Help. Can anyone tell me what "insufficient cellularity" means?

[Puzzle]

Does that just mean there were not enough cells in the biopsy to do a diagnosis?

1. That sounds right

Or the right types of sample. Usually you would hear one say insufficient sample for diagnosis but I think you are probably right.
Edit: You are right I looked it up..It means during the aspiration (removal for biopsy of cells) they weren't able to get enough cells out to make a diagnosis.
