Around the world many people are worried about the causes of cancer and some will look at common myths rather than the facts.
But today marks World No Cancer Day and the message for this year, according to the Union for International Cancer Control, is to give cancer myths a miss.
Cancer Council Western Australia director of education and research Terry Slevin said cancer myths could distract from dealing with the well-established causes of cancer.
These are being overweight, excess alcohol consumption, tobacco smoking and exposure to ultra-violet light.
According to Cancer Council WA, at least half of all cancers could be prevented with a healthy lifestyle and avoiding these risk factors.
