What is an epithelial tumor?

The epithelial tumor is a cluster of irregularly shaped cells growing specifically on the external membrane of the organ, gland or body part. It may or may not be cancer. The internal and external organs have one or multilayer outer membrane known as the epithelium-nazev, which stems from the Latin prefix "Epi", which means "top". The epitheliums of the ovaries and salivary glands are typical areas where an epithelial tumor can be found. These tumors can also grow in the lining of breast tissue, colon, thyroid and prostate.

If cancer, the epithelial tumor is called cancer. It is the most typical type of cancer. There are six different classes of cancer epithelial tumors. The first is adrenocortical carcinomas that include any epithelial tumor found in the adrenal glands. Since the adrenal glands are responsible for regulating sex hormones such as estrogen, progesterone and testosterone, the epithelial tumor in this gland can cause hormonal implementation and the result of a woman developingSurface male features and a man developing female features.

Deeper voice, more face hair and enlarged breasts can be caused by the adrenal tumors. Tumors that are largely hereditary also lead to cortisol overproduction. Rough epithelial tumors do not respond well to chemotherapy and must be cut, suggesting medical reports. If it is left to grow, this type of epithelial tumor often spreads to the lungs or liver.

The second class of epithelial tumors consists of thyroid tumors. These cancer growth appear on the back of the neck in the thyroid gland. Men are more likely to be affected by this type of tumor. It is usually difficult and can disrupt the function of vocal cords.

Nalopharyngeal carcinomas form the third category of epithelial nodes. Like the thyroid tumor, it is a neck cancer. The general position of these rare growths is the highlight of the pharynx near the nasal duTiny. Melanomas, skin cancer that affect melanin cells are another category of epithelial tumors. All other types of skin cancer form the fifth grade of epithelial tumors; These include spinocellular carcinomas and basal cell carcinomas.

Any other malignant epithelial tumors that are not included above fall into the sixth different classes. This latest category includes Bronchi cancer, cervix and lungs. In this final category Catchall also includes cancer of the colon lining, bladder and salivary glands. While, above all, the risk for adults, more than 1,000 children are diagnosed every year. The most common type of epithelial tumors for adolescents are melanomas, adrenal tumors and thyroid tumors.
