I've also received many emails about Exact Sciences ( EXAS - Get Report), including this one from Andre L.: "I've enjoyed your work over the years. I had a question on Exact Sciences. It originally caught my eye when Odette Galli, your former colleague, wrote about it as an alternative to colonoscopy. "It's been a long road and it looked like the Pregen-Plus test was about to be included in the Ameircan Cancer Society guidelines, which meant that the insurance companies would reimburse patients (i.e., pay Exact). Now the FDA seems to have sent a warning letter about this "device" and about some additional steps that Exact may have to jump through. What's your take on this whole situation?"
