece, which gradually bulges and infiltrates around it, and rarely metastasizes. Skin cancer accounts for about 1.5% of all malignant tumors in my country, and the incidence rate in the south is higher than that in the north.
