People who are overweight or obese are 150% more likely to develop pancreatic cancer at some point in their lives than people with normal weight. However, obesity is not considered a cause of cancer, but simply a risk factor. Smoking, on the other hand, has long been blamed on a quarter of pancreatic cancer cases.
During the tests, scientists analyzed data 963317 people. During the observation period, 8354 people died of pancreatic cancer. The data obtained showed that people under the age of 50 years who were overweight at the beginning of life were more likely to be fatal, even if they were not overweight. For example, a person who was overweight and overweight at age 5-7 was 25% more likely to die from pancreatic cancer between the ages of 30 and 49 than a person who had a healthy weight at that age. If the same person was slim to 50 years old, but at the age of 50 to 59 years old gained extra pounds, the risk of death from pancreatic cancer increased by 19%, while those who were overweight at the age of 60 to 69 years old had a risk increased by 14%. Thus, the earlier a person gained extra pounds, the greater the chances of dying from a difficult to treat disease.
Experts remind that overweight is a major risk factor for many types of diseases, including cancers such as uterus cancer, esophageal cancer, stomach cancer, kidney cancer, liver cancer, some brain tumors, pancreatic cancer, colorectal cancer and multiple myeloma. Studies also show that overweight can make these types of cancer more deadly, and, even if patients survive, they are likely to have a poor quality of life in the future.
