Cancer Blood Test

New Push to Develop Cancer Blood Test – Researchers have announced plans to develop a blood test that can detect a cancer cell that has been shed from a tumor.

A blood test so sensitive that it can spot a single cancer cell lurking among a billion healthy ones is moving a step closer to being on the market.

A test that can capture such cells has the potential to transform care for many types of cancer, especially breast, prostate, colon and lung.

“This is like a liquid biopsy” that avoids painful tissue sampling 

Dr. Daniel Haber, chief of Massachusetts General Hospital’s cancer center and one of the test’s inventors and health care giant Johnson & Johnson.

Prostate Test Found to Save Few Lives
