Cancer+Challenge+2

Despite years of research, we have not found a cure for cancer. What is cancer? What makes cancer such a difficult disease to cure? What treatments are available? How do they work? Any promising treatments on the horizon? Who gets treatment? How can we prevent cancer since there is no cure for cancer?

cancer is the disease of the cells--> they ignore signals to die. there DNA is mutated so they are told to die yet they ignore it.

What makes cancer such a difficult disease to cure?

What treatments are available? and how do they work? chemotherapy- poisons the cells ( they damage the DNA) They can't divide. It hurts all the cells that divide quickly. radiation-(spilt atoms falling apart that can shoot out powerful things) that damaged DNA (it can't copy it) ..they aren't able to multiply. usually coupled with surgery (remove a tumor) the wierd thing is that radiation can cause cancer.

New promising treatments:

genentech: focus's on killing off the blood cells in a tumor, so it doesn't have a blood supply and do it dies.
