Did You Know What is Cancer? What Causes Cancer?

In our daily life we would often hear about the cancer, there may be friends, companions and also our brother who never had cancer, however, much remains unclear and understand what it was cancer.

It a Cell diseases
For a simple explanation, cancer is the class of diseases associated with cell, a group of cells that can not display its controlled growth (exceeding the normal limits), invasion (intrusion on and destruction of adjacent tissues), and sometimes metastasis (spread to other locations in the body via lymph or blood).

There are more than 100 different types of cancer, and each is classified by type of cell that was originally affected.Almost all types of cancer harm the body when the damaged cells to divide uncontrollably to form a lump or mass of tumor tissue (except in cases of leukemia where the cancer prohibit normal blood function with abnormal cell division in the bloodstream). Tumors can grow and interfere with the digestive system, nerves, and blood circulation, and they can release hormones that alter the function of the body. Tumors that stay in one place and shows limited growth of this type of cancer is generally considered benign.

Cancer cells would be extremely dangerous, or malignant, tumors formed when two things happen:
  • Cancer cells to successfully move the entire body using blood or lymphatic system, destroying healthy tissue in a process called invasion
  • Successful cells divide and grow, forming new blood vessels to feed themselves in a process called angiogenesis.
