As I wrote before, I myself HAD breast cancer and conceivably could still have it growing somewhere in my body, including bones. That has to do with metastasis, the spread of an original cancer to other places. So a few months ago I asked if this was a concern.

If you have a family history, and then get breast cancer while on Tymlos, you would probably get cancer only in your breast, not your bones. It isn't even relevant.

As I wrote elsewhere, the rats in the study had huge doses for a long time. I believe Forteo's black box warning was recently removed and so was the time limit- because NOONE got bone cancer from it. Tymlos is very similar. The black box warning will probably be removed from that too but it is newer than Forteo and a certain amount of time needs to go by before the time limit is removed and the black box warning as well.

This is not a realistic worry, based on family history. As a cancer patient, I am not worried nor are my doctors.
