I am stage 1B and have never had a scan, besides a lung x-ray before my WLE was done in 10/09.

From what I understand LDH levels are not good for determining if the mel has just slightly progressed into a small tumor, but if the LDH levels are off it means that mel has progressed greatly and you would be feeling other effects from it. I wish there was a “blood test” for melanoma. Hoping in the future!
