EPA bans 2 cancer-causing chemicals used in everyday products — like dry-cleaning agents

While still under the aegis of Joe Biden,  the EPA banned two cancer-causing chemicals used in everyday products; now, many observers believe, it's only a matter of time until Donald Trump tries to revoke that decision.

The chemicals — perc, an industrial solvent used commonly in dry cleaning, and TCE, a substance found in consumer and manufacturing products (including de-greasing agents) — are known carcinogens, according to a recent story by Amudalat Ajasa in The Washington Post.

For instance, TCE, formally known as trichloroethylene, is associated with non-Hodgkin's lymphoma, leukemia, and kidney and liver cancers. The substance also is found in furniture care and auto repair products.

Perc, also known as PCE and perchloroethylene, is a solvent long used in applications of auto repair as well as in dry cleaning.

The two chemicals apparently have been seeping into the environment through the soil and waterways.

The Post article quotes Michal Freedhoff, the Environmental Protection Agency's assistant administrator for the Office of Chemical Safe and Pollution Protection and a PhD, to the effect that "the bans will protect workers, consumers, and residents from the chemical's harms."

Jonathan Kalmuss-Katz, a senior attorney at Earth Justice is also quoted: "Both of these chemicals have caused too much harm for too long, despite the existence of safer alternatives."

Medical risks expanding along with waistlines

Cancer dangers from obesity are growing exponentially, article in The Washington Post indicates


Obesity may overtake smoking as the No. 1 preventable cause of cancer.

According to a story by Laurie McKinley in The Washington Post a while back, the change is due to waistlines continuing "to expand while tobacco use plummets."

McKinley notes that Dr. Otis Brawley, ex-American Cancer Society (ACS) chief medical officer who's now a Johns Hopkins oncologist, says the switch may take five to 10 years.

What's happening, she quotes Dr. Jennifer Ligibel, a breast oncologist at the Dana-Farber Cancer Institute, as saying, is that "a complex interplay of metabolism, inflammation and immunity…creates an environment that is more permissive for cancer."

The Post also quotes Dr. Jonathan Wright, a urologist at Fred Hutchinson Cancer Research, to the effect that "it does appear that the risk is greater the more obese you are."

Only about half the American public purportedly is aware of the link between excess weight and cancer. 

The deadly combo has long been known to increase the risk of heart disease and diabetes — and now is being associated, according to the Post, "with an increased risk of getting at least 13 types of cancer, including stomach, pancreatic, colorectal and liver malignancies, as well as postmenopausal breast cancer."

ACS researchers contend that "excess body weight is linked to about 8 percent of all cancers in the United States and about 7 percent of cancer deaths," McKinley reports.

She also writes that "compared with people of normal weight, obese patients are more likely to see their cancer come back and have a lower likelihood of survival. Perhaps more alarming, young people, who as a group are heavier than their parents, are developing weight-related malignancies, including colorectal cancer, at earlier ages than previous generations, experts say."

An article in JAMA Internal Medicine (the journal of the American Medical Association) several years ago maintained that "seven in 10 Americans are overweight or obese." But the obesity rate has been rising exponentially since that piece was published.

The type of cancer most associated with obesity, McKinley writes, "is endometrial, which develops in the lining of the uterus. Obese and overweight women are two to four times as likely to develop the disease as women of normal weight, and the risk rises with increased weight gain, according to the National Institutes of Health."

Statistics from that source also indicate that "people who are overweight or obese are twice as likely to develop liver and kidney cancer, and about 1.5 times as likely to develop pancreatic cancer than normal-weight people, according to NIH."

Several researchers, McKinley says, "are running clinical trials to prove what many already believe — that losing weight reduces the odds of developing cancer or having a recurrence." 

If studies show that to be true, she adds, "doctors could prescribe a weight-loss program as standard therapy for breast cancer patients — much as cardiac rehabilitation is urged for heart-attack patients. That could pave the way for insurance coverage."

New insights, treatments, tests in disease 'war'

Medical community is starting to believe less is more when it comes to cancer treatments 


More and more doctors and patients apparently are using less aggressive weapons to fight cancer these days.

Dr. Justin Bekelman
A story by Laurie McKinley in yesterday's Washington Post quotes Dr. Justin Bekelman, a radiation oncologist at the University of Pennsylvania, about the medical community's focus on the "war on cancer."

Historically, he says, that phrase "implied that more is better and decimation is desired."


McKinley's story contends, however, that the idea is "falling out of favor," not only because it "subtly blames patients" who die "but also because it doesn't capture a world of new biological insights, improved treatments and molecular tests that are transforming how cancer is treated."


According to Bekelman, "Knowing when not to treat" can be "great medicine" — because, the story charges, oncologists equipped with new tools and evidence can cut back on toxic and costly approaches likely do more harm than good.

Cancer, nevertheless, is not monolithic, the story indicates.

Rather, some cancers "need to be bludgeoned, but others can be treated with more tailored therapies or simply watched."

Although the latest mindset of "doing less in the face of danger" can be "emotionally difficult" for both patients and physicians, the article notes, proof that less is more has been frequently popping up lately, including a landmark clinical trial published in June that found more than "two-thirds of women with early-stage breast cancer can safely avoid chemotherapy." 

Not to mention the fact, according to the piece, that "men with early-stage, low-risk prostate cancer are rapidly embracing 'active surveillance' over surgery — and avoiding possible complications such as incontinence and sexual dysfunction," and that throat cancer caused by human papilloma virus, because it varies from other types of the disease, allows a cutback "in a brutal treatment regimen and [reduces] the risk of potentially devastating disfigurement."


The Post story also mentions the emergence of immunotherapy, usually less toxic than chemo, "as a first-line treatment for many patients," and cites a recent study showing that "people with advanced kidney cancer can skip surgery to have their kidneys removed and instead go right to drug treatment."


De-escalation isn't happening universally, however. 


McKinley contends that the "most common form of thyroid cancer, which poses little risk, is often still treated with unnecessary surgery, experts say. And some malignancies, such as pancreatic cancer, are so lethal that doctors are racing to find ways to ramp up treatment."
