I asked Dr. Lamm a question re: the Vitamin A levels, and he said (now this is not exact) something to the effect that most (if not all) of the Vitamin C is in the form of beta carotene. Plus, he mentioned the other vitamins in the formula doing something to counter the high levels of Vitamin A. Sorry, the more I read this post, the more I realize I am not giving any definite answer to the question. But, he defended it and it sounded ok to me.
I figure the vitamins won't hurt me. My urologist is familiar with Dr. Lamm's work and suggested I take them also, even after reading about Oncovite from this site. So, I will keep taking them.
And a suggestion, have your local pharmacist order them from their wholesaler or from the company. I have had nothing but trouble getting my vitamins from www.drugstore.com.
Vitamins Don’t Curb Bladder Cancer Risk
ISLAMABAD: A few reports have suggested that certain vitamins protect against bladder cancer. However, new research indicates that the apparent anti-cancer effect disappears after accounting for a person’s smoking history.
In the current study, people with high levels of vitamins in their blood had a low risk of bladder cancer. As it turns out, however, these people were also the ones who rarely, if ever, smoked.
Because smoking is a well-known risk factor for bladder cancer, it was probably their lack of smoking, not the high vitamin levels, that protected these people from cancer.
The results, which are published in The Journal of Urology, are based on a study of 9345 men who had blood samples frozen when the study began and then were followed for more than 20 years to determine the rate of bladder cancer.
During the study period, 111 men developed bladder cancer. The stored blood samples from these men and from 111 similar men without cancer were analyzed for several vitamins.
Dr. Abraham M. Y. Nomura, from Kuakini Medical Center in Honolulu, and colleagues found that as blood levels of alpha-carotene, beta-carotene, lutein plus zeaxanthin, beta-cryptoxanthin, and total carotenoids rose, the risk of bladder cancer decreased.
However, after accounting for how much a person smoked, none of the vitamin levels had much of an effect on bladder cancer risk, the team found.
