[Scientists discover new human organs may help reduce the side effects of cancer treatment] Recently, scientists have discovered that a new organ in the throat may help reduce the side effects of certain cancer treatments. Researchers from the Netherlands Cancer Institute (NCI) said they discovered new salivary glands in the upper part of the throat behind the nose during a study. Experts previously believed that there are only three salivary glands in humans, located below the tongue, below the mandible, and behind the cheek behind the mandible. Until now, they believed that there were only tiny salivary glands in the nasopharyngeal area behind the nose. However, the researchers said that this newly discovered salivary gland organ may be used to moisturize and lubricate the upper throat. The researchers named this "tubular gland". The results of the study were published in the October 16th issue of "Radiation Therapy and Oncology".
