For esophagus cancer, the test results are looking positive. Eating more curry may not help because the turmeric loses its cancer fighting qualities but could be introduced as a key component in the fight.
McKenna said the study showed curcumin caused the cancer cells to die "using an unexpected system of cell messages."
Normally, faulty cells die by committing programed suicide, or apoptosis, which occurs when proteins called caspases are 'switched on' in cells, the researchers said.
But these cells showed no evidence of suicide, and the addition of a molecule that inhibits caspases and stops this "switch being flicked' made no difference to the number of cells that died, suggesting curcumin attacked the cancer cells using an alternative cell signaling system.
