Today Puzzle #668
Puzzle No. 668 鈥� Tuesday 4 February 2020
Today is World Cancer Day. There are 363,000 new cases diagnosed every year in the UK. 81% of those who are diagnosed early survive their cancer for at least five years after diagnosis compared with only 26% for those diagnosed late. Each year, how many more people will survive their cancer more than 5 years if the proportion diagnosed early is increased from 50 to 75% (in line with the Government’s Strategy)?
Today’s #PuzzleForToday has been set by Dr Shaun Fitzgerald, Fellow of Girton College and Rebecca Fitzgerald, Professor of Cancer Prevention at Cambridge University.

The additional number of people who will be diagnosed early each year is 25% x 363,000 = 90,750. 81% of these will survive their cancer for at least 5 years, although 26% would have survived this time anyway had they been diagnosed late. Therefore (81% - 26%) x 90,750 = 49,913 more patients each year will survive their cancer 5 years.
