There are some risk factors that may increase the chance of developing this type of cancer. These include:
- Excessive alcohol consumption
- Diet high in animal fat
- Diet containing high amounts of salted, cured, or poorly preserved foods
- A diet low in fresh fruit, vegetables and whole grains
- Chronic pancreatitis
- Increasing age
Based on the known risk factors for GI cancer, there are things you can do to reduce your risk of developing cancer:
- Do not smoke
- Maintain a healthy body weight
- Be physically active
- Eat a diet high in vegetables and fruit
- Limit your intake of alcohol
For more information on nutrition recommendations and recipes, see Nutrition & Recipes
- Being aware of medical conditions that may increase your risk of developing GI cancers
- Having a better understanding of your gastro-intestinal health and learning about the way your body naturally functions so that you can recognise any changes in bowel habits
- Participate in the free Bowel Screening Aotearoa after the age of 60 years (to be rolled out throughout New Zealand by 2020).
What about family history?
Genetic inheritance (family history of cancer) can be a factor in some GI cancers. In some of these cases, screening is available that may help to identify a cancer and allow surgery or treatment at an earlier stage. If you’re aware of a strong family history of GI cancer, discuss this with your GP.
