A malignant tumour arising from epithelial cells, which are cells lining the external or internal surfaces of the body Carcinomas spread to nearby tissues They may also spread to distant sites such as lung, liver, lymph nodes and bone See also metastasis
form of cancer that develops in tissues covering the external or internal surfaces such as the lung
any malignant tumor derived from epithelial tissue; one of the four major types of cancer
a malignant tumor of the epithelial cells that line body surfaces and cavities Carcinoma in situ (CIS) refers to an early stage of cancer that has not invaded surrounding tissues
a malignant tumor that arises from epithelium, found in skin and the lining of body organs; for example, breast, prostate, lung, stomach or bowel Carcinomas tend to infiltrate into adjacent tissue and spread (metastasize) to distant organs, such as bone, liver, lung, or the brain
form of cancer that develops in tissues covering or lining organs such as the lung
{i} BCC, common form of skin cancer malignant tumor (usually doesn't metastasizes) in which the cancer cells look like the basal cells of the epidermis and is found on the face and neck where the skin is exposed to ultraviolet sunlight (it appears as a bleeding or scabbing sore that does not heal)
or hypernephroma Malignant tumour of the cells that cover and line the kidney. It usually affects persons over age 50 who have vascular disorders of the kidneys. It seldom causes pain, unless it is advanced. It may metastasize to other organs (e.g., lungs, liver, brain, bone) and go unrecognized until these secondary tumours cause symptoms. Blood can appear in the urine early on but is painless and usually disregarded. Even when the cancer is in the early stages, X-ray films can show deformity in kidney structures
