Rules:

Rule 1: posts have the following requirements:
- Post news articles only
- Video links are NOT articles and will be removed.
- Title must match the article headline
- Not United States Internal News
- Recent (Past 30 Days)
- Screenshots/links to other social media sites (Twitter/X/Facebook/Youtube/reddit, etc.) are explicitly forbidden, as are link shorteners.
Rule 2: Do not copy the entire article into your post. The key points in 1-2 paragraphs is allowed (even encouraged!), but large segments of articles posted in the body will result in the post being removed. If you have to stop and think "Is this fair use?", it probably isn't. Archive links, especially the ones created on link submission, are absolutely allowed but those that avoid paywalls are not.
Rule 3: Opinions articles, or Articles based on misinformation/propaganda may be removed. Sources that have a Low or Very Low factual reporting rating or MBFC Credibility Rating may be removed.
Rule 4: Posts or comments that are homophobic, transphobic, racist, sexist, anti-religious, or ableist will be removed. “Ironic” prejudice is just prejudiced.
Posts and comments must abide by the lemmy.world terms of service UPDATED AS OF 10/19
Rule 5: Keep it civil. It's OK to say the subject of an article is behaving like a (pejorative, pejorative). It's NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect! This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.

Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.

Rule 6: Memes, spam, other low effort posting, reposts, misinformation, advocating violence, off-topic, trolling, offensive, regarding the moderators or meta in content may be removed at any time.
Rule 7: We didn't USED to need a rule about how many posts one could make in a day, then someone posted NINETEEN articles in a single day. Not comments, FULL ARTICLES. If you're posting more than say, 10 or so, consider going outside and touching grass. We reserve the right to limit over-posting so a single user does not dominate the front page.

We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

'These are people in the prime of life': The worrying puzzle behind the rise in early-onset cancer (www.bbc.com)

Over the past 10 years, rates of colorectal cancer among 25 to 49 year olds have increased in 24 different countries, including the UK, US, France, Australia, Canada, Norway and Argentina.

The investigation's early findings, presented by an international team at the Union for International Cancer Control (UICC) congress in Geneva in September 2024, were as eye-catching as they are concerning.

The researchers, from the American Cancer Society (ACS) and the World Health Organization's (WHO's) International Agency for Research on Cancer, surveyed data from 50 countries to understand the trend. In 14 of these countries, the rising trend was only seen in younger adults, with older adult rates remaining stable.

Based on epidemiological investigations, it seems that this trend first began in the 1990s. One study found that the global incidence of early-onset cancer had increased by 79% between 1990 and 2019, with the number of cancer-related deaths in younger people rising by 29%. Another report in The Lancet Public Health described how cancer incidence rates in the US have steadily risen between the generations across 17 different cancers, particularly in Generation Xers and Millennials.

Recently I went to Seattle's children's museum and when it was about to close I found my self staring at the cosmic particle fog tank. It's a tank that has low temperature evaporated alcohol in it which creates wisps of fog if highly energetic particles pass thru it. Well I didn't know what it was until I started noticing the wisps and remembering a YouTube video in the device. It was like a wisp every 10 seconds. Suddenly this family passed by and the little 3 or 4 year old kid approaches the box to see what was in it. The thing lit up like a freaking Christmas tree. Like 10 wisps per second as soon as the kid put his hands on the side of the glass. I looked at him thinking, you don't know, just live out your life in happiness kid.

That’s wild. Wonder why child was extra radioactive

[–] werefreeatlast 12 points 2 months ago (1 children)

I was totally bewildered. I should have run to the parents to show them. It was just crazy. Maybe they gave him a hammer and a bunch of smoke detectors the day before.

[–] GreenKnight23 14 points 2 months ago (1 children)

possibly leukemia and what you were seeing is the effects of treatment...

fuck all cancer.

[–] werefreeatlast 11 points 2 months ago (1 children)

Oh yeah, what if he had cancer treatment recently! That could have been? Or tracer fluid for MRI.

[–] [email protected] 8 points 2 months ago (1 children)

would be an injectable radiation therapy or a radiotracer for a PET or SPECT scan. afaik radioactive tracers aren't used in MRI or regular CT scanning

[–] werefreeatlast 3 points 2 months ago (1 children)

A radioactive tracer can be used in a PET/MRI scan, or a gadolinium-based contrast medium used in an MRI scan. But I think you're right about MRI not actually requiring a tracer.

[–] [email protected] 2 points 2 months ago

MRI sometimes uses a non-radioactive contrast depending on what you're trying to get images of. MRI is probably the safest imaging modality, but it's very expensive, kind of difficult sometimes due to how long it takes, and isn't useful for every kind of imaging that needs to be done.
