Key result
Physiological mechanical stimuli from the beating heart act as an intrinsic anticancer mechanism by inhibiting cancer cell proliferation.
Why the study?
Do mechanical forces of the beating heart suppress cancer growth?

The mechanical forces of the beating heart may act as an intrinsic anticancer mechanism, explaining the rarity of primary cardiac tumors and metastases.
The cardiac vasculature is characterized by high pressure, high blood flow, and dense vascular branching, which may increase its exposure to circulating tumor cells (CTCs). However, both primary cardiac tumors and metastases are remarkably rare. This mechanism has remained poorly understood. A recent report by Ciucci and co-workers 1 show that mechanical load in the heart inhibits cancer cell proliferation. Their work proposes that physiological mechanical stimuli is not merely a regulator of cancer progression, but also an intrinsic anticancer mechanism.
