Hospital checks own staff and finds unexplained neuroendocrine lung tumors
Chengching Hospital in Taiwan screened 116 of its administrative managers and head doctors for lung cancer, 13 of them showed abnormalities, and 3 were found to have unexplained neuroendocrine lung tumors of from 0.2 cm to 0.8 cm in size. The affections remain unexplained since they do not smoke.
Radiologist Lee Tsung-hsien strongly suspects that the tumors are the result of PM2.5 pollution. The cancer cells in the three staff members have all penetrated the alveoli. In general, nodules 0.2 cm to 0.8 cm are difficult to detect by X ray. It is suspected that PM2.5 particulates affected the epithelial cells, causing them to grow along the alveoli walls, forming “frosted glass” like nodules.
