The FDA is warning that over-the-counter antacids with aspirin in them can cause stomach bleeding in rare cases. 

Research has found that people with high levels of the oral bacteria Porphyromonas gingivalis had a 59% greater risk of developing pancreatic cancer. It is too early to say whether this specific bacterium directly contributes to the disease. However, one theory is that since inflammation is related to cancer, the bacteria could cause inflammation in the pancreas. Another possibility is the bacteria are simply a marker for cancer-causing inflammation. 

While e-cigarettes do not produce the tar or toxic gases found in cigarette smoke, this doesn’t make them a healthy option. The e-liquid found in e-cigarettes still contains highly addictive nicotine that also increases your risk of insulin resistance and type 2 diabetes. Nicotine also increases the risk of addiction to other drugs and may impair brain development. Rather than rely on the perceived benefits of e-cigarettes, people should avoid smoking altogether.

In April, the U.S. Food and Drug Administration (FDA) approved a new screening test for colon cancer, making it the first blood-based test for this type of cancer. While this test does make it more convenient for people to get screened for colon cancer, it is also less exact than the current screening methods. It is important to discuss your risk factors and screening options with your doctor.

They affect more women, but men still are at risk.

Most people never think about gallstones—that is until they experience the severe, gut-piercing pain of a gallstone attack. "These often strike after eating, especially a high-fat or high-cholesterol meal, and can last about 30 minutes to two or more hours," says Dr. William Brugge, past director of gastrointestinal endoscopy at Harvard-affiliated Massachusetts General Hospital.

The attacks often begin in the upper-right side of the abdomen and may spread to the back, between the shoulder blades, and under the right shoulder. Nausea or vomiting may also occur.

It appears people with the highest levels of physical activity have lower rates of cancer of the esophagus, lung, kidney, colon, head and neck, rectum, bladder and breast, compared with people with the lowest levels of physical activity.

A group of scientists wants to develop technology to create a synthetic human genome, which could lead to improved organ transplantation, vaccines and medicines, and to new ways to fight cancer and infections.

It appears that four healthy habits—getting 150 minutes of moderate-intensity exercise per week, maintaining a body mass index between 18.5 and 27.5, no smoking, and drinking only in moderation—may prevent many cancer cases and death in white people.

Letters notifying women that they have dense breasts are difficult to understand. Women receiving them should contact their doctors.

A Harvard study published March 3, 2016, in JAMA Oncology adds to increasing evidence that aspirin use may help stave off colorectal cancer and suggests that aspirin is also associated with a small reduction of overall cancer risk.

Researchers looked at aspirin use among almost 136,000 men and women in two studies over 32 years. They noted that regular aspirin use—taking either a 325-mg tablet or an 81-mg tablet two or more times per week—was associated with a 3% reduction in cancers over all, although they saw no effect on major cancers like those of the breast, prostate, or lung. The researchers say the overall reduction was due mostly to a 15% risk reduction for gastrointestinal cancer and a 19% risk reduction for colorectal cancer.
