For a long time, bowel cancer was considered a disease that mainly affected older people. However, in recent years this perception has changed as this type of cancer has been spreading more rapidly among young individuals.
This shift has raised concern among medical experts worldwide, as an increasing number of cases are being reported in people under the age of 50.
A new study published in the journal The Lancet Oncology has now identified the factors behind the rising spread of this cancer among younger people.
According to the study, between 2013 and 2017, cases of this type of cancer increased among people under the age of 50 in 27 out of 50 countries. The highest number of cases were reported in North America and Europe, but a significant rise was also observed in Eastern Europe, South, Central and Southeast Asia, and South America.
Researchers believe that global changes in daily lifestyles are responsible for this trend. For example, dietary patterns have changed, physical activity has decreased, while urban living and environmental issues are also important contributing factors.
The study identified diet as the biggest factor increasing the risk of bowel cancer. High consumption of ultra processed foods, red and processed meat, and sugary drinks increases inflammation in the body and raises the risk of cancer.
In this regard, a study conducted in Kazakhstan found that meat consumption had increased by nearly two times, and this dietary imbalance increased the risk of cancer. The research also identified obesity as another major factor increasing the risk of this type of cancer.
Excess body fat triggers chronic inflammation and affects metabolic functions. According to researchers, the role of obesity may be more complex, as one analysis revealed that most people diagnosed with bowel cancer experience weight loss before diagnosis.
They also noted that genetics play an important role. They further stated that despite the importance of early detection, the symptoms of this type of cancer are often ignored.
Common symptoms include changes in bowel habits, blood in stool, unexplained weight loss, and abdominal discomfort.
