Philips CPAP Cancer Risk

Philips CPAP cancer risk is linked to degraded sound abatement foam in recalled Philips CPAP, BiPAP and ventilator machines. Users can ingest or inhale foam particles and gases that may cause cancer and other problems. CPAP machines not included in the recall don’t have an elevated cancer risk.

Does Philips’ CPAP Machine Cause Cancer?

Normally, Philips CPAP machines don’t cause cancer. In fact, people with sleep apnea who use CPAP or BiPAP machines can reduce their risk of cancer and other health problems.

But CPAP, BiPAP and ventilator machines involved in the Philips CPAP recall contain polyester-based polyurethane (PE-PUR) sound abatement foam — used to dampen sound and vibration while devices are operating — that may break down.

According to Philips, particles and gases released by degraded foam could cause cancer and other toxic effects if they enter the body.

Health risks related to inhaling or ingesting foam gases or particles include:
  • Airway inflammation
  • Airway irritation
  • Headache
  • Dizziness
  • Skin, eye, nose and respiratory tract irritation
  • Nausea
  • Vomiting
  • Hypersensitivity
  • Carcinogenic and toxic effects

What Cancers Can a Philips CPAP Machine Cause?

Researchers have yet to study the specific types of cancer caused by the foam in recalled Philips CPAP machines. Exposure to foam particles may increase the risk of organ cancers, such as kidney and liver cancer, according to an FDA Safety Communication.

Most of the Philips CPAP cancer risk comes from chemicals in PE-PUR foam, including isocyanates. Isocyanates are potential human carcinogens that are known to cause cancer in animals, according to the Occupational Safety and Health Administration. These compounds also cause asthma and lung problems, and some studies have found an increased risk of lung cancer. They also affect the eyes, nose, throat and skin. Other cancers associated with polyurethane include non-Hodgkin lymphoma and rectal cancer.

In addition, Philips CPAP lawsuits have named several other cancers as potentially caused by PE-PUR foam.

Cancers linked to PE-PUR foam in studies and CPAP lawsuits include:
  • Bladder Cancer
  • Brain Cancer
  • Breast Cancer
  • Hematopoietic Cancer
  • Kidney Cancer
  • Leukemia
  • Liver Cancer
  • Lung Cancer
  • Lung Damage
  • Lymphatic Cancer
  • Multiple Myeloma
  • Nasal Cancer
  • Non-Hodgkin Lymphoma
  • Papillary Carcinoma
  • Prostate Cancer
  • Rectal Cancer
  • Stomach Cancer
  • Testicular Cancer
  • Thyroid Cancer

Why Is PE-PUR Foam Potentially Dangerous?

Intact PE-PUR foam might be relatively harmless, but if the foam breaks down it can release particles and chemical gases, according to Philips. If these particles or gases enter the body through the nose or mouth they can cause a variety of health issues.

“These issues can result in serious injury, which can be life-threatening, cause permanent impairment, and require medical intervention to prevent permanent damage,” the U.S. Food and Drug Administration said in its Safety Communication.

Even if there are no visible particles, the foam may already be breaking down and releasing harmful chemicals.

Philips’ lab analysis found degraded foam produced several potentially harmful chemicals, including:
Toluene diamine
A chemical used to make polyurethane, dyes, hydraulic fluid and sensitizers for explosives. Health hazards include: Genetic defects, skin reactions, toxicity, cancer, damaged fertility and organ damage.
Toluene diisocyanate
A chemical used to make foams and coatings. Health hazards include: Eye damage, skin irritation, may be fatal if inhaled, respiratory irritation and cancer.
Diethylene glycol
A chemical used to make other chemicals that can irritate skin, eyes and mucous membranes and may be slightly toxic if swallowed.
Dimethyl diazene
A chemical used to make other chemicals.
Phenol, 2,6-bis (1,1-dimethylethyl)-4-(1-methylpropyl)
A chemical used to make other chemicals.

People whose CPAP devices are affected by the recall should speak to their doctors about Philips CPAP alternatives. This may mean stopping CPAP treatment, finding another CPAP machine or exploring alternative treatment options such as lifestyle changes, oral devices or surgery.

Symptoms of Exposure to Philips CPAP Machine Foam Particles

Some Philips CPAP side effects are typical side effects patients can expect from regular CPAP treatment. But exposure to foam particles from Philips’ recalled CPAP machines can cause additional adverse events.

Philips received several reports of potential symptoms of exposure to foam particles or gases. These include: Headache, upper airway irritation, cough, chest pressure and sinus infection.

Other potential side effects include: Skin, eye, and respiratory tract irritation and inflammation; headache; asthma and adverse effects to kidneys, liver and other organs.

Other Potential Health Risks of Inhaling PE-PUR Foam Chemical Emissions

In addition to cancer, inhaling PE-PUR foam chemical emissions may cause airway inflammation and irritation as well as lung and heart problems.

People with reduced cardiopulmonary reserve – problems with the heart and lungs — or underlying lung diseases are especially vulnerable.

Philips’ lab tests found gases released by broken down foam exceed safe exposure thresholds. Potential health risks include: Dizziness, headache, vomiting, nausea and irritation (skin, eyes, nose, and respiratory tract).

CPAP lawsuits list other health problems potentially caused by PE-PUR chemical emissions include:
  • Acute Respiratory Distress System (ARDS)
  • Chemical Poisoning
  • Heart Attack
  • Heart Failure
  • Pleural Effusion
  • Reactive Airway Disease (RAD)
  • Respiratory Failure
  • Severe Ear Inflammation
  • Severe Nose Inflammation
  • Severe Throat Inflammation
  • Skin irritation

What to Do If You’ve Been Diagnosed with Cancer

If you’ve been diagnosed with cancer after using a Philips CPAP machine, you should find a qualified oncologist who can help develop a treatment plan for your specific type of cancer as soon as possible.

Tell your doctor that you’ve used a recalled Philips CPAP machine. Your doctor may be able to connect the cancer to your CPAP device. Your cancer may be connected to toxic PE-PUR foam in a Philips CPAP, and you could be eligible for compensation.

Compensation from a Philips CPAP lawsuit could help you pay for your cancer treatment as well as any future care you may need. You may also recover other damages, including: Lost wages, pain and suffering and loss of quality of life.

Make sure you contact an attorney right away if you want to file a lawsuit. There is a time limit to file.

Please seek the advice of a medical professional before making health care decisions.
