Basically, cancer is the change from a cell splitting and number to many uncontrollably. Although the change is reasonable in the body as a process of regeneration of damaged cells are replaced with new ones. However, the control changes the cell no longer functioning normally, then the State is called cancer.
Therefore, cancer is not an infectious disease that occurs because of a bacteria, but rather grow from cells of the organ itself undergoing genetic mutations. The genetic mutation causing the cells to grow abnormally and destructive, i.e. do not follow the rule of law-the law of growth and tend to be destructive.
Cancer can grow anywhere inside the body, including in the throat. However, with the note, not all cancer cells can grow progressively grow elsewhere. This is caused by the immune system (immunity) and also the conditions for growing up in new places not found in the absence of such carcinogens and oxidation by oxidants, such as free radicals.
Just like tumors, cancer has its own clinical characteristics such as the presence of lumps is easy we handle them, weight loss, lack of red blood cells, disorders of the metabolism of carbohydrates, protein and fat. As well, declining taste of soy sauce in a food or drink.
For cancer sufferers, actually support and attention from the family is needed. The attention and support is the sincere can stimulate the hormone work returned to normal later can boost the immune system. Rise of the immunity of the body, means close opportunities for cancer to spread the cells into cells that are still healthy.
However, the treatment of cancer is long-term treatment that cost money and patience without limit, especially when the cancer already reached stage 3 upwards.
