Ways to help reduce your chance of bowel cancer

Cancro intestinale is a general term for cancer that begins in the large bowel. Depending on where the cancer starts, bowel cancer is sometimes called colon or rectal cancer.

Ways to help prevent bowel cancer

More than one half of all bowel cancer cases are preventable, and are generally due to lifestyle. Preventable causes are thought to be the main reason why there has been an increase in the number of 25 - 49 year olds with bowel cancer. Living a healthy lifestyle is more important than ever.

Cancer Research UK says the main causes of bowel cancer and the percentage of people affected are:

• 28% - eating too little fibre.

• 13% - eating processed meat.

• 11% - being overweight or obese.

• 6% - alcohol drinking.

• 7% - smoking.

• 5% - too little physical activity.

• 2% - ionising radiation.

Simple changes to your diet and lifestyle can make a big difference to your chance of getting bowel cancer. And making those changes as early as possible could be key to reducing your risk. Here are six steps you can try to make a real difference.

Reduce how much red and processed meat you eat

Il amount of red meat and processed meat we eat has increased over the past 50 years and long-term consumption of red and particularly processed meat - such as hams, salami, and sausages - may increase your chance of bowel cancer.

You don't need to stop eating red meat completely - it's a good source of protein and iron and can help form a balanced diet - but do so in moderation.

Guidelines suggest we should eat no more than 70 grams a day of red or processed meat - this is around three slices of ham, two rashers of bacon, or one small beefburger. However, there has been much research which links the nitrates put into many processed meats to increasing chances of bowel cancer.

Tip: Try swapping red meat for chicken or fish, have a few meat free days each week and have as little processed meat as possible.

Eat more dietary fibre

Fibre alimentari - also called plant-based carbohydrates - provides a variety of health benefits, including helping your digestive system stay healthy. It may also help prevent you getting bowel cancer.

Esercizio fisico

Alongside changes in your diet, exercise can help reduce your chance of bowel cancer.

More than one half of all people in the UK are overweight or have obesity. Weight issues are a leading risk factor for many preventable cancers. According to Cancer Research UK, each year, 1,900 more people get bowel cancer from being overweight than from smoking.

You should try to do around 150 minutes of exercise a week. Activities such as a brisk walk can lower your chance of many cancers and also provide many other health benefits.

Consiglio: Use our Calcolatore BMI to see if you are a healthy weight or not.

Drink less alcohol

Drinking too much alcohol can cause many digestive cancers and accounts for 6% of people with bowel cancer.

Reducing your alcohol intake is one of the most important steps you can take to help your long-term health. To reduce the health hazards associated with alcohol, you should drink no more than 14 units of alcohol a week.

Tip: Keep track of your units by checking labels and setting a weekly limit.

Consume vitamin D and calcium

Whilst traditionally known for their beneficial effects on bone health, calcio e vitamina D may reduce your chance of bowel cancer.

You can boost your intake of vitamin D and calcium through your diet in ricchi such as fatty fish and a variety of dairy products.

In the UK during autumn and winter the government advises everyone to take a supplement containing 10 micrograms (400 IU) of vitamin D a day to support general health and in particular bone and muscle health. This is because we cannot make vitamin D from sunlight at this time of year.

Tip: Just 10 minutes of sun on your face and arms each day between 11 am and 3 pm gives you enough vitamin D.

Smettere di fumare

A common factor behind many cancers, cigarette smoking is also a long-established risk factor for bowel cancer.

With bowel cancer rates in young adults increasing, the risk is also higher in people who start smoking younger, contributing to this upward trend.

Tip: Read our article on how to quit smoking for helpful ways to stop smoking.

Although changes in your lifestyle are important measures to prevent bowel cancer, one of the most effective steps you can take is to have a bowel cancer screening.

Caught early, bowel cancer is a very treatable disease, leading to a 90 - 95% survival rate. If pre-malignant lesions are detected, cancer can even be prevented.

The NHS offers a home testing kit, which is a simple and effective method to detect possible indications of bowel cancer.

The age at which this is available to you depends on where you live:

• Inghilterra - people aged 50 to 74 years who are registered with a GP.

• Irlanda del Nord - people aged 60 to 74 years who are registered with a GP.

• Scozia - people aged 50 to 74 years with a CHI (Community Health Index) number.

• Galles - everyone aged 50 to 74 years who is registered with a GP and living in Wales.
