Genetic abnormalities in cancer...

Genetic abnormalities in cancer are usually two major groups of genes. -- The promotion of cancer oncogenes are often activated in cancer cells, the cells, the new properties, such as Hyperactivities growth and the division which provide protection against the programmed death of cells, loss of respect for normal tissue boundaries, and Ability to communicate in several tissue environments. Genoa Eliminatory the tumor often is inactivated in the cancer cells, making the loss of these functions in normal cells, such as the replication of DNA precise control over the cell cycle, the direction and responsibility in tissue, and the interaction with the cells of the immune system.

The cancer is usually determined according to the substance from which the cancer stem cells, the primary tumor, and the type of normal cell, as it continue. That is the situation and histology, respectively. A definitive diagnosis usually requires the histological examination of a biopsy tissue sample from a pathologist, although the first indication of malignant tumors can be symptoms or abnormalities gerent imaging. Most types of cancer can be treated and some cured, depending on the type, location and step. Once diagnosed, the cancer is usually contracts with a combination of surgery, chemotherapy and radiation therapy. As far as research is developing treatments are increasingly for the various types of cancer. There was considerable progress in the development of targeted therapy of medicines which are specific to the molecular abnormalities in certain tumors detectable, and to minimize the damage to normal cells. The prognosis of patients with cancer is the most influenced by the type of cancer, and on the stage or the extent of the disease. In addition, the histological classification and the presence of certain molecular markers might also be useful to the forecast, and in the determination of the individual treatments.
