Over 13% of the total worlds population die from cancer and yet many of us don’t know what exactly cancer is. Cancer is a collection of diseases where cells are constantly growing and dividing way beyond the limits which could be stated as normal (these cell are called aggressive cells), cells could also start destroying tissues next to them (known as invasive cells) or start spreading over to other parts of the body (know as metastatic cells).

Over the years after a lot of research, various treatments have been discovered by the scientists and many treatments are still on experimental basis. These treatments differ according to the cancer stage and the general state of the patient. To state a few treatments would be surgery, monoclonal antibody therapy, radiation therapy, immunotherapy, chemotherapy or other methods.

The aim of these cancer treatments is to remove the cancer from the affected part of the body without damaging the other parts. At time surgery could achieve this, but as we stated the properties of cancer cells earlier which are aggressive, invasive and metastatic often reduces the effectiveness of surgery. All treatments have their pros and cons, but the doctors always aim to eliminate this disease by choosing the appropriate treatment.
