WOODBURY - Scientists have found a way to shift your immune system from defense to offense to fight cancer.

The treatment involves removing white blood cells from patients, genetically modifying the cells to target cancer, and putting them back into the body.

Scientists say the process lowers cancer's ability to shield itself from the body's natural immune system.

Researchers say that early trials have shown promising results, with many patients showing no symptoms after treatment. However, experts say they still need to conduct more studies.
