Know Cancer

          Cancer or malignant neoplasms is a disease characterized by typical cell cycle abnormalities that cause the cells' ability to:
• Uncontrolled growth (cell division beyond the normal limits)
• attack the nearby biological tissue.
• migrate to other body tissues through blood circulation or lymphatic system, called metastasis.
 
          Three characters that distinguish this malignant cancer from benign tumors. Most cancers form tumors, but some do not, such as leukemia. Branch of medical science relating to the study, diagnosis, treatment, and prevention of cancer is called Oncology.


          In general, cancer cells form a tumor, except in leukemia. The reaction between acid tetraiodotiroasetat integrin is inhibiting hormone activity of thyroxine and tri-iodotironina which is one of the factors that play a role in angiogenesis and tumor cell proliferation. [2] Uncontrolled growth is caused by damage to DNA, causing mutations in vital genes that control cell division . Some mutations may be required to change normal cells into cancer cells. These mutations are often caused by chemical or physical agents called carcinogens. Mutations can occur spontaneously (obtained) or inherited (germline mutation). Cancer can cause many different symptoms, depending on the location and character of malignancy, and presence or absence of metastasis. The diagnosis usually requires microscopic examination of tissue obtained by biopsy. Once diagnosed, cancer is usually treated with surgery, chemotherapy, or radiation. (Read: Cancer Classification)

          Most cancers cause death. Cancer is one of the leading causes of death in developing countries. Most cancers can be treated and many cured, especially if treatment is started early. Many forms of cancer associated with environmental factors that could have been avoided. Smoking can cause cancer than many other environmental factors. Tumor (Latin: swelling) appoint an abnormal mass of tissue, but can be a "malignant" (cancerous) or "benign" (not cancerous). Only malignant tumors are capable of attacking other networks or metastasize. Cancer can spread through the lymph nodes and blood vessels to other organs. (*)
