Cells are tiny and there are billions upon billions of then in our body. If cancer starts to form, how is it that in some cases, treatment can kill every single cell and cure a person of cancer? Isn’t leaving even one cancerous cell dangerous as it’ll multiply infinitely?
In: Biology
The cells in your body are constantly winning wars vs cancer cells. Your body sees cancer cell mutation as foreign and destroys them before they spread. Sometimes some slip through and multiply, in which can spread to parts of the body and start taking over. Radiation helps destroy cancer cells (and normal cells) so eventually the balance can be maintained again.
