So which vitamins and supplements are BAD for cancer?

[Guest guest]

I've come up with a few:

GABA: can be used as a natural pain reliever, but may be very bad for

some cancers, especially colon and ovarian cancer.

Synthetic folic acid: may be bad for colon cancer

Copper: Seems to be a primary player in angiogenesis.

Iron: Most of us should know by now that cancer cells have a hunger

for extra iron. E.g., leukemia and colon cancer have 1000x the iron of

normal cells. So taking extra iron would seem like a bad thing to do

if you have cancer.

Mega doses of C seem to actually be bad for some people with cancer,

help others, and be neutral for still others. There were some threads

several months back about this topic. It can come as a real shocker to

some that mega C may be bad for some cancer patients. But what

is " mega " ? 100 grams a day? 50? 10? 5? Just 2? And which cancers

respond positively, neutrally, and negatively to vitamin C?

It is not my intention to start a feud, and I won't. But some

viewpoints, such as Budwig and Dr. Lorraine Day, for example, say all

(or most) synthetic vitamins are bad, for a number of reasons. But are

they really bad, or at the worst a waste of money? One naturopath I

visited said at worst taking too many of most vitamins was just a waste

of money, but wouldn't do any harm. (With the exceptions of those

supplements well known to be toxic past certain doses).

I have read one (and just one) article that showed that vitamins C and

E interfered with the cancer fighting abilities of the omega 3 oils DHA

and EPA. However, the article had two groups of cells under study --

one in which NEITHER C or E was given, and the other in which both C

AND E was given. The authors of the article then erroneously claimed

that antioxidants would interfere with EPA and DHA, when in reality,

what they had shown was that possibly C or E or both would interfere.

-according to this research, vitamin e succinate is beneficial,,,

Vitamin E succinate inhibits colon cancer liver metastases.

Barnett KT, Fokum FD, Malafa MP.

Medicine, Springfield 62794, USA.

BACKGROUND: Vitamin E succinate (VES) is a promising anti-cancer

micronutrient. In this study, we tested the hypothesis that VES will

promote colon cancer tumor dormancy and inhibit liver metastases in

colon cancer. METHODS: CT-26 colon cancer cells were treated with VES

in vitro and in an in vivo model of liver metastases. The impact of

VES on cellular proliferation and apoptosis was measured in vitro by

MTS assay and sandwich ELISA and in vivo by PCNA staining and TUNEL

assay, respectively. Correlation coefficients and independent t tests

were used for statistical analysis. RESULTS: VES significantly and

specifically inhibited cell proliferation (P = 0.011) and promoted

apoptosis (P < 0.0074) of cancer cells in vitro. VES produced a 40%

reduction of liver metastases (P = 0.037). Five of the eight mice had

an excellent response to VES. Subsequent analysis of these five mice

revealed a 75% reduction in the number of liver metastases (P <

0.05). VES significantly promoted tumor cell apoptosis (P < 0.0003)

and inhibited cell proliferation (P = 0.0069) in vivo. CONCLUSIONS:

VES inhibits the growth of colon cancer cells in vitro and in vivo.

This is the first report of VES inhibition of colon cancer tumor

metastases. The mechanism of VES anti-tumor and anti-metastatic

activity in vivo appears to involve promotion of tumor apoptosis and

inhibition of cell proliferation. These findings support further

investigation of VES as a micronutrient to promote colon cancer tumor

dormancy and prevent metastases.
