Don't skip your doctor visits or recommended screenings boys.

This is probably 90% of men. But the five-year survival gap between localized and metastatic cancer can be enormous.

91% vs. 17% for colorectal cancer
66% vs. 11% for lung cancer

Getting checked early can completely change the odds

@SaffronOlive They chose the wrong Khan.

@NotebookLM @googledrive Will we be able to export sources in a generally accepted citation format like APA, MLA or IEEE?

[Jacob Koster, MS, MPH @bioguy9]

@SaffronOlive Seems possible but be prepared for a lot of data entry considering reprints across sets.

[Jacob Koster, MS, MPH @bioguy9]

@erscrofano Very nice but we should be able to see them televised locally.

It's incredibly lame that none of the local Boston TV channels are airing the Boston fireworks.

[Only In Boston @OnlyInBOS]

As lightning delayed the Boston Pops Fireworks Spectacular tonight, hundreds of people sheltering under a tunnel on Storrow Drive sang "America the Beautiful" together.

Possible. The main ways Hep B spreads is by mother to baby during birth or sexually later in life. Waiting on vaccination might be ok if it still happens before sexual activity begins. But delaying won't protect newborns against undiagnosed infection in the mother.

[unusual_whales @unusual_whales]

"The Trump administration’s move to drop the long-standing recommendation for newborn hepatitis B vaccination within 24 hours of birth will likely lead to additional infections and millions in added health care costs," per WaPo
