Are painkillers also killing your hearing?

When you think of risk factors for hearing loss, over-the-counter painkillers probably aren't among them. But a Harvard study published in a recent issue of the American Journal of Epidemiology suggests frequent use of ibuprofen (Advil, Motrin) or acetaminophen (Tylenol) may be an important contributor.

In the study, women who took the pain relievers at least twice per week were at a greater risk for hearing loss, and more frequent usage increased the risk by up to 24 percent. The findings are similar to a study of men and hearing loss, although aspirin was also found to contribute to risk in that study.

Researchers speculate the pain relievers may be damaging the cochlea, the snail-shaped hearing mechanism in your inner ear.

"Ibuprofen can reduce blood flow to the cochlea, which could result in cellular damage and cell death. Acetaminophen may deplete the antioxidant glutathione, which protects the cochlea from damage," says study author Dr. Sharon Curhan, an instructor in medicine at Harvard Medical School.

Does this mean you should think twice before popping a pill for headache or back pain?

"These drugs clearly have benefits with short-term use," says Curhan. "However, frequent use of these medications and use over long periods of time may increase the risk of hearing loss and may cause other adverse health effects. Therefore, it is important to take these medications mindfully and to limit their use as much as possible."

Talk to your doctor before making any changes in your medication use.

2012 cancer findings

The American Institute for Cancer Research has released the top 8 scientific findings in 2012 that advanced the field of cancer prevention.

• Pancreatic cancer is preventable. A healthy weight can prevent 19 percent of pancreatic cancer cases.

• Exercise helps cancer survivors. Physical activity in cancer patients helps improve function, quality of life, body weight, strength and fatigue.

• Soy is safe, despite previous warnings. Breast cancer patients and survivors can safely eat moderate amounts of soy.

• Inactivity is harmful. Sedentary lifestyle causes 10 percent of both breast cancers and colon cancers.

• Lightening our heavy nation. Two-thirds of adults are overweight or obese, which increases the risk of seven cancers.

• Sugary drinks linked to weight increase. Regular consumption of sugary beverages contributes to weight gain.

• Losing weight for lower risk. Losing weight can reduce chronic inflammation, which is linked to some cancers.

• How to keep weight off. Adding vegetables and fruits is the single most effective strategy for long-term weight loss.
