What are the types of skin cancer?

There are many types of skin cancer, but we don't need to master all of them. There are some typical ones that we often encounter in life. In this case, we must figure out how to classify skin cancer. So what are the types of skin cancer? Let's talk about the common types of skin cancer.

(I) Basal cell carcinoma. Eighty percent of skin cancers are basal cell carcinomas. If diagnosed early and treated properly, they can be completely cured. According to their histological morphology, they can be divided into the following three types: ① Subepidermal basal cell carcinoma: The surface skin may be intact or accompanied by ulcers. A cyst is formed in the center of the cancer nest, and the cancer cells around the cyst often undergo vacuolar degeneration. Cancer cells may be tubular or glandular in structure, arranged in cords, reticles or islands. ② Superficial ulcerative basal cell carcinoma: It is often multiple, and the cancer nests are in the form of substantial masses, nests or cords, infiltrating from the basal layer to the deep. ③ Basal squamous cell carcinoma: The tumor consists of two components, namely squamous cell carcinoma nests and keratinized beads in the basal cell carcinoma.
(ii) Squamous cell carcinoma. Twenty percent of skin cancers are squamous cell carcinomas. Early treatment is expected to cure them, but the risk of them spreading is quite high. The majority of people who die from skin cancer in the United States each year are due to squamous cell carcinomas. This cancer grows on the trunk and also has a high tendency to metastasize. The cancer cells are papillary, nested, cord-like or glandular structures and can infiltrate the deep dermis or subcutaneous tissue. The cancer cells are divided into four grades according to their degree of differentiation.
