A patient who never smoked, never drank, and was fastidious about his diet died of cancer at 49. That patient was my father. He went to his grave not knowing he actually carried a genetic mutation that caused his fatal tumor. Virtue doesn't necessarily guarantee health. RIP Dad

It's easy to recommend exercise for better overall health but I had a truly remarkable day in clinic empowering patients with colon cancer to follow an evidence-based, post-op fitness program that offers a survival benefit on par with some chemo drugs. Bodies in motion, indeed!

A timely reminder that there are many variables to consider in optimizing outcomes from cancer, even potentially the timing of infusions during the day. But post-#ASCO25 we are better poised than ever to empower patients about their own agency by prescribing “exercizumab” #crcsm.

At #ASCO25, research emphasized exercise, diet, and timing of immunochemotherapy as key to improving colon cancer outcomes, and called for a focus on survival and quality of life in clinical trials. @KimmieNgMD .

Every doctor carries within themselves a small cemetery, where from time to time they go to pray . In my case it’s literal; this morning I stopped where far too many of my patients are interred . They are not forgotten and their memory inspires me to care better in the here & now

I needed to have that difficult conversation with my teenager this evening (the one where I explained that you have to let Kid A grow on you and not just write it off immediately because there are way fewer guitars).

Oncologists absolutely “shout at the crops” and prefer they not grow quickly.

10. IT GETS BETTER. Even though we no longer live in the hospital for “residency” it can still feel like that at times . A wise friend told me “every call must end” and that’s true of training as well. It’s a crucible, yes, but it forges confidence & acumen.
