Cancer affects more than one in three people during their lifetime.
Changes to the body’s normal processes or unexplained changes could be early signs of cancer.
Making simple changes to your lifestyle could lower your risk of developing the disease, according to the NHS.
But, eating just three portions of wholegrains day could cut your risk of cancer by as much as 17 per cent, scientists have claimed.
“Replacing some of your refined grains with wholegrains and eating mostly plant foods, such as fruit, vegetables and beans, will give you a diet packed with cancer-protective compounds and help you manage your weight, which is so important to lower risk,” said Alice Bender, American Institute for Cancer Research’s Director of Nutrition Programmes.
“When it comes to cancer there are no guarantees, but it’s clear now there are choices you can make and steps you can take to lower your risk of colorectal and other cancers.”
Eating 90g of wholegrains everyday could lower your risk of bowel cancer by 17 per cent, scientists revealed.
Processed meat, including bacon and salami, could raise your risk of bowel cancer, they also claimed.
Bowel cancer is common, but about 45 per cent of cases could be prevented by making subtle lifestyle changes, researchers said.
Maintaining a healthy weight is important for preventing bowel cancer, and 10 other common cancers.
Wholegrains – such as brown rice and whole-wheat bread – could contribute to lowering your risk of the condition.
They contain fibre, B vitamins, folic acid and antioxidants.
Finding blood in your stools could be a sign of bowel cancer.
Other symptoms include a persistent change to your bowel habit and persistent bloating.
You should see a GP if your symptoms keep coming back, said the NHS.
Almost 90 per cent of bowel cancer cases occur in people over 59 years old.
