Prostate size

Posted by northoftheborder @northoftheborder, Jun 2 9:12am

Almost 2 years after radiation, my prostate volume was computed via ultrasound to be 13 cc (similar to a ping-pong ball). Normal prostate size for adult men, I think, is 20–25 cc (similar to a medium-sized plum, or a walnut still in its green husk).

In some cases, cancer can cause the prostate to swell to larger than a tennis ball (about 150 cc).

Just a data points for interest. As you were. 🙂

(1 cc = 1 ml)

Interesting.
I'd like to know your age, original PSA, G score, other treatments ... etc.

My prostate volume 45.5 ml by MRI estimated in 2020. (normal 20-30cc by ChatGPT ),
77 y, G 3+3 in one of six biopsies (less than 5% total cells); finished 28 runs of IMRT in March 2024,
ADT has been for 7 months （to be stopped;
original PSA 9.9, now 0.02;

I was 56 at time of diagnosis, and my PSA was 67. It went down to < 0.01 in 3 months after ADT, Apalutamide, and my first round of radiation.

Not sure about my Gleason score, because the cancer had already metastasised to my spine, and the Gleason score is about predicting the risk of metastasising (as I understand it).

My original prostate volume will be somewhere in my old charts, but I do remember them saying that it didn't appear enlarged in the imagery. The aggressive type of prostate cancer (hits young and moves fast) doesn't always give you that kind of warning, like the slow-developing kind most people know about.

Because I'm stage 4b (oligometastatic), there's no expectation that I'll ever stop ADT and Apalutamide either. I find the side-effects a bit unpleasant, but I'm thrilled to have the chance to keep on living.

Anyone knows if prostate size shrinks after radiation and undergoing Hormone therapy(Orgovyx)?

I think it's the radiation that shrinks it, not the ADT, but I'm just a layperson.

I posted this yesterday but now I'm thinking I must of put it in the wrong posting, anyway, after scan it said my prostate was 3.9 cm, not sure what it means. Best to all

I don't know either. If it were perfectly spherical (which it probably isn't), a diameter/length of 3.9 cm would give a volume of about 31 cc, which would be only very slightly above normal, but please don't take that too seriously, since I'm just spitballing.

MRI gives the 3D numbers (for example 4.3 x 3.3 x 3.5 cm). I believe they're the image measured numbers only, not the real size of prostate. Therefore MRI also reports the "estimate" volume adjusted with the specific machine.
