1/15 USPSTF2021 recs (overturns milestone USPSTF2016) now drop #colorectalcancer (CRC) prevention as a rationale for taking aspirin I think they missed the mark I’ve dug into their evidence synthesis and can expand what I told @nytimes A thread👇🏽 nytimes.com/2021/10/12/hea…

Gastric cancer claims more than 750,000 lives each year. In partnership with @CR_UK, we’ve extended funding for a research dream team that has developed a way to find and stop #gastriccancer at its earliest stages, when treatment is most effective: standuptocancer.org/latest-news/su… @LumicellSurg @MassGenBrigham

Does ultra-processed food increase early-onset colorectal neoplasia risk? @PhyllisWhatsUp's study in young women suggests a strong link. @AndyChanMD @Mengxi_D #EOCRC #Nutrition #CancerEpi #DDW2025

It is an honor to have @AndyChanMD as the Graham-Schwartz lecture speaker for our @BCMDeptMedicine and @tmcddc

A study co-authored by #MassGeneral physician @AndyChanMD was covered by @WebMD. The study found that eating at least two servings of yogurt a week can help prevent colon cancer.webmd.com/colorectal-can…

We're honored to be featured in the Harvard Gazette for our recent journal article on colorectal cancer screening. @MingyangSong3 @AndyChanMD @wangkaiepi @HSPHCancerEpi @HarvardEpi @HarvardChanSPH Our findings have significant implications for personalized healthcare: Individuals with a clean colonoscopy might extend their screening intervals beyond 10 years, depending on lifestyle risk factors and family history. This framework helps refocus healthcare resources on those at greater risk—those who've never been screened and disadvantaged groups with traditionally lower screening rates. We're grateful to the Harvard Gazette for highlighting our efforts.
