Gregory Sorensen, the CEO of Siemens Healthcare North America opened the session by challenging the notion that screening drives overdiagnosis.
“We’re not over diagnosing,” he said. “We’re over treating.”
Sorensen used as an example, mammography. When doctors find a “low-grade” tumor like DCIS (ductal carcinoma in situ), they may resort to a lumpectomy or chemotherapy despite questions about the efficacy of those treatments, he explained.
“This in turn leads us to question the value the mammography, because it leads to overtreatment. It is not the mammogram that’s the problem,” Sorensen asserted. “It’s the [healthcare] system’s lack of discipline.”
