I'm not convinced about Castle Testing. I had it performed back in early 2020 on an amelanotic lesion that was melanoma requiring surgery. The test results came back as 1A: low chance of recurrence/metastasis. Well, four years later and it metastasized, which is why I'm here now. I think because it was done so soon after approval I was never billed for it, but repeatedly asked if I wanted to give a charitable contribution to the company.
