Cancer is divided into four stages based on where it has occurred and how much it has grown. The method of treatment is also done accordingly. The sooner this disease is detected, the greater is the possibility of recovery. However, sometimes even after treating cancer, its cells can remain in the body and emerge again. This is because it is very difficult to eliminate them completely.

Why do cancer cells remain in the body despite treatment?
