Dr. Cohen mentioned a scan done a few years ago in reference to the cancer being aggressive, i.e., it didn't show up then. If there had been a scan done in May that didn't show this cancer, then it would really be an aggressive form and worthy of note. If there was a scan in May, and it did show cancer, obviously that would beg the question why Rob hadn't received treatment -- I really don't think Dr. Cohen would be party to covering up that kind of information. So I'm thinking that no scan was done in May. However, a colonoscopy could have been done if Rob really did go to spahab and since this cancer is in tissue, not in the colon, I'm guessing it could well have gone undetected.
I didn't get the sense that Dr. Cohen was "covering up" the nodule.
A negative colonoscopy, and persistence pain should have at least promoted a referral and further tests like a CT. So, what can we make of all these pseudo facts? Personally my head is spinning from all the "opinions".
