New research suggests that up to 40% of all cancers are linked to obesity and reveals that the illness could be avoided if weight was controlled. Vital Signs is a report conducted in collaboration by researchers at the National Cancer Institute and the Centers for Disease Control and Prevention (CDC).
The definition of ‘overweight’ is when an individual has a body mass index (BMI) of 29.9 to 25 kilograms each square meter; an individual hits obesity with a BMI of 30 or more kilograms/square meter.
Researchers of the report looked at cancer rates via numbers from the 2014 United States Cancer Statistics and also reviewed trends from 2005 to that year. They looked closely at 13 types of the illness that have been linked in the past to being obese or overweight. The research team analyzed and grouped numbers by geographic region, sex, ethnicity, and age, as well as the area where a participant’s cancer showed up.
Upon their review they discovered that in 2014, about 630,000 in the U.S. were diagnosed with one of these 13 types of cancer they looked at, representing 40% of cancer diagnosed cases. The rate was quite high when it came to those aged 50 or older, where two out of three of these types of cancers were discovered in those between the ages of 50 to 75.
Interestingly enough, Medical News Today revealed that cancer cases were connected more to obese females versus men. In fact, 55% of the cancer cases were linked to obese women, while 24% were linked to obese men.
Director of the CDC, Dr. Brenda Fitzgerald, chimed in on the report stating that a large portion of adults in the U.S. weigh more than what is recommended; being obese or overweight places individuals at an increased risk when it comes to some cancers. She added that the results reveal a cause for concern to ensure individuals are at a healthy weight, which could help with cancer prevention.
