I certainly favor having patients getting a scan with that, acknowledging though that I don't have amazing data to point to, to say that the 25 millisievert one versus, just to make the math easy, the 2.5 millisievert one, tenfold difference, poses any difference in risk. Exactly. How do you think about that?

What would be your confidence in saying that 2.5 is not actually better than 25 from a cancer risk standpoint?

So in other words, you're saying, I don't really care if it's 25 or 2.5 as well. And the good news is these brand new scanners are faster, which is why they're giving you less radiation. Exactly. they seem to have better resolution.

So what should people be thinking about in terms of extraneous radiation? When should people be saying to their doctors, hey, do I really need this? For example, when you go to the dentist every year, they typically want to do a set of x-rays. Is that anything? thing people should be worried about?

By the way, just on the PET scan. So if you do a PET CT, for example, which again, these are not routinely done. These are typically done in oncology patients only. But just for my own understanding, are we talking 50 to 100 millisieverts if you're doing a whole body PET CT?

So now let's pivot from the diagnostic to the therapeutic. Is it safe to say that the majority or the most prevalent or common type of radiation oncology treatment would be for breast cancer?

Well, let's talk a little bit about breast cancer, given how common it is. I'll tell you something funny. Despite training at Hopkins, I never once did a radical mastectomy. I mean, it was already long gone from clinical practice 25 years ago.

And again, just for listeners to make sure they understand the difference between a radical mastectomy and a mastectomy, or what's called now a modified radical mastectomy. The current version of a mastectomy removes all the breast tissue along with the lymphatic tissue in the axilla.

Certainly, I did more than my fair share of those, but the radical mastectomy, the Halsteadian procedure, removed also the entire musculature of the pec, pec major, pec minor, the whole thing. It basically was a disfiguring operation- debilitating, disfiguring. With nothing but ribs. Imagine what it's like to not even have pec muscles.

You sort of take for granted what you need to do to move your humerus. And yeah, to think that it's only been 40 or 50 years that someone had the courage, I think it was probably Fisher. Right.
