The report, titled Vital Signs, was compiled by researchers from the Centers for Disease Control and Prevention (CDC) in collaboration with researchers from the National Cancer Institute.
The findings are particularly important given the alarming statistics on obesity in the United States. Between 2013 and 2014, the CDC note, as many as 2 in 3 adults were deemed overweight or obese.
Being overweight is defined as having a body mass index (BMI) between 25 and 29.9 kilograms per square meter, and obesity is defined as having a BMI of 30 kilograms per square meter and over.
Studying obesity and cancer diagnoses
The researchers looked at the 13 types of cancer that have traditionally been associated with being overweight and having obesity. These include a type of esophageal cancer, postmenopausal breast cancer, colorectal cancer, endometrial cancer, gallbladder cancer, and gastric cardia cancer.
The researchers looked at cancer of the kidney, liver, and thyroid, as well as ovarian and pancreatic cancer. The researchers also examined meningioma, which is a slow-progressing type of brain tumor, and multiple myeloma.
Around 630,000 obesity-related cancers
Overall, in 2014, approximately 630,000 people in the U.S. received a diagnosis of one of the cancers mentioned above, which represents a staggering 40% of all diagnosed cancers.
The incidence rate was particularly high among adults aged 50 and above. In fact, 2 in 3 of these cancers occurred in those aged between 50 and 74.
Gender-wise, more cancers were linked with obesity in women than in men. And more specifically, 55% of the cancers affecting women and 24% of those affecting men were related to obesity.
Regarding obesity-associated cancers, these rose by 7% between 2005 and 2014. By comparison, the incidence of cancers not associated with obesity declined by 13% during that time.
