Risk factors are of two types; non-modifiable and modifiable. Non-modifiable risk factors are risk factors that cannot be changed such as age and heritability etc. Modifiable risk factors are risk factors we can change such as our diet, lifestyle and environment.
Non-modifiable risk factors:
- Age: cancer risk increases with age.
- Genetics: some families have a higher risk for certain cancers.
- Abnormalities/mutations of genes increase the risk of cancer. (e.g. HER2 oncogene increase the risk of breast cancer)
Modifiable risk factors (following habits and exposures increase the risk of cancer):
- Alcohol consumption above the safe limit.
- Diet: consumption of high fat, low fibre, red meat and processed meats.
- Infections: e.g. Helicobacter pylori increase the risk of stomach cancer, human papillomavirus increases the risk of cervical cancer, hepatitis B increases the risk of liver cancer
- Radiation and sunlight: exposure to ionizing radiation and UV radiation from sunlight.
- Hormones: e.g. treatment with oestrogen (oestrogen containing oral contraceptive pills) can increase the risk of breast cancer.
- Tobacco smoking.
- Betel chewing.
In addition to the above factors, there are many other risk factors related to cancer.
