These "interventions" by David Cameron and Rishi Sunak however well intentioned are now verging on irresponsible. There is good reason why activism even by ex PMs should not dictate national screening decisions. As a surgeon, researcher and recent health minister I'll explain why...... Screening for any disease is not a risk and harm free exercise both in terms of harms of the test itself and the complications of unnecessary treatment. That is why they are carefully balanced decisions based on whole populations not individual case studies as emotive as they might be. Current studies and evidence from international trials in prostate cancer are not representative of the UK population which has higher numbers of black men who are indeed at higher risk of prostate cancer but need evidence and data tailored to their needs. What we need is better modern screening tools rather than a blanket application of suboptimal tests which may miss cancers and lead to unnecessary treatment. And there is a clinical trial ready to answer exactly these questions set up by some of the brightest minds in the UK and backed by the @NIHRresearch and @ProstateUKVoice prostatecanceruk.org/researc… So please do use your activism to push politicians and researchers to answer these questions faster, to break the mould, to push the boundaries to get the science done. But do not inadvertently become complicit in an uncontrolled screening experiment of men and black men because of your desire to do “something”.
Today’s recommendation from the National Screening Committee on prostate cancer screening is deeply disappointing and a real step backwards. I urge the new Health Secretary to reject it and go further - offering targeted screening for the most at-risk men. As I warned last November following the initial advice, prostate cancer is the most common cancer among British men. We are letting down too many men, their families and loved-ones if we don’t push for a wider screening programme that includes all high-risk groups. Prostate cancer can be symptomless early on - as it was in my case. That’s why screening is essential - catching the cancers early when they can be more effectively and successfully treated, like with me. If the advice is to be followed, you could be an older, black man with a family history of prostate cancer and STILL not get routinely screened. Surely, that can’t be right? There are now better screening options and more advanced focused treatments available in parts of the NHS. I benefitted from these and others could too. Yet this seems to have been ignored by the Committee. The new Health Secretary needs to be brave and bold. A more progressive and life-saving policy is within our grasp. Put in place a proper, targeted screening programme that involves all those at higher-risk. Without it, more men will die, and more families will lose a loved-one. As I said in November, this is avoidable and can be done.

A great honour to speak at the Association of Surgeons of Great Britain and Ireland, especially under the presidency of my friend @SurgeryHPB . A great meeting, enjoyed by all the delegates: domestic, Chinese and canine! Looking forward to next year's meeting in Manchester.

If outcomes equal, then the more cost effective one.
Two junior faculty, equally productive (excellent outcomes), one uses way more technology. Lap vs robotic chole?

Vocational aspirations and society expectations will always collide. It is the journey that matters indeed. Surely it gets better if there’s a bit more money there

Appreciate the shout out and agree with the sentiment. The challenge we were hoping to convey / focus on is when trainees feel compelled to extend the journey with gap years/research/fellowships they don't want or ultimately won't need... the $ costs are real to these decisions

Hyperbolic nonsense and weak virtue signaling at its finest 🤦🏾‍♂️
Interesting, but sad if your decision to do anything in life is based on "retirement funds and home equity". It's the journey that matters, not the destination. Every minute of my (long) surgical training was valuable. #Surgery

Viewpoint: Delayed start to surgical practice by 1 or more years was associated with significant reductions in lifetime earnings, retirement funds, and home equity. @drdevirgilio ja.ma/4qaBBYb

I used pericardium as pledgets on several occasions for stab hearts (it works ) I think we should teach the technique to young trauma surgeons @alsufyani_ahmed
