WHY IS HARD TO CURE CANCER


Cancer is not a single diseases it is a name given to a collection of diseases that have common characteristics.


Cancer usually begins when there is a sudden change or mutation in the genes present in our cells. This leads to uncontrolled cell division. Now it is hard cure cancer because every cancer is caused by a different set of genetic mutations.

In different types of cells. Hence it is a different disease each time. Due to which a treatment which works for a individual doesn't necessarily work for the other.


Now cancer cells can be killed with treatments like chemotherapy or radiation. However sometimes this treatments may not kill all the cancer cells risking a cancer relapse. Moreover, such treatments even harm healthy cells of our body.



                                                                                         

Cancer cells can even metastasize, i.e., they can spread to different body parts and start growing there. Thus making it difficult to eradicate cancer completely. In addition to this many cancer are diagnosed at very late stages which makes treatment less likely to succeed. Thus reducing the chances of survival.
