Does Drinking Alcohol Impair The Growth Of Stem Cells?

I have recurrent Non-Hodgkin diffused large b cell lymphoma stage 4.
This week we tried to harvest my stem cells for a transplant, but got less than half million cells. The plan now is to rest for 2 weeks and try the harvesting again.
My question is.... Does drinking alcohol impair the growth of the stem cells that we are trying to collect?

Thanks, Betty Dilbeck
