Thanks to Dr. David Casper and his staff they took a biopsy of a node on my husband's arm (which for 2 years we have been asking 3 doctors what it is, even though it's gotten larger) and found out it was Stage 3 Malignant Melanoma and had surgery done at Moffitt Cancer Center on March 21, 2014. We owe his life both to our new primary care doctor - Dr. Sara Gitte-Acosta and to Dr. David Casper's office from the PA, him, and testing site.
