Exact Sciences/Mayo study shows promise

A study from Madison-based Exact Sciences Corp. and Mayo Clinic and released by the American Association of Cancer Research shows promise for the development of a blood-based lung cancer test.

A multiround study of nearly 400 patients has demonstrated high accuracy for detecting lung cancer at all stages.

Lung cancer is the leading cause of cancer mortality, resulting in 1.7 million deaths globally and more than 150,000 deaths in the United States every year. Most symptoms occur in the late stages of the disease when the survival rate is only four percent. More studies are needed.
