Hello to you! I am sorry to hear about your mom’s diagnosis. I will tell you my experience. I’m am now 64. When I was 60, I noticed tiny lump on the margin of my eyelid. I had sought medical help, 3 different medical providers didn’t think it was anything to sort about. A few months later it started to change and grow, so I had it biopsied and it was merkel cell cancer. This was December of 2019. In my research, I found out that it was quite rare and aggressive. My treatment was all done through Mayo Clinic in Rochester. They started by doing a blood test to see if I had made antibodies to the cancer. They also did a full body PeT CT to look for any cancer, which was negative. They tested my eye and face to see if cancer was present in my lymph nodes, which was negative. So the plan was: I had it surgically removed, which also removed about 9 mm of my eyelid, the cyst was only 3 mm wide, followed by 25 treatments of radiation to the eye lid and surrounding area, using proton beam. During 2021 and 2022 I had full checkups every three months. PeT CT, blood work and exams. I have been Merkel cell free since the radiation, but my dermatologist found melanoma on my arm in 2022 and had then I had it surgically removed. It had not spread so no more treatment necessary. I check my skin often now for changes and do not get direct sun exposure. I use sunscreen and hats! We love the outdoors, hiking and exploring so I still get outside but keep covered! All my providers at Mayo have been excellent!
