Gabriel,
You are such a good son.
Here is Dr. Lamm's site discussing the Oncovite issue. Admittedly, this website has a slanted view of Oncovite usage (Dr. Lamm is the creator, developer, researcher and producer of the Oncovite supplement.) However, Dr. Lamm, in my opinion, has been a great advocate of Bladder Cancer patients. Because he has been very responsive to us and our general inquiries, it is my belief that his heart is in the right place and that he is dispensing advice for the true benefit of the Bladder Cancer patient.
My own Urological Surgeon stated the Oncovite issues as being "murky"....
I personally did not use the Oncovite supplement throughout my BCG treatments, however I used a comparable Vitamin/Herbal Supplement of my own choice.
I do not see how it can hurt....

Your father is very lucky to have you for a son.
Your friend,
