Carcinomas are cancers of the what occurrence

What is cancer and the reasons for its occurrence.

squamous cell carcinoma
Carcinoma - a cancer that grow in the epithelial cells of the skin and internal organs. Called the epithelium tissue that protects the surface of the body and the mucous membranes lining the internal organs, as well as most of the cells forming glands.

Cancer can detect any kind of epithelium, such as skin cells, organs (lung, intestine, uterus, breast and prostate, etc.). In the organs of the human body are able to grow simultaneously several different types of carcinomas, for example, can grow on the skin squamous or basal cell carcinoma in the prostate (in particular breast, prostate) - adenocarcinoma and squamous cell carcinoma, etc. All cancers have in common is that the cells of which they are composed are "forgotten skills" of the cells from which they sprung, and acquire the ability to proliferate.
Because of this is the rapid development of tumors with involvement of both the body and the other adjacent and distant organs in which these cells enter the bloodstream and lymph.

Carcinoma, and the causes of its manifestations is not known, but well-studied substances or environmental factors that are able to "run" the process of malignant tumors - is carcinogenic. This is many of the chemicals and some drugs, viruses, ionizing radiation, hormones. As well as genetic predisposition. By acting on the cell, such factors cause the deformation of the structure of its DNA, resulting in cell reborn and gets new features. Carcinoma and its manifestation depends on where it is, its rate of growth and metastasis (the transfer to distant parts of the body). Common signs of this process are the weight loss, anorexia, fatigue, long-term increase in body temperature, lack of blood hemoglobin and red blood cells - anemia or anemia.

Carcinoma has symptoms:
  • changes in voice
  • difficulty swallowing, or the passage of food through the esophagus
