About a week back, the Unknown Son had a CT scan that showed some suspicious spots in his right lung. He had his biopsy today.
Unfortunately, the news wasn't good. His cancer (Wilms Tumor) has recurred. According to the surgeon, there was at least one clear tumor (pea-sized) in his right lung, and clear evidence that it had also metastasized into some of the lymph nodes. I'm currently in the ICU with him as he recovers from the biopsy, and I'll spend the night (the Unknown Mom will take over tomorrow).
He's awake and in good spirits. Looks like we'll be watching Sponge Bob DVDs for a while longer, followed (hopefully) by sleep).
I'll post more information as I get it.
update: It's the morning after, and he's doing well - his fever has broken, he's talking up a storm, getting all the tubes out except for his chest drainage tube, and about to start drinking fluids on his own.
