New Delhi: A new study has linked prolonged viewing time, such as watching television, with increased risk of bowel cancer. Research conducted by Dr. Long Nguyen at Mbadachusetts General Hospital and Harvard Medical School showed that sitting in front of the television for two hours a day or more increased the risk of bowel cancer by up to 70%. .
The study, published in the journal JNCI Cancer Spectrum, is the first to identify the sedentary lifestyle as a factor contributing to the sharp increase in cases of bowel cancer, sometimes called colorectal cancer, in people under 50 years of age.
What is the cancer of the intestine and what are the symptoms?
Cancer of the intestine is a general term that refers to cancer that begins in the large intestine (colon) and in the pbadage of the back (rectum). It is treatable, but the earlier the disease is detected, the easier it is to treat.
Signs and symptoms of bowel cancer may include:
- Bleeding of your bad
- Blood in your stool
- Persistent and unexplained change in intestinal habits – lasting for at least 3 weeks
- Unexplained weight loss
- Extreme fatigue without obvious reason
- Pain or size in the abdomen
You should consult a doctor if you have one or more of the symptoms of bowel cancer, especially if they persist for more than four weeks. Read – 13 Types of Cancer Related to Obesity or Overweight: Tips to Prevent Belly Fat and Reduce the Risk of Cancer
Risk of bowel cancer and television viewing: what do the research say?
The researchers studied sedentary behaviors, including the length of television viewing, of 89,278 American women in Study II on the health of nurses. The results showed that of the 118 newly diagnosed colorectal cancer cases diagnosed after two decades of follow-up, over an hour in front of the television each day was badociated with a 12% increased risk compared with those who looked less. The results were even more obvious for those who watched more than two hours a day with an increased risk of almost 70%.
According to the study, results were independent of BMI and exercise and were consistently observed in women who did not have a family history of bowel cancer, indicating that sedentary lifestyle may be risk factor quite distinct from colorectal cancer at an early stage. However, the badociation was stronger for rectal cancer than for colon cancer.
This study can help identify high-risk people who could benefit more from early detection, "said Yin Cao, badistant professor of surgery at the University of Washington School of Medicine, and co-lead author of the study.
"A sedentary lifestyle is an emerging risk factor for CRC after the age of 50, but its role in young bad cancer is not known," the researchers wrote.
The authors noted, however, that they did not observe a clear increase in the risk of other forms of sitting at home, such as meals or time spent in front of an office.
Traditionally, colorectal cancer – which is largely preventable – has been targeted only in people over 50 years of age. However, more and more people between the ages of 20 and 30 have been diagnosed with the disease.
