Cancer epithelioma

Cancer epithelioma is a type of cancer of the epithelial cells, which are the cells that line the outer surfaces and internal organs of the body. It is generally classified as either non-melanoma or melanoma, depending on the type of cell affected. Non-melanoma cancers can include squamous cell carcinoma, which usually affects the skin, and adenocarcinoma, which is commonly found in the lining of the digestive tract. Melanoma is a type of skin cancer that originates in the melanocytes, the cells that produce the pigment melanin. Most epitheliomas begin in the inner lining of organs, such as the lungs, breasts, ovaries, and colon. They can spread to other organs and tissues, including lymph nodes. The most common symptoms of epithelioma include a lump or mass, changes in skin color or texture, a sore that does not heal, itching, and pain. Diagnosis is usually done through physical examination, imaging tests, and tissue biopsy. Treatment of epithelioma depends on the type, stage, and location of the cancer. Surgery, radiation therapy, chemotherapy, and immunotherapy are common treatments. For some types of epithelioma, targeted therapies, such as immunotherapy and targeted drug therapy, may be used. Prognosis is highly variable, depending on the type and stage of the cancer. Early detection and prompt treatment can improve outcomes.
