Brain Tumour Survivor

What is the benefit of chemotherapy after cancer rather than mistletoe extract? I know you can not get mistletoe extract in the u.s.a. but I am just wondering if that is because the pharmaceutical companies can not make money on it.

Does chemotherapy work in helping to cure liver cancer? How effective is chemotherapy. I know someone who has primary liver cancer (so hasn't spread anywhere in the body) and is about to start chemotherapy in order to shrink the tuma/s on the liver to then remove them surgically. ___________________...
