Epithelioma
Epithelioma
Epithelioma (pronounced: e-pi-the-li-o-ma) is a type of cancer that originates from the epithelial cells which line the outer surfaces of organs and structures within the body.
Etymology
The term "Epithelioma" is derived from the Greek words "epi" meaning "upon", "thele" meaning "nipple" and "oma" meaning "tumor". It was first used in the mid-19th century to describe tumors that were thought to originate from the epithelial cells.
Types of Epithelioma
There are several types of epithelioma, including:
- Basal cell carcinoma: This is the most common type of skin cancer, and it originates from the basal cells in the skin's lower layer.
- Squamous cell carcinoma: This type of cancer originates from the squamous cells that make up the skin's outer layer.
- Merkel cell carcinoma: This is a rare type of skin cancer that originates from the Merkel cells in the skin.
Symptoms
Symptoms of epithelioma can vary depending on the type and location of the cancer, but they often include changes in the skin such as new growths, sores that do not heal, or changes in existing moles.
Treatment
Treatment for epithelioma typically involves surgery to remove the tumor, followed by radiation therapy or chemotherapy to kill any remaining cancer cells. In some cases, immunotherapy may also be used to boost the body's natural defenses against the cancer.
