This investigative report looks at several medical abnormalities affecting "chip-makers" and "drive-makers" working in IBM "clean rooms." In IBM labs across the country, workers were unknowingly being exposed to carcinogens such as KTI 820, Methylene Chloride, and glycol ethers. As a result many workers later discovered that they had a range of different types of cancer- breast cancer, brain cancer, and testicular cancer. In one case of one 10-person work group, eight people were diagnosed with cancer- six died. The workers were unaware that the chemicals they were using were known to cause different types of cancer and even birth defects. One woman was specifically told that she could work in the "clean room" while pregnant. Her child was born with rare disease called Retinoblastoma, which is a rare eye cancer found in only 1 of 15,000 children. IBM refused to comment on the situation, and responded to one worker's complaint, "regrettably, cancer is one of the most common causes of death in American adults."
