The best I can say is not yet. Ultra sound shows "Hypervascular indeterminate mass measuring 0.7 x 2.8 x 2.3 cm in the left anterior forearm. Vascular malformation is a possibility." The waiting for MRI with contrast and marker seems forever--but is scheduled for Jan 3. On the other hand, maybe it is better to get through the holidays before I find out any news. Thanks for asking. (My experience with PET scan was for a tumor in the lung, which once upper left full lobectomy was performed, no chemo or radiation needed.)
