EPITHELIAL CANCER Meaning and
Definition
-
Epithelial cancer refers to a type of cancer that arises from cells of the epithelial tissue, which is the protective lining found on the surfaces of organs, glands, and body cavities. Epithelial tissue lines the external surface of the body as well as the internal surfaces of organs, blood vessels, and the digestive, respiratory, and urinary tracts. It provides a barrier that protects underlying tissues and organs from injury, infection, and invasion.
When epithelial cells undergo abnormal changes in their growth and division, they can form tumors, giving rise to epithelial cancer. This type of cancer can affect various organs such as the skin, lungs, breasts, prostate, colon, bladder, and pancreas, among others.
Epithelial cancers can manifest in different forms depending on the specific tissue or organ affected. They are classified based on the type of epithelial cell involved, such as squamous cell carcinoma, adenocarcinoma, or transitional cell carcinoma. The risk factors for developing epithelial cancer can include age, exposure to certain chemicals or substances, genetic predisposition, smoking, and exposure to ultraviolet radiation or certain viruses.
Treatment for epithelial cancer typically involves a combination of strategies such as surgery, radiation therapy, chemotherapy, targeted therapy, immunotherapy, or a combination of these options. The choice of treatment depends on various factors including the stage of the cancer, its location, and the overall health of the patient. Regular screenings and early detection play a crucial role in increasing the chances of successful treatment and improved outcomes for individuals with epithelial cancer.

Etymology of EPITHELIAL CANCER
The word "epithelial" originates from the Greek word "epithelium", which refers to the tissues that cover the surfaces of the body such as the skin, inner lining of organs, and the lining of blood vessels. "Epithelium" is composed of two Greek words: "epi" meaning "upon" or "over", and "thelē" meaning "nipple" or "teat". This reflects the fact that the epithelium is a layer of cells that covers and protects the underlying tissues.
The term "cancer" has Latin roots and is derived from the Latin word "cancer", which means "crab". The ancient Greeks observed the finger-like projections of some tumors and thought they resembled a crab, thus gave it this name. This explains the usage of the term "cancer" to describe abnormal growth and spread of cells in medical terms.
