The ability of ethylene oxide to damage DNA makes it an effective sterilizing agent but also accounts for its cancer-causing activity.
Lymphoma and leukemia are the cancers most frequently reported to be associated with occupational exposure to ethylene oxide.
Stomach and breast cancers may also be associated with ethylene oxide exposure.
The primary routes of human exposure to ethylene oxide are inhalation and ingestion, which may occur through occupational, consumer, or environmental exposure.
E. Appearance and odor: Colorless liquid below 10.7 °C (51.3 °F) or colorless gas with ether-like odor detected at approximately 700 parts EtO per million parts of air (700 ppm).

Well at least its not the wind turbines getting the blame this time.
Apparently Ethylene Oxide its used primarily to produce other chemicals, like antifreeze, in smaller amounts, as a pesticide and also sterilizing agent.
So it hardly just PPE masks that risk exposure to Ethylene Oxide considering the multitude of uses it has as a sterilizing agent.

Ths sterilization process seems very much like dry cleaning, applying a liquid that evaporates into a gas leaving no trace.

Well, then you're probably not going to like the chemicals in the air around your car when you are sitting in traffic. Might as well get rid of cars. And it's probably not a good idea to take kids anywhere.

I wonder how many surgeons have contracted cancer from the masks they wear?

Ever take a whiff of your suit after you pick it up from the dry cleaner?

Apparently, many sterilized masks being sold (about 50%) DO contain a known carcinogen called Ethylene Oxide.
Ethylene Oxide is recognized by the FDA and the National Cancer Institute as a deadly carcinogen...and it is used as part of the sterilization process in face mask production.
Prolonged exposure to Ethylene Oxide is not advised by the FDA...and wearing sterilized face masks for prolonged periods of time...would certainly seem to constitute 'prolonged exposure'.

So...caution is definitely advised when wearing masks for any prolonged length of time.
Take care when selecting a mask to wear...as it may be sterilized using an ethylene oxide process.
(Note: Ethylene Oxide also goes by the name 'Oxirane'.)
Again...please check to see if any mask you are given or are choosing to wear has been sterilized using either Ethylene Oxide or Oxirane.

However its not antifreeze or pesticides in this instance.
But a sterilisation agent, in this case used to clean the masks, that dissipates as a gas above 11°C.
That's all you need to know right there.
You relies that you soak up more carcinogens simply sitting in traffic right?
The Centers for Disease Control & Prevention (CDC) states that “Ethylene oxide is not recommended as a crisis strategy [for cleaning filtering face piece respirators] as it may be harmful to the wearer.”
