Research Reveals How Aspirin May Slow Cancer's Spread

New research reveals how aspirin and other anti-inflammatory medications might slow the spread of cancer.

Although this effect has been known by scientists, the biological mechanisms were not understood, Fox News reported Tuesday. The breakthrough research, reported in the Feb. 14 issue of Cancer Cell, was conducted by experts at the Peter MacCallum Cancer Centre in Melbourne, Australia.

Study co-author Tara Karnezis told Fox News that tumors secret proteins and compounds called growth factors, which draw blood and lymphatic vessels to the tumor that enable its spread.

"But a group of drugs reverse the widening of the supply line and make it hard for the tumor to spread -- at the end of the day that's what kills people," Karnezis told Fox News. "This discovery unlocks a range of potentially powerful new therapies to target this pathway in lymphatic vessels, effectively tightening a tumor's supply lines and restricting the transport of cancer cells to the rest of the body."
