Thanks, Dr. Besides his death, which saddens me, I appreciate the info on Merkel Cell. My head, shoulders and back are cancer factories. I see my dermatologist every 3 to 4 months. And am actually nursing 12 stitches due to a MOHs procedure on my scalp for squamous cells. I'm familiar with Melanoma but hadn't heard about Merkel Cell until yesterday. I'll keep an eye out. Thanks for the update.
