February 2003 From BMJ-British Medical Journal Lavatory disinfectants may hinder colon cancer programme Letter: Look before you flush BMJ Volume 326, p 397 Coloured lavatory disinfectants might be hindering the national programme for early detection of colon cancer, suggests a letter in this week's BMJ.The programme advises people "don't blush�look before you flush" to raise public awareness of rectal bleeding � often an early sign of colon cancer. Yet Mourad Habib, a clinical research fellow at St James's University Hospital, says that the lavatory disinfectants now sold in supermarkets are mostly blue in colour and change the water blue, which makes looking for blood quite difficult. He suggests that we stop selling colouring agents and replace them with colourless ones or even use reagents that turn a certain colour in the presence of minor blood amounts. |
