They described surgery as the most effective treatment for weight loss
Doctors warn: Obesity is a gateway to 13 types of cancer
A study conducted by the global health care system “Cleveland Clinic” found that weight loss resulting from bariatric surgery in adults was associated with a 32% lower risk of cancer and a 48% lower risk of death from cancer compared to adults who did not undergo this type of surgery. .
The results of this research study were published in the journal JAMA Medical Network.
In 2016, the World Health Organization estimated that more than 650 million adults aged 18 or older worldwide were obese.
In the United States, the Centers for Disease Control and Prevention said obesity increases the risk of 13 types of cancer, representing 40% of all cancers diagnosed annually in that country.
Bariatric surgery is currently the “most effective treatment for obesity,” said Dr. Ali Aminian, director of the Obesity and Metabolic Institute at Cleveland Clinic and lead author of the study’s research report. He noted that patients can lose between 20 and 40% of their weight after surgery. Weight loss can last for decades.
The results of this study indicate that the greater the weight loss, the lower the risk of developing cancer.
Described as an investigation of surgical procedures and long-term efficacy in tumors and death, the Cleveland Clinic study is an identical cohort study of more than 30,000 Cleveland Clinic patients.
A group of 5053 adult patients who underwent bariatric surgery between 2004 and 2017, was matched with a control group of 25,265 patients who did not undergo bariatric surgery, with a ratio of one to five.
The study found that after 10 years, 2.9 percent of patients in the surgical group developed an obesity-related cancer, compared to 4.9 percent of patients in the non-surgical group.
The International Agency for Research on Cancer says 13 types of cancer are linked to obesity, such as endometrial cancer, breast cancer, colon and liver cancer.
After 10 years, 0.8% of patients in the surgery group and 1.4% of patients in the nonsurgical group died of cancer.
The results indicate that bariatric surgery is associated with a 48 percent lower risk of dying from cancer.
The researchers note that the benefits of bariatric surgery were seen in a wide range of study participants, including women and men, young and old.
For his part, said Dr. Stephen Nissen, chief academic officer of the Heart, Vascular and Thoracic Institute and lead author of the study, that obesity is second only to tobacco on the list of preventable causes of cancer.
He believes that the study provides the best evidence of the value of intentional weight loss in order to reduce the risks of cancer and death from it.
More studies
Cleveland Clinic Chief of Hematology and Medical Oncology, Dr. Jim Abraham, stresses the importance of considering bariatric surgery and other treatments that can help prevent cancer and reduce mortality, based on the magnitude of the benefits shown in the Cleveland Clinic study, but he stressed the need to conduct More studies.
