Any growth on an eyelid should be checked by a vet. Those bumps could simply be cysts or tumours. Not worth taking a chance with. Even if it is a tumor, early detection and/or removal makes a big difference. If it's a cyst the vet can lance it and relieve the pressure.
Basically any bump should be checked by a vet. I've sadly seen too many cases every day of pets who's owners 'watched' bumps for weeks or months before they finally brought them in to find out later they were tumors and some had already spread.
Keep us updated on the vets report.
