Dont look at those numbers to much i don’t really think they are meant for us patients.. more a way for the doctors to plan a treatment etc.
so many factors count in your case not just how many statistically have died from it..
If an melanoma is under a certain size you don’t usually do SLNB but that doesn’t mean you don’t got it in the nodes. Also some have gotten metastases 15 years after removal of the cancer.
And with pretty fast progress in treatment those numbers they currently got is already old its probebly better now, more melanoma is removed earlier.
