But remember one is a cancer the other one is a precursor of cancer. So it has long term health implications for health insurance etc. ...Read more

What is the survival rate with melanoma in situ stage 1?

If the nodes are enlarged due to reaction to surgery (or infection), then they will settle down and decrease in size in 4-6 weeks. So keep an eye and check the size of the node once weekly and see if they decrease or increase. ...Read more
