It was not fun, but was necessary. The doc must have taken seven or eight tissue samples, and I could feel each incision. Afterward I felt weak and light headed but was able to walk home; on the way I stopped at the Park Slope Sweet Melissa Patisserie on Seventh Avenue and got a chocolate chip cookie (very rich and very sweet) to raise my diminished blood sugar level. I should get the results of the biopsy in a week. The ultrasound showed calcium deposits which would be the likely explanation for my elevated PSA should the results turn out to be negative. It would also confirm my hunch that I should switch from dairy to soy milk/yogurt.
