Hi Loula! How are you doing today? I get Xgeva (Denosumab) shots every 3 months or so to strengthen my bones. Besides mets from my breast cancer I also have osteoporosis and osteopenia they found when doing my work-up at diagnosis and did a bone density test. I'm not fully understanding all that is accomplished by the Xgeva but I copied this from on-line and maybe it's better than how I could explain it. Xgeva is a brand (trade) name for denosumab. Denosumab is a monoclonal antibody that is used to prevent bone-related events by binding to a protein called RANKL on osteoclasts (the cells that break down bone), inhibiting their formation, function, and survival. This decreases bone breakdown and increases bone density and strength in both the outer layer of bone and the inner spongy layer inside the bone. I hope that helps. I'm not real good at explaining a lot of this medical stuff.
I am just curious as to what type of treatment you receive for Lung Cancer, if you don't mind. I lost my mom to LC way back in 1987. All they had for her at the time was a radioactive isotope they implanted and some outer radiation txts. I hope they've come much further with their treatment options. I wish you all the best!
