A recent study has revealed that an aspirin a day may stop cancer from spreading. In 2025, over 2 million new cancer cases are expected in the U.S., with more than 618,000 deaths—about 1,700 per day—according to the American Cancer Society. The research, conducted by scientists at the University of Cambridge in England, discovered the common drug could reduce metastasis—the spread of cancer cells from the original tumor to other parts of the body—by stimulating the immune system.
