Origins of Cancer

All cancers start from cells the body’s basic unit of life. To understand the cancer it is helpful if you know what happens when normal cells become cancer cells.

The human body is made of many different types of cells. These cells grow and separate in a controlled manner to manufacture more cells since it will help in keeping the body in good condition. When the cells become older or damaged, they die or and are replaced with new cells. However sometimes this process goes wrong. The cells did not die and when they should and new cells that forms in the body does not require them and the extra cells may form a tissue called a tumor. The tumor is classified into two one is Benign tumors and Malignant tumors. Not all tumors cause cancer.
