This method would now look deep into the basis of a genetic strand and see the cells that are healthy and affected by cancer to see its growth. Cancer cells are often confined to a certain area it chooses and remains there to infect the cells as it devises for its next phase or move to do, in harming the human body. Doctors fear the process cancer cells do called "metastasizing," a process wherein it spreads its chaos to other parts of the body, fast-tracking the infection to different parts and forms of cancer.
