I’m stage 1melanoma, 0.75mm no ulceration 0 mitosis, brisk til. I’m so scared of it turning up in my organs are my chances high or low for metastasis?

Good survival rate. In Stage 1 melanoma the cancer is no more than 2mm thick and might or might not be ulcerated. The cancer has not spread to nearby lymph nodes or to distant sites. The 5-year survival rate is around 97% & the 10-year survival is around 95% according to the American Cancer Society. So if you work with your Oncologist to treat your melanoma your survival rate is very good at this stage.
