Believe me it can - in fact some are so successful that we have to guard against "tumour lysis syndrome" http://en.wikipedia.org/wiki/Tumor_lysis_syndrome
I think the point is to prevent a migraine before it starts. But yes, I know how they feel and they can be crippling.
WOW ! Now you challenge medical treatments that are proven to be effective? Chemotherapy can be taken orally or intravenously. Before making outright dumb comments please, please, please at least attempt to familiarizer yourself with proven scientifically effective forms of cancer therapy. Chemo therapy using differing delivery modes is almost always given to patients following cancer excisions - and yes even us Liberals pray too.
LOL please, please please f your going to call someone dumb you need to have a reason otherwise you end up looking not only dumb, but stupid. I said "I imagine it would be really difficult if not impossible for an oral treatment of any sort to be able to have the same effect as surgery, chemo and radiation. " See that is me saying its unlikely an oral treatment can replace 3 complex things. You even say that chemo is given after surgery so you know cancer treatments are complex. Get it?
Destruction of cancer is not curing cancer, it is another type of removal. It doesnt cure the cancer which exists within the cancerous cells. To cure cancer you'd need to be able to reprogram the DNA of the cancer to stop uncontrolled mitosis (I think thats the right word, havent studied medicine in ages). TLS is about cleaning up the mess left after the forced destruction of the cells. The treatments used in cancer are very harmful to the body but not as bad as having cancer obviously.
