The PE-PUR foam in recalled Philips CPAP devices releases over 200 chemical compounds when it degrades — including known and suspected human carcinogens. These chemicals travel directly from the device into your airway, exposing your upper respiratory tract, lungs, and through systemic absorption, your kidneys, liver, and bladder. The type of cancer linked to your exposure depends on where in your body these carcinogens accumulate and cause cellular damage.

Nasopharyngeal cancer is the most common cancer type among MDL 3014 plaintiffs — the nasopharynx receives the most direct foam chemical exposure during device use. Lung cancer (adenocarcinoma and squamous cell) is the second most prevalent. Kidney and liver cancers result from systemic absorption and metabolic processing of carcinogenic VOCs. Bladder cancer has been reported due to TDI metabolites excreted through the urinary tract. Throat, thyroid, and other head and neck cancers round out the recognized cancer types in this litigation.
