Obesity linked to 10 common cancers
Obesity or simply being overweight can put people at risk of developing 10 of the more common cancers, according to researchers from the London School of Hygiene and Tropical Medicine.
The scientists gathered data on 5 million people living in the U.K. and monitored changes to their health over a period of seven years. They found that each 13-16 kg of extra weight an average adult gained was linked directly to a greater risk of developing six cancers, including cancers of the uterus (the highest increased risk), gallbladder, kidney, cervix, thyroid and leukemia. People with a high body mass index were also at a higher risk of developing liver, colon and ovarian cancer.
Body Mass Index (BMI) seemed to affect cancers differently, however. For instance, the researchers noted that risk of uterine cancer increased substantially at a higher body mass index, but showed no increased risk for other cancers. In fact, it noted that a higher BMI is associated with a lower chance of developing prostate cancer. While it’s unclear how obesity may feed tumor growth, researchers say the link between the two is clear.

Almost half of Americans will develop diabetes
The incidence of type 2 diabetes is rapidly rising in the U.S. and new research now suggests that 40 percent of Americans will develop type 2 diabetes in their lifetime.
For the study, researchers analyzed data from the National Health Interview Survey, which disclosed diabetes incidence in the U.S. from 1985 to 2011. They also assessed the death certificates of 598,216 adults.
They found that for an average 20-year-old American, the lifetime risk of developing type 2 diabetes increased from 20 percent in the period from 1985 to 1989 to 40 percent in the period from 2000 to 2011 for men. The lifetime risk for women increased from 27 percent to 39 percent. Hispanic men and women and non-Hispanic black women saw the highest increase at 50 percent.
The years of life lost due to diabetes decreased, however, from 7.7 years to 5.8 in men diagnosed with diabetes at age 40 and from 8.7 to 6.8 for women.
Experts say as the number of diabetes cases continues to grow, and patients live longer, there will be a greater demand for health services and extensive costs. This makes lifestyle changes increasingly important to help rein in fast-rising healthcare costs.
