This is an open letter from me to World Leaders about cancer. If we truly want to beat cancer sooner, we need to cooperate across the world to use our money, knowledge and skills more wisely - for public benefit, not for profit.
I know this is a contentious area. Lots of doctors don't like using the PSA test because it's unreliable and can lead to over-diagnosis and over treatment. But at present it is the best thing men have got. And our clinical consensus will help GPs to use it more effectively.
When we look back on this time in history, we will not be proud that we made record profit margins from cancer drugs while one person died of cancer every four seconds, but we can be proud by making a stand to change this.
The current system for developing cancer drugs depends mostly on private investment from pharmaceutical companies and, as investors demand good returns on their investment, it's no surprise that what we've ended up with is very profitable drugs rather than very effective ones.
The 4th February 2016 was World Cancer Day - a day to reflect on how cancer impacts our lives. I'm sure that many of us, including me, will be thinking about loved ones we've lost or who are living with cancer right now, but it's also a time to think about what we could do to bring forward the day when we no longer live in fear of cancer.
The previous Government set a measly target to bring the UK up to the average survival rates for Europe; an increase of just 3% after 5 years. How can we achieve a breakthrough in the battle against cancer when our aim is to do no better than other countries are already doing? And meanwhile, other countries are probably investing more, setting more ambitious targets and forging even further ahead.
