Biomarker may help diagnose lung cancer earlier

(UPI) -- High levels of a protein found in the bloodstreams of lung cancer patients may lead to a method of detecting the disease earlier, and possibly preventing deaths from it, according to a new study. Researchers found high levels of cytoskeleton-associated protein 4, or CKAP4, in the blood of cancer patients predicted their disease. The research was published Tuesday in the American Journal of Pathology. Lung cancer is the
