TODAY'S TOPIC
Lung Cancer Screening
|
| How many Americans who qualify for lung cancer screening actually get screened? Estimates run between 15% and 20%. |
|
CLAIM 01
“If you quit smoking more than 15 years ago, you are finished with lung cancer screening.”
|
| VERDICT IT'S COMPLICATED |
|
Fifteen years is still the cutoff in the US Preventive Services Task Force recommendation. It is no longer the cutoff in every major guideline. The USPSTF recommends annual low-dose CT for adults ages 50 to 80 with at least a 20 pack-year smoking history who currently smoke or quit within the past 15 years. A pack-year means one pack per day for one year, so one pack a day for 20 years equals 20 pack-years. The American Cancer Society now recommends annual LDCT for adults ages 50 to 80 with at least 20 pack-years who smoke or used to smoke, without a years-since-quitting cutoff. Eligibility now depends on which guideline your clinician or insurer follows. |

WHERE THE EVIDENCE SPLITS
|
● What would you do with 84 extra minutes of sleep?
What would you do with an extra 84 minutes of sleep tonight?
Wake up before the alarm without feeling like you've been hit by a truck? Get through the afternoon without a third coffee? Actually enjoy your evening instead of counting down to bedtime?
That number isn't random.
It comes from a small pilot study at Louisiana State University.
Researchers worked with adults over 50 who had been struggling with insomnia. For two weeks, half of them drank tart cherry juice in the morning and again before bed. The other half got a look-alike drink with no cherry in it.
Then everyone spent a night in a sleep lab, hooked up to monitors that track exactly how long you're asleep.
The cherry group slept an average of 84 minutes longer.
It was a small study, and the researchers say more work is needed. But it added to a growing body of research on tart cherries and sleep, and it's a big reason these little red fruits keep coming up in conversations about natural sleep support.
Part of the reason may be that tart cherries naturally contain melatonin, along with plant compounds that may help your body make better use of tryptophan, one of sleep's key building blocks.
If you'd like to try it yourself, there's a simple 30-second cherry routine you can fit into your evening.
No prescription. Nothing complicated.

CLAIM 02
“Annual low-dose CT screening lowers lung cancer deaths in people at high risk.”
|
| VERDICT TRUTH |
|
This is one of the better-supported claims in cancer screening because the benefit has been tested in large randomized trials. The National Lung Screening Trial found about 15% to 20% fewer lung cancer deaths among high-risk participants screened with low-dose CT compared with chest X-ray. That translated to roughly three fewer lung cancer deaths per 1,000 people screened over about seven years. The USPSTF concluded that annual LDCT can prevent a substantial number of lung cancer deaths in people at high risk. This is screening before symptoms appear, not a diagnostic CT after symptoms begin. |

CLAIM 03
“Most Americans who qualify for lung cancer screening get screened, as with breast and colon cancer.”
|
| VERDICT MYTH |
|
Lung cancer screening reaches only a small share of the people who qualify. A nationally representative analysis of 2024 data found that 18.7% of screening-eligible adults were up to date with lung cancer screening. That is roughly one in five. Uptake remains far below screening levels for several other common cancers, even though annual low-dose CT has evidence showing that it can reduce lung cancer deaths in high-risk populations. The screening tool exists. The bigger gap is getting eligible people to it. |

WHAT DOES SCREENING ACTUALLY INVOLVE?
A low-dose CT takes only a few minutes.
The CDC explains who should be screened, what the scan is like, and why screening is different from testing symptoms.

THE BOTTOM LINE
The tool exists, and the evidence behind it is strong.
The gap is in who gets offered it.
