Chemo and bone loss questions
My questions are how often and how badly do chemo-therapies lead to bone loss, thinning, osteopnia and ultimately osteoporosis?
Today I was handed a copy of a bone density scan recently done on me that shows moderately severe osteopenia of my thigh bones (T scores of -2.1 and -1.7) . Two years ago the T scores were normal but since then I have undergone 6 rounds of Taxotere and Carboplatin. Now I know those drugs did a number on my bone marrow, since my complete blood counts were in the tank after the chemo was completed 4 months ago, but I was surprised to see such a dramatic impact on my bone density. I have been taking vitamin D3 supplements even before the chemo started and I have now started supplementing with calcium. So I am wondering if I should expect the bone loss to get more pronounced and when does Boniva, Fosamax, etc. start to be indicated for cancer patients having received chemo.
