Hi An:
Sorry for your angst and the performance of the doctors doesn't help! In any case, I'll share some thoughts on your issues. First of all, and coincidentally, I just had a basal cell skin cancer removed yesterday. It was found during a routine dermatology visit two weeks ago...body inspection, found something peculiar, cut it off for biopsy and called two days later telling me basal cell skin cancer. The protocol here then is to come in for out patient surgery where they cut a little deeper to make sure they get the margins. It was no big deal, took about 1/2 hour...now I have 10 stitches and am moving on with life.
There is a high probability that there is NO connection between your husband's PCA and his skin cancer. I have the fair Northern European skin also and (probably like your husband) got way too much sun as a kid. That is a sure recipe for skin cancer but, fortunately, it is usually no big deal. Hopefully his pathology will come back as basal cell but as long as it's not melanoma or some strange variety you shouldn't be too worried.
As far as the question as to which to take care of first, I think it depends on what your dermatogist says about the pathology. If it's basal cell then he probably has had it for some time and a few more months probably won't matter, i.e. take care of the PCa first. However, if you get a feel that the skin cancer is somewhat aggressive then I suggest you get that handled first. As we have discussed before, you husband's PCA stats suggest slow growing (if not indolent) cancer so a short delay in treating the PCa is not likely to hurt. I guess the thing I don't suggest is taking care of both cancers at the same time. From what I know about what CAN happen post surgery for PCa I think you want to be focused totally on that recovery for a few months.
In any case, I'll pray that the skin cancer is a mild sort and I wish you the best.
