Eoplasms are call malignant. By the way, the more common term “cancer” refers only to epithelial malignant neoplasms. And does not cover the entire huge group of tumor diseases. There are two types of neoplasms – benign and malignant. type of growth. Benign ones grow slowly and only compress the surrounding tissues. Malignant cells penetrate into neighboring structures and destroy them. That is, metastasis occurs – the entry of malignant cells into other organs in. Different ways and the development of secondary formations.
The main differences between them
Malignant cells are always broken” genetically. Their Argentina Mobile Number List properties are directly relat to mutations in DNA that affect their reproduction, growth and mechanisms of recovery – repair – of the cell genome. The main genes that and tumor growth suppressors. For example, mutat proto-oncogenes can trigger the process of abnormal, very rapid and uncontroll division of damag cells and malignant growth. And the mutation and loss of function of tumor suppressor genes, which help detect DNA damage and start the process of destroying the “wrong” cell, can lead to the development of a malignant tumor. In addition to DNA damage, the development of the disease is influenc by external factors.
Which cell division is accelerat
Viruses for example hepatitis B and C viruses USA CFO some strains of human papillomavirus, HIV, some types of herpes viruses), bacteria, for example, Helicobacter pylori, parasites, radiation, drugs (mainly , hormonal), nutrition, lifestyle and much more. An important role is play by chronic inflammation and organ damage, due to. A “broken” cell does not work according to the rules of the body: it begins to divide abnormally quickly and uncontrollably, not responding to signals and not self-destructing, as it happens normally with cellular breakdowns. A malignant tumor arises and grows, which disrupts the function of the organ and metastasizes with lymph, blood and other routes to different organs.
