Scientists continue to explore the health benefits versus risks of aspirin therapy. One new analysis suggests that taking aspirin may protect against several types of digestive tract cancers. The results were published online April 1, 2020, by Annals of Oncology.

Researchers examined 113 observational studies of cancer in the general population. They found that individuals who took aspirin regularly — at least one or two tablets a week — had significantly lower rates of cancers of the bowel, stomach, gallbladder, esophagus, pancreas, and liver, compared with people who did not take aspirin.

A new tool to identify people who might be at higher risk for pancreatic cancer could help doctors find cases earlier, when they are most treatable. Researchers from the Harvard T.H. Chan School of Public Health created a risk model that did a better job than current models of finding people at high risk for the disease. It takes into account clinical and genetic factors as well as blood levels of biomarkers (substances that could potentially indicate disease). To test the model researchers used data from four large clinical studies. They applied the tool to 500 known pancreatic cancer patients and more than 1,000 people without cancer. The researchers then assessed how well the tool would have predicted the risk of pancreatic cancer. Pancreatic cancer, which is the third leading cause of cancer death in the United States, is challenging to treat because most people already have advanced disease when they are diagnosed. It's hoped that identifying people who are at high risk will eventually allow doctors to screen these individuals to find cancers when they are smaller and more curable.

Most people understand the risks of sun exposure, even if they do not regularly wear sunscreen, but getting younger people to pay attention to this concern can be difficult. A study chose a novel approach to this problem by appealing to teenagers’ vanity and focus on their appearance.

Tinted sunscreens offer all the benefits of traditional sun protection products, plus they have added pigments that give them the ability to block visible light, which can also be harmful to the skin.

According to a report published March 12 in the journal Cancer, the rate of death from cancer has continued to decline in the United States, dropping on average 1.5% a year from 2001 to 2017. The decline showed up for all ethnic and age groups between 2013 and 2017. The findings were based on cancer incidence data collected by the CDC and the National Cancer Institute.

But not all news was good: the number of new cancer diagnoses in women rose slightly during 2012 to 2016. A more detailed look at cancer deaths among women found a drop in cancer deaths for a majority of the most common cancers, including breast cancer, melanoma, lung cancer, and colorectal cancer. But deaths in women increased when it came to uterine, brain, liver, heart, and pancreatic cancer.

Certain foods may trigger inflammation in the body that can increase a person's risk for colon cancer, suggests a study published online Jan. 18, 2018, by JAMA Oncology.

Researchers followed the diets of more than 121,000 people (46,800 of whom were men) for 26 years. Participants recorded what they ate, and their diets were scored based on the amount of foods consumed that are linked to inflammation, such as red and processed meats, sugary beverages, and refined grains.

Good news on health –– which seems hard to come by right now –– includes declines in the rates of six out of 10 major causes of death in the United States.

A study of older adults found that those who had had more sexual partners were more likely to have developed cancer, but that does not mean there is a causal connection, and there are many ways that sexual behavior can affect cancer risk.
