According to Eduardo Faure (thyroid cancer specialist, but not Kirchner's doctor) the papillary carcinoma diagnosis was a 'false positive', which can happen occasionally:
"The cells may originally appear to be cancer but in 2 percent of cases, after the operation, when a more thorough examination can be performed, it turns out they are not," the doctor said in an interview.
I'm glad it turned out that Fernandez de Kirchner never had cancer, and I'm sure so is she, but I'd be pretty pissed off if some misinformed doctors had removed my thyroid for no compelling reason, especially in light of the fact that the effects of being thyroid-less are not much fun. As expected the Argentine people are also pretty darn ecstatic that the popular lefty leader never had cancer. News of her upgraded 'cancer-free' diagnosis, by spokesman Alfredo Scoccimaro, was greeted with great jubilation by some fans who had kept vigil by the hospital throughout her ordeal.
But I have to wonder how idiot-boy Hugo Chavez feels about this new 'no cancer for Kirchner' status update. I wonder if he's bummed out. After all, Chavez was convinced that the U.S. was probably behind the rash of cancerous diseases besetting so many Latin leftist leaders, including his own and Kirchner's. Now he has to scratch one off his list. I'd like to think he was alone in his lunatic thinking, but there are many equally delusional folk (see comments) who also entertained the notion that the U.S. has nothing better to do than give people cancer. If that's the case, Ahmadinejad and others would be long gone.
