I will be starting external radiation for my prostate cancer in a few days.  A friend of mine, who knows that I take many different vitamin supplements, recently told me that he read that you should not take calcium when you have prostate cancer.  Does anyone out there know anything about this?  I've searched the internet and came up with nothing.  I would appreciate feedback.  Thank you!

I remember reading calcium is bad for pca, however vitamin d3 is great.  I believe this is in Dr Snuffy Meyers Book.  My dad is taking high dose vitamin d3.

This is a double edge sword. I HAVE to take calcium supplements. One hude side effect to hormone therapy (Androgen Deprivation Therapy-ADT), my bones will weaken over time. I was instructed to take Viactiv (Vitamin D3 and Calcium), along with prescription Fosamax. This in combination should delay the onset of osteoperosis. I have read that the calcium fro, dairy products shows the possibility of increasing advanced prostate cancer, but I cannot find any control group studies to support it. And once you have advanced prostate cancer, taking calcium supplements is almost nesessary.
