Cancer from obesity: Constant weight gain in adults significantly increases the risk of cancer

Obesity and obesity greatly increase the likelihood of cancer
In old age, many people eventually develop weight problems. Researchers have now found that weight gain in adults increases the risk of cancer. For this reason, with increasing age it is particularly important that adults pay attention to a healthy body weight.

Scientists from the University of Manchester and the Health eResearch Center found in an investigation that weight gain in adults increases the risk of cancer. The doctors published the results of their study at the National Cancer Research Institute’s (NCRI) Cancer Conference in Liverpool.

Obesity increases the risk of cancer by 50 percent in men
A significant weight gain over the years often leads to obesity. This has a significant impact on the risk of developing cancer. In men with a sharp rise in the BMI, the risk of cancer increases by more than 50 percent, in women in this group the cancer probability increased by almost 20 percent, the scientists explain.

Large study examines 300,000 adult Americans
The current study leads to a new look at the long-term effects of obesity and its connection to the development of cancer, the authors explain. For their study, the scientists examined the data from almost 300,000 people in America. These included 177,500 men and 111,500 women. The doctors looked at the changes in the BMI between the ages of 18 and 65.

Subjects were medically monitored over a period of 15 years
Some of the participants gained some weight, other subjects became morbidly obese. The researchers divided the test subjects into different groups depending on the increase in BMI and observed them over an average of 15 years. This is how it should be determined whether the affected people develop cancer over time, the scientists explain.

A BMI that is too high has a massive impact on cancer risk
Men with a BMI with a sharp rise in BMI had a drastically increased risk of developing cancer compared to men with normal weight. When men became pathologically obese from weight gain, the risk of cancer increased by 53 percent, the doctors say.

Many subjects with a high BMI had cancer after the age of 65
The women 's sharp rise in BMI had a 17 percent increased risk of cancer compared to women with healthy body weight, the authors explain. Of the 300,000 people in the study, approximately 9,400 women and 5,500 men aged 65 and over were diagnosed with cancer related to obesity, the researchers report.

Results provide better understanding of how cancer develops
Current research shows how important it is to monitor a person's weight gain over the course of a lifetime. This makes it possible to create a clear picture of the cancer risk in connection with the BMI, explains Dr. Hannah Lennon from the University of Manchester.

Study could help identify people with increased cancer risk faster
This study could be really useful for public health. It could help identify people with an increased risk of cancer, the authors say. This way, those affected can control their weight before any health problems arise.

Better understanding of the harmful effects of weight gain
The new research is an interesting way to look at the cancer risk that obesity creates in life, the scientists explain. As a result, the harmful effects of weight gain over longer periods of time can be better understood, the experts continued.

Small changes in diet lead to healthy body weight in the long run
It is important to inform people about their options for reducing their risk of developing cancer, the researchers explain. Of course, there are no guarantees that cancer will occur in humans. Nevertheless, a healthy body weight can reduce the likelihood of the disease and also bring many other health benefits, the doctors say. Even small changes in diet can contribute to a healthy body weight in the long run.

Results enable a better assessment of the cancer risk
This study provides a deeper understanding of the health effects of the obesity epidemic. The results show that overweight can significantly increase the risk of cancer over time. However, this finding could also make it possible to better assess the risk of an individual suffering from cancer. (as)
