Red cells

Hi all hope you are all doing as good as you can .
I have had low blood counts for almost a year,they have put a tube every where they can put one. Every thing comes back clean Now they want to do a bone scan . I was fine untill I did the chemo . What if they find the bone marrow is not producing red cells then what???
I had a lung removed in 2006 two years May 3rd.
Have any of you had this problem?????
