What You Need to Know: Breast Cancer

Do you work at night? It may be healthier to work while the sun is up, because a new study has found a link between night shifts and breast cancer.

A group of researchers from Harvard University conducted an experiment, which was published in Environmental Health Perspectives, to determine how levels of light can impact the disease. 

To do so, they examined 110,000 women and data from nighttime satellite images of each participant’s residential address. They also factored in night shift work.

Scientists found that women exposed to the highest levels of outdoor light at night had an estimated 14 percent increased risk of breast cancer compared to those exposed to lower levels. 

They also saw a stronger link among women who work at night. 

“In our modern industrialized society, artificial lighting is nearly ubiquitous. Our results suggest that this widespread exposure to outdoor lights during nighttime hours could represent a novel risk factor for breast cancer,” lead author Peter James said in a statement.

Why is that?

Light affects melatonin, a hormone that regulates sleep-wake cycles and plays a role in reducing tumor growth. However, exposure to artificial light lowers melatonin levels, preventing it from operating at its full ability. 

Researchers noted that the association between outdoor light at night and breast cancer was only prevalent among premenopausal women and current or past smokers.

They also acknowledged that more research needs to be done to clarify their results and methods.

Petty, who suffered emphysema, knee problems and more recently a fractured hip, was prescribed various pain medications including Fentanyl patches, his family said. 

“On the day he died he was informed his hip had graduated to a full on break and it is our feeling that the pain was simply unbearable and was the cause for his over use of medication,” his family wrote on Facebook

The family called Petty’s Oct. 2 death an unfortunate accident. 

“As a family we recognize this report may spark a further discussion on the opioid crisis and we feel that it is a healthy and necessary discussion and we hope in some way this report can save lives. Many people who overdose begin with a legitimate injury or simply do not understand the potency and deadly nature of these medications.”

Scientists worry brain-wasting 'zombie deer' disease could spread to humans

Deer across North America are dying from a mysterious disease that gradually destroys the animals’ nervous systems.

And scientists are concerned that the infection could make its way to humans. 

Chronic wasting disease — or “zombie deer disease” — was first observed in 1967 in Fort Collins, Colorado, and has since infected wild herds in 24 states and Canada, as well as in South Korea and Norway, NPR reported.

“CWD passes from animal to animal through prions, misfolded proteins that cause other proteins to misfold around them,” NPR reported. “Different prion diseases tend to only harm certain species, but can evolve to overcome those limitations.”

In some herds, as many as half of the animals carry prions.

But direct contact isn’t the only way prions are transmitted. According to The New York Times, sick animals and cadavers can spread prions through plants and soil, which could be coated with deformed proteins for years, perhaps even decades.
An animal infected with the disease can live two years before signs of symptoms -- such as a vacant stare, thick saliva, exposed ribs or drooping heads -- become visible.

There have been no reported human illnesses due to the disease, and scientists don’t have conclusive evidence that infected meat has ever harmed people, suggesting there is a “species barrier” between humans and deer.

Researchers led by Mark Zabel, associate director at Colorado State University’s Prion Research Center, found that macaque monkeys who ate infected deer contracted the disease, the first time the disease was shown to spread to a primate through meat.

"While most research shows there's a robust species barrier, this recent study showed that barrier might not be quite as robust as we once thought," Matt Dunfee, head of the Chronic Wasting Disease Alliancein Fort Collins, Colorado, told NPR.

Zabel and his team also found that the prions involved in the “zombie disease,” which scientists have only known about for 50 years, are probably still evolving, “which leads us to believe it's only a matter of time before a prion emerges that can spread to humans,” NPR reported.

Mad cow disease, for example, is a prion disease that evolved from scrapie, a deadly disease that afflicts sheep. Once the prions were passed to cows, the cows developed a prion disease of their own (mad cow disease). And when humans ate the beef from those sick cows, they developed prions in their own brains. As of 2016, according to the Food and Drug Administration, 231 people had died from the condition.

Zabel believes the only way to get rid of CWD prions is to set controlled fires. But “there’s a lot that we still don’t know and don’t understand about the disease,” Zabel said in an interview with The New York Times.

According to Michael Miller, senior wildlife veterinarian for Colorado Parks and Wildlife, mule deer transmission more than tripled toward the end of 2017, and CWD continues to be prevalent in Colorado.

Public health officials in the area have been monitoring for CWD and human brain-wasting diseases, such as Creutzfeldt-Jakob disease.

But over the past 21 years, rising rates of both diseases haven’t impacted human health.

Still, as a precaution, Dunfee told NPR, "if you are hunting in an area where CWD is found, have your animal tested. If it comes back positive, don't eat the meat."
