Scientists have discovered a new organ: "a set of salivary glands set deep in the upper part of the throat," LiveScience reports. It had long been believed that the region behind the nose had not contained much more than some "microscopic, diffuse, salivary glands," but it turns out glands about 1.5 inches long, on average, reside there. Prostate cancer researchers at the Netherlands Cancer Institute accidentally made this discovery while using a combination of CT scans and positron emission tomography (PET) scans. This discovery could help cancer patients who require radiation around the head or neck; the examination of over 700 cancer patients treated at the University Medical Center Groningen found that patients who had received radiation in the area of these glands reported more side effects from their treatment. So "the new discovery could thus translate to fewer side effects for cancer patients."
