“In cancer, when you treat the patient, initially the tumor will hopefully shrink,” says Banerjee. “The problem comes 5 or 10 years down the road when the disease relapses.”

Cancer has stem cells, or residual cells. They can survive chemotherapy or other cancer treatment and go dormant until conditions in the body are more favorable for them to again reproduce. “When they reappear they can be very aggressive, nasty tumors,” Banerjee says…

“We found aspirin caused these residual cancer cells to lose their self-renewal properties,” says Banerjee. “Basically, they couldn’t grow or reproduce. So there are two parts here. We could give aspirin after chemotherapy to prevent relapse and keep the pressure on, which we saw was effective in both the laboratory and the mouse model, and we could use it preventatively.” …
