A comprehensive study, published in The Lancet Public Health, reveals that 6 out of 12 types of cancer are an outcome of obesity or overweight. Furthermore, the research has found that obesity is notably common among the population under 50. Thus, certain cancers mostly show up in younger adults.
The researchers of the study noted a momentous increase in the incidence of multiple myeloma, colorectal, uterine, gallbladder, kidney, and pancreatic cancer among adults. Moreover, they link obesity to cause tumors in the stomach, liver, breasts, ovaries, esophagus, and thyroid.
The author of the study says that this respective research is based upon a review of trends in the incidence of 12 obesity-related cancers. Also, it involves a comparison of these cancer types with 18 other cancers among younger adults. Thus, the team collected and reviewed 20 years of data on those cancers.
The research team studied state registries on patients, ranging in age from 25 to 84, to gather information. 14 million cases, from 1995 through 2014, were diagnosed for the 30 types of cancer.
Dr. Anton Bilchik, a professor of surgery and chief of medicine at the John Wayne Cancer Institute in California, acknowledged the enormous research done to conclude the study. He found the scope of the study very striking.
Bilchik noticed the same trend among his own patients. He operated on four individuals under 55. All of them were diagnosed with advanced-stage cancers that usually affect people in their 60s and 70s.
Two of the patients were obese and the other two had been bulky as children. Pancreatic cancer serves as a good example of the inverse relationship between cancer risk and age.
The authors of the study have found that the probability of pancreatic cancer changed .77 percent per year on average in the 45- to 49-year age group. On contrary, the annual risks of the disease rose by 2.47 percent on average among 30- to 34-year-olds. In the 25- to 29-year-old cohort, the average yearly change was 4.34 percent.
How does obesity connect with cancers?
Experimental study on mice reveals that obesity enhances the uncontrolled growth of cells. Therefore, this possibly results in human malignancies, discovered earlier in life.
According to an estimate, 40 percent of the adults and 18 percent of the young United States’ population is obese. However, their government has set national guidelines for physicians to screen obese individuals.
Dr. George Chang, professor of surgery and chief of colorectal surgery at the University of Texas MD Anderson Cancer Center in Houston, discussed the following probable reasons for the situation,
- Altered metabolism`
- Mutant Genes
- Physician’s inefficiency to calculate the BMI of the patients in routine
- Exposure to environmental factors such as processed foods
People need to understand that their poor lifestyle choices can lead them to lifelong illnesses. They must maintain a healthy and balanced life with healthier food choices and regular exercise.
Thus, the government should make policies to limit the use of processed food and sugary drinks among students and children. There are some communities, taxing sodas and creating pedestrian-friendly areas aiming to enhance physical activity among adults.
Moreover, people not only need to understand the benefits of healthy eating choices and routine exercises but also imply them to their daily life.
