Colorectal cancer rates could be reduced by nearly one-quarter if people adopted some lifestyle changes which include watching diet, smoking habits, exercise, alcohol consumption and waist size, Danish researchers wrote in an article published in the BMJ (British Medical Journal). 16,250 people die of colorectal cancer each year in the UK and 38,600 new diagnoses are made annually. Colorectal cancer is the second biggest cancer killer in the UK; it is also the third most common cancer in the country.
According to the American Cancer Society, colorectal cancer is the third most commonly diagnosed cancer in the USA. 49,470 men and 53,430 women are diagnosed with colon cancer every year in the USA, and 22,620 males and 17,050 females are diagnosed with rectal cancer.
Any cancerous growth, lump or tumor of the colon and rectum is a type of colorectal cancer, also known as bowel cancer. According to the World Health Organization, colorectal cancer is the second most common cancer globally after lung cancer. Although it mainly affects older adults, a US study found that rates among younger adults is increasing. Some of the signs and symptoms of bowel cancer may include going to the toilet more frequently, diarrhea, constipation, a lump in the back passage or tummy felt by the doctor, bloating in the abdomen, a feeling that you still need to do more after going to the toilet, blood in stools, a feeling of fullness in the abdomen (even when you have not eaten), vomiting, unexplained weight loss, and fatigue.
The authors explain that there is mounting and compelling evidence linking lifestyle factors, such as diet, alcohol consumption, smoking, and waist size to colorectal cancer risk.
The researchers set out to determine what impact lifestyle and lifestyle advice might have on colorectal cancer risk for middle-aged individuals. They also wanted to see whether bowel cancer (colorectal cancer) risk rose when people did not comply with the advice.
In this study, the investigators examined data on 55,487 individuals aged between 50 and 64 who had no history of cancer. They were monitored for over a decade until 2006. They selected that age group because younger people, especially those under 40 have an extremely low risk of developing colorectal cancer.
They were given a questionnaire to complete which included questions on their general state of health, reproductive factors and lifestyle habits. They were also given a food-frequency questionnaire in order to assess their nutritional habits over a twelve-month period.
