"Come clean" is just stupid
First, best wishes for Steve's health. That's what matters.
The article is pretty good but ended badly for two reasons.
"Come clean" assumes Steve has not come clean. Who knows? Is the author an oncologist with some inside knowledge? Why the scepticism?
Further, what does "come clean" mean when you're dealing with cancer? Oncologists deal with probabilities such as "survival at 5 years", cancer-grading, and so on. I'm afraid there is no "clean", at least not in the sense the author demands. Some cancers are 100% lethal, others 100% survivable. Metastatic cancers are not always fatal. This particular one seems to fall somewhere between the extremes.
The cancer has, we hope, not returned but that might not be entirely positive if other factors are bad. The cancer may have returned but likewise that may not be entirely negative. We are dealing with odds relating to the disease, the treatment, the side effects and the individual. A simple tabloid answer either way is not possible.
During treatment there are times when you simply have to wait and see.
So, thanks for news, and the article, but save the accusations and demands for another case and another time.
