Any updates? While many husbands can look like idiots to us, we must remember they too are scared. Sometimes their way to cope when they can't fix the problem is to run and hide, bury their head, and focus on "you" being the neurotic one. My dear friend is going through BC right now and we've had that conversation more than once. And that behavior is not limited to men, my aunt is the same way. She refuses to acknowledge that there could be an issue, she minimizes it, and just does not want to know any more about
it until the time.
It may not help with the support you need, we'll help you with that and can offer suggestions, but I do think your husband cares and is worried if you are, but just can't show it. I like to read and be informed but others prefer to stand back and wait. Others are somewhere in the middle.
Remember that while the mammogram can be showing trouble, most likely it is a big nothing. Please follow up with the doctors, be your own best advocate and let us know how it turns out.
