Can you donate blood if you have had cancer?
I had tongue cancer three years ago.
Potentially. You can check out the following for guidelines for complete details...http://www.cancer.org/Treatment/TreatmentsandSideEffects/TreatmentTypes/BloodProductDonationandTransfusion/blood-product-donation-and-transfusion-blood-donation-by-cancer-survivors
I think you would have to talk to the people doing the blood work
Check with your doc next time you make an appointment
