Here’s why lung-cancer patients should move to areas with better air quality

Scientists have long known that people living with air pollution have a greater chance of developing lung cancer. But what does dirty air do to those already diagnosed with the disease?

University of Southern California researchers now believe it can shorten their lives by several years, according to a study released Thursday.

A research team at USC’s Keck School of Medicine found that California patients with early-stage lung cancer who live where the air is clean can survive twice as long as patients breathing polluted air.

Those living with good air quality survive almost six years.

So tailpipe emissions, smoke and other fine-particle pollution appears to continue harming people after the disease begins, said Sandrah Eckel, an assistant professor of preventive medicine at USC.

It appears to “promote the progression of their disease through the same biological pathways” that caused the disease in the first place, Eckel said.

Other research has found that microscopic pollution damages cells, turning on genes that start the formation of cancer.

The USC team cautioned that more research is needed to learn exactly how pollution affects ongoing cancer.

The shorter cancer survival times were found in areas with higher levels of microscopic fine particle pollution. This kind of pollution is an airborne stew of diesel soot, wood smoke, dust and chemical compounds that form when various pollutants react with each other.

The good news is that the research team didn’t observe a similar correlation with ozone pollution – the bane of Southern California’s summer smog season.

Still, the area last year failed to meet the federal deadline to bring fine particle pollution levels down to healthful levels, with 35 days exceeding a federal health standard.

The worst problem is in the Mira Loma area of Jurupa Valley in northwest Riverside County, said Philip Fine, deputy executive officer for the South Coast Air Quality Management District.

Since the 1990s, Mira Loma has developed into a busy warehousing district at the crossroads of Interstate 15 and the 60 Freeway used by thousands of diesel trucks every day. Unhealthful particle pollution also persists in California’s Central Valley.

Eckel and her colleagues looked at more than 350,000 cancer cases reported to the California Cancer Registry between 1988 and 2009. The team assigned average pollution exposure at each patient’s home using air pollution data tracked by the U.S. Environmental Protection Agency.

The median survival time for those living with higher levels of fine particulate pollution was 2.4 years as compared with 5.7 years in patients living in areas with low levels of the pollution.

Eckel said cancer patients may want to consider air quality along with their treatment options.

“They may want to install air filters in their homes,” she said. Asked if patients living more polluted areas should move, she replied: “If they have the resources.”

• The Surgeon General has determined that there is no safe level of exposure to ambient smoke!

• If you smell even a subtle odor of smoke, you are being exposed to poisonous and carcinogenic chemical compounds!

• Even a brief exposure to smoke raises blood pressure, (no matter what your state of health) and can cause blood clotting, stroke, or heart attack in vulnerable people. Even children experience elevated blood pressure when exposed to smoke!

• Since smoke drastically weakens the lungs' immune system, avoiding smoke is one of the best ways to prevent colds, flu, bronchitis, or risk of an even more serious respiratory illness, such as pneumonia or tuberculosis! Does your child have the flu? Chances are they have been exposed to ambient smoke!
