Looks like all 3 TV networks led with the story about the US Preventive Services Task Force changing its recommendations on breast cancer screening.
I couldn't watch all 3 simultaneously so I watched the CBS Evening News, which had Dr. Jennifer Ashton report the story.
At the conclusion of the taped segment, she told the CBS viewers that she, as a doctor, would have a difficult time accepting the new recommendations and sharing them with women.
She's entitled to her opinion. But not on a program called the "CBS Evening News." If they want to change it to the "CBS Evening Physicians' Opinion Show" then have at it.
But what she did isn't journalism. It's advocacy and opinion.
Someone at CBS News is responsible for failing to insist that their TV docs aren't told what their role is: take your pick - journalism or medicine.
