@s2vera: Funny you mentioned the analogy to Freddy Kruger - I say that, too, about my melanoma as my one metastatic lung nodule responded early on in immunotherapy treatment but I've joked that I feel it could be lurking somewhere else inside like Freddy! But I've adapted Mark Twain's philosophy about worrying: "I've had a lot of worries in my life, most of which never happened"! Which is not to say I don't have questions and plans, I do. But I'm trying to let life unfold and be open to it. It was a process, I admit.

I've no doubt having experienced the losses of your sons have contributed to some sense of hypervigilence and increased awareness but I'm wondering if those concerns about skin cancer may be misplaced or exagerated for your own situation now. Had anyone actually said that it was your mother's sebhorrheic keratosis that directly led to the SCC? That would be highly unusual. One need not expose themselves to the sun excessively to be susceptible to developing a skin cancer, especially those of us who are fair skinned with light eyes due to less melanin to help protect against normal, every day UV rays. Taking standard precautions as we've all been taught now help to lessen exposure considerably from "days of yore" when these facts were not known.

Has your therapist been helpful in addressing some of these health concerns?
