I don't think Vit. C causes cancer but can it exacerbate symptoms of metal toxicity in anyone including cancer patients? I have read it can be used to protect against cancer but I have also read that it could cause it to be worse. That doesn't really make sense to me though.

Vit.c Contraindications, Carcinogenicity & Mutagenicity

LudicrousFor the truthhttp://lpi.oregonstate.edu/f-w01/cancer.html

Vitamin C Doesn't Cause Cancer!The study was conducted in a test tube (in vitro) under conditions far different from the infinitely more complex conditions in cells and tissues of the human body (in vivo). http://www.cancermonthly.com/blog/2007/12/vitamin-c-and-cancer.html

Vitamin C and CancerPerhaps our health authorities will recognize the benefit of this “mere” vitamin. But, maybe the issue all along was not the fact that vitamin C is an effective and non-toxic therapy, but rather that drug companies cannot make millions of dollars from it because as a vitamin it is difficult to patent. If this is the case, it would be another example of how economics not medicine decides what therapies are made available for cancer. http://www.vitamincfoundation.org/vitcancer.htmhttp://jdc325.wordpress.com/2008/10/31/vitamin-c-causes-cancer/

Vit.c Contraindications, Carcinogenicity & Mutagenicity 4.3 Contraindications

Ascorbic acid is contraindicated in patients with hyperoxaluria (Dollery, 1991) and G-6-PD deficiency Does anyone know what G-6-PD deficiency is? Is it a liver enzyme? 7.3 Carcinogenicity It has been reported that there is no evidence of carcinogenicity (Dollery, 1991). However, some studies suggest that vitamin C may amplify the carcinogenic effect of other agents. Scwartz et al. (1993) report that L-ascorbic acid increases the oral carcinoma size induced by dimethylbenz(a)anthracene. Also, butylated hydroxyanisole induced forestomach carcinogenesis in rats (Shibata et al., 1993) and the K2CO3 induced promotion of bladder carcinogenesis in rats (Fukushima et al., 1991) were both amplified by the administration of ascorbic acid. Vit. C may amplify carcinogenesis. .5 Mutagenicity Ascorbic acid is reported to increase the rate of mutagenesis in cultured cells but this only occurs in cultures with elevated levels of Cu2+ or Fe2+ . This effect may be due to the ascorbate induced generation of oxygen-derived free radicals. However, there is no evidence of ascorbate induced mutagenesis in vivo (Diplock, 1995). Here it says that Vit. C can increase mutagenesis in those with elevated levels of copper or iron. Don't most autistics have copper overload? http://www.inchem.org/documents/pims/pharm/ascorbic.htm
