<p>cangel, at what age would one suspect the cause of a melanoma to be genetic in origin vs. of environmental origin? For example, if one is first diagnosed with a melanoma at age 65 is that environmentally caused, or is there a genetic component? What about if it were first diagnosed at 60, or 58, etc.? How about 70? Also, what is the increased risk to children of the patient, or to grandchildren? Significant increased risk, or not?</p>
<p>Also, I have been told that one can get a melanoma internally as well and it can’t be seen. Is this true, and where would one find melanomas internally?</p>
