Males have been urged to get tested amid figures which show that fewer men than women participate in a national bowel cancer screening programme.
Statistics show that only 46% of the more than one million people in the scheme since it started in 2007 were men. At the same time almost twice as many cancers have been detected in men than women, with 1813 males and 999 females being diagnosed with bowel cancer through the scheme.
The Scottish Government is re-running a TV advert featuring Still Game star Ford Kiernan speaking to a man sitting on the toilet, encouraging him to take the bowel screening test.
Health Secretary Alex Neil said: "We know that nine out of 10 people will survive bowel cancer if it is detected early. With that in mind, these statistics show the real value of screening, which has led to over 2600 diagnoses of bowel cancer since 2007.
"They also show us that many men are still ignoring this important issue. I hope that re-running this advert will get men thinking about bowel screening which is the most effective way of detecting bowel cancer early. I would encourage all men between the age of 50 and 74 to take the test."
Charles Waddell, 62, a retired deputy headteacher from Ayrshire, credits his successful treatment to taking part in the programme in January 2008. He was diagnosed with bowel cancer in March of that year.
