The Skeptics' Guide to the Universe
The Skeptics Guide #1087 - May 9 2026

Because when we're talking about individuals over 75...

The Skeptics' Guide to the Universe
The Skeptics Guide #1087 - May 9 2026

there are more medical complications, and there are fewer years just from a statistical perspective of living.

The Skeptics' Guide to the Universe
The Skeptics Guide #1087 - May 9 2026

And so, you know, the study authors basically said, even if the procedure goes well, you're either going to find something...

The Skeptics' Guide to the Universe
The Skeptics Guide #1087 - May 9 2026

or not but if you do find something it may not have a real impact on your longevity and would these individuals be moving forward and having other kind of invasive medical treatments that could have side effects that outweigh the the slow growth of the disease there as my dad put it when he first found out that he had early stage prostate cancer and you know did have his prostate removed

and without complication, luckily, his physician told him, most men will not die of prostate cancer, but most elderly men on autopsy will have some slow growth in their prostate.

And so these are the other two that they describe here are a treatment for a skin condition called actinic keratosis, which causes like red patches often on the face or scalp because it it reacts with the sun.

The Skeptics' Guide to the Universe

It results from long term sun exposure.

The Skeptics Guide #1087 - May 9 2026

And most of the time people choose to remove them.

The Skeptics' Guide to the Universe
The Skeptics Guide #1087 - May 9 2026

And there was a large study that showed that Medicare beneficiaries, so we're already talking over 65, over a five-year period, almost 30% of people were diagnosed with actinic keratosis.

The Skeptics' Guide to the Universe
The Skeptics Guide #1087 - May 9 2026

So that study didn't say how many people had it removed, but it's almost a third of the population of Medicare recipients were diagnosed with this.

The Skeptics' Guide to the Universe

Many people do end up getting them removed via cryosurgery or laser therapy.

And the rationale there has been historically that these patches could become cancer.

The Skeptics' Guide to the Universe
The Skeptics Guide #1087 - May 9 2026

But the rate on further review is less than a 1 in 1,000 chance.

The Skeptics' Guide to the Universe
The Skeptics Guide #1087 - May 9 2026

Less than a 1 in 1,000 chance that these patches would progress to skin cancer.

The Skeptics' Guide to the Universe

Much more often they just disappear on their own.

And so the study author said, you know, the treatment can be more burdensome than the condition itself.

The Skeptics' Guide to the Universe
The Skeptics Guide #1087 - May 9 2026

It's very painful.

The Skeptics' Guide to the Universe
The Skeptics Guide #1087 - May 9 2026

It can cause swelling, irritation, and it can cause lasting discoloration.

The Skeptics' Guide to the Universe
The Skeptics Guide #1087 - May 9 2026

And even beyond that, actinic keratosis will often reappear.

The Skeptics' Guide to the Universe
The Skeptics Guide #1087 - May 9 2026

It's a chronic condition.
