The War on Cancer refers to the effort to find a cure for cancer by increased research to improve the understanding of cancer biology and the development of more effective cancer treatments, such as targeted drug therapies.. The signing of the National Cancer Act of 1971 by United States president Richard Nixon is generally viewed as the beginning of this effort, though it was not described as a "war" in the legislation itself.
War stated as “a state of usually open and declared armed hostile conflict between states or nations” in Merriam-Webster dictionary. War indicated attack of foreign army.
On the other hand meaning of rebel is opposing or taking arms against a government or ruler. Something has to cause rebellion. There are complaints. These complaints have usually been ignored over so long a period of time that people have become impatient with the slow pace of change; they begin to feel that conditions are unbearable. These complaints are most important causes of rebellion.
I think that cancer cells are rebels (cells live in bad conditions) and they try to live .
We must change our philosophy. We must accept cancer cells as rebels not enemy and we must try to correct bad environment to calm rebels.
