How uncomfortable is the first mammogram after lumpectomy?

Similar to Pre-Op: Following a lumpectomy for breast cancer, we usually wait 6 months before getting a follow-up mammogram. By then, most of the healing has taken place and the mammogram is not too different than preop. Rarely, a mammogram is ordered soon after surgery, but the techs know to be very gentle under these circumstances.

DON'T KNOW: It varies from person to person, one tip that has worked well with my patients is to take Ibuprofen (motrin) 200 ~ 600 mg, 30 min ~ 1hr before the mammogram.

Depends on : how soon after the lumpectomy, and the extent of the surgery. If everything is healed, it probably won't feel any more uncomfortable than it did before.
