How to Prevent Cancer

People do not “catch” cancer from someone else as it is not contagious. However, cancer develop due to lifestyle factors like smoking (or inhaling second-hand smoke), consuming alcohol excessively, consuming too much fat, over-exposure to sunlight, radiation, or industrial chemicals. As such, avoiding these risk factors can help in avoiding cancers.

Avoid Smoking and Cigarette Smoke

While movies in the past had often romanticised smoking, the reality is that there are around 40 different carcinogenic substances in cigarette smoke, and it is the number one risk factor for lung cancer. It is found that most lung cancer sufferers are smokers.  Besides lung cancer, smoking can cause mouth, throat, larynx, oesophagus, stomach, pancreas, kidney and bladder cancer too. The same applies for second-hand smoke too, so non-smokers should find ways to protect themselves and avoid inhaling second-hand smoke as much as possible.

It might not be easy, but here are some steps you can take to help you to quit smoking:

  • Enlist the support of friends and family, or join a programme or support group, to support your efforts to quit
  • Discard your cigarettes and lighters.
  • Spend more time with non-smokers in smoke-free environments.

Eat More Fresh Fruit and Vegetables

Fibre and vitamins found in fruits and vegetables can reduce the risk of cancers colorectal and stomach cancers. Furthermore, they can even reduce the risk of breast cancer. On the other hand, processed foods (e.g. ham, bacon) and even salted or preserved food (e.g. pickled vegetables) contain chemicals that could increase the risk of cancer when taken excessively.

Consumption of improperly stored food could also increase the risk of cancer. For instance, peanuts, seeds and grains that have turned mouldy contain substances that can cause liver cancer.

To lower the risk of cancer:

  • Eat fresh fruit and vegetables at every meal;
  • Consume a variety of fruits and vegetables so that you get a variety of different minerals. Dark-green leafy vegetables and orange-yellow fruits in particular are good. Do not overcook vegetables as this could destroy the vitamins in them;
  • Eat wholemeal bread or wholegrain cereals for their fibre;
  • Avoid or reduce intake of salted, pickled, preserved and processed foods;
  • Prevent nuts and grains from becoming mouldy by storing them in air-tight containers.

  • Remove fat from meat and skin from poultry before cooking, and avoid fats when eating;
  • Stew, bake, steam or boil instead of deep-frying your meals;
  • Choose skimmed milk, reduced fat cheese or low-fat yoghurt instead of full fat options. Also, reduce intake of sugar in soymilk, coffees and teas. 
  • If you must snack, go for fresh fruit or wholemeal crackers. 

Do Not Consume Alcohol Excessively

Consumption too much alcohol increases the risk of liver cancer, and also cancer of the mouth, throat and oesophagus.

If you do consume alcohol:

  • Limit the consumption to two standard drinks or less a day. A measure of a standard drink is approximately one can of beer (285ml), one glass of wine (120ml), or one measure of spirits (30ml);
  • Alternating alcoholic drinks with non-alcoholic ones and drink them slowly can help reduce the amount consumed each time.

  • Taking cover behind protective shields or staying in “safe” areas;
