Any thoughts on the cancer screen they’re always trying to upsell?

Careful: the stats you're reading are all-cancers, cancers aren't uniformly prevalent, and the specific cancers you're referring to might (and probably do) have much, much worse screening outcomes than the aggregate.

For someone who has no medical background, you are certainly spouting a lot of nonsense as if it was fact.The WHO, for example, disagree.https://www.who.int/activities/promoting-cancer-early-diagno...

Most cancers are a lot more treatable if caught early. Sometimes you can just cut it out and never relapse if caught early enough before it metastasizes. Screening is worthwhile.

Can confirm.Due to late/lazy screening, my cancer was caught late and now I'm fighting an uphill battle.It doesn't seem like rocket science to screen early but also not over-treat.

early detection is great, if you're being specifically checked for cancer. the problem is that you can have tumors growing inside you for years, and during that time, the effects of those tumors may lead your doctor to misdiagnose the problem. And by the time those tumors make themselves painfully obvious, you've got Stage 4 cancer which is pretty much a death sentence.In the US you can order your doctor to arrange a cancer screening for you (scan or blood test), if you are worried

For cancer screening? That doesn't make much sense.

You would need to take into account how aggressive a given cancer is and our ability to treat it.For instance, prostate cancer blood screening often led to radical treatments that are no longer thought to be worth it for most people.> most prostate cancer grows so slowly, if it grows at all, that other illnesses are likely to prove lethal firsthttps:&#x

A counterpoint to these stories of early diagnosis is that not all cancers are equal, and there are some cancers which may not ever have affected the patient had they not been treated (or detected). Examples include some prostate and breast cancers. Autopsy studies have shown occult prostate cancer in about half of men > 70 years old who were asymptomatic and died of other causes.Of course it is often impossible to know which cancer will or won't kill you, but it should be recognized

I was diagnosed with a cancerous tumor less than a year ago. It is a tumor that has been growing inside me for at least 5 years. Had it been correctly detected/diagnosed 5 years ago, it would have been an operable tumor with a high chance of a cure rate. Unfortunately, now that tumor is currently non-operable.Current cancer screening guidelines aren't sufficient and in almost all cases they utterly fail in the early detection of cancers for people under the age of 50.I applaud a
