Maria,
There is an awfull amount of research papers on L-arginine & almost all I read (not so many) appear to show positive results for various diseases including cancer.
However there is a small possibility that it may be a double edge supplement. I remembered buying many years ago a nutrition bar formulated by a cardiologist to improve the function of weakened hearts. These bars contained L-Arginine & the pamphlet issued by the MD warned they were not indicated for cancer patients since one of the ways in which they were supposed to help was in increasing capillary bloodstreams in the heart muscle.

I tried to find more recent info on the possibility that L-Arginine might be promoting angiogenesis which would be bad for cancer patients. My very brief search led to this:

http://www.pubmedcentral.nih.gov/art...3750&tools=bot
Production of angiogenic activity by human monocytes requires an L-arginine/nitric oxide-synthase-dependent effector mechanism.
But I am not qualified to pass judgement on how significant this research paper is versus many others which show antiproliferative modes of action against cancer cells.

It would be better to ask the advice of an expert to clear up the possible ambiguity.
