My Grandma has liver cancer and it just spread to her lungs. Doctors told her there is a treatment that has a one in five chance of working, and if it doesn't work, or she doesn't take the drug, she will have one to six months to live.

Is there anything anyone knows that could possibly help her. There has to be something.
Yeah I know it's between her and the "doctor", but obviously when he tells her she only has so much longer to live, there isn't really any other "decision" for her to make. It's not like she chooses to die or live, I came her looking for alternative treatments. And it didn't start in the liver. It was in the colon, then the liver, then the lungs. And she's pretty and doesn't know how to utilize the power of the internet to get better information on her treatments, but instead, is forced to listen to only what her doctor says.
Edit: "and shes pretty old, and doesn't........"

It started in the lungs and spread to the liver. Liver cancer is a secondary disease.

This is between Grandma and her doctors. I know you are worried, but you can't help her with this. She will make the right decision for her self.
