Cancer can be described as uncontrolled growth in the abnormal cells in one’s body. The growth can occur anywhere in a human body. Cancer builds up when the typical control system of the body stops functioning and as a result old cells fail to die causing new anomalous ones to be developed. The additional cells later form a group of tissue called the tumor. However, some cancers such as leukemia do not form tissues. There are different kinds of cancers in human beings and the fact is that the same cancer type in a person may be totally different from that cancer in another individual. Experts have discovered that within a single type of cancer, say for example lung cancer, there are different sub types with each requiring a unique treatment of its own.
