Obesity affects a number of mechanisms inside the body that can lead to an increased risk of several types of cancer, researchers say.
For years, medical professionals have stressed the importance of maintaining a healthy body mass index (BMI).
While some contend there are more important numbers to focus on, research tells us that a higher than normal BMI could be linked to all sorts of health conditions.
Now, it turns out those conditions might include some types of cancer.
A study in Cancer Letters found that the growth and spread of multiple myeloma increases as a person’s BMI rises.
About 10 percent of all blood cancers are multiple myeloma. Doctors typically detect it with blood tests, though biopsies can be used as well.
In 2015, researchers in Sweden published a report in Cancer Cell about a blood test they developed that accurately detected cancer 96 percent of the time. It also specified the type of cancer detected with 71 percent accuracy.
"Once a person with cancer is out of the normal weight category, their BMI is contributing to multiple myeloma growth and progression," said Katie DeCicco-Skinner, associate professor of biology at American University and lead study author.
While BMI can’t help doctors detect the cancer — laboratory tests do — the finding could help doctors better treat overweight and obese cancer patients.
“Fat cells from overweight, obese, or morbidly obese individuals all enhanced factors linked to cancer progression more than fat cells from normal weight individuals,” DeCicco-Skinner told Healthline. “Even a BMI in the overweight category could accelerate cancer progression.”
She said that numerous epidemiological studies have shown that obese people are more likely to develop multiple myeloma as well as have significantly shorter overall survival.
“BMI is a risk factor for multiple myeloma,” she stated.
