Thank you so much. Very kind of you.
EXCELLENT
Thank you kindly
FABULOUS info - THANK YOU !!!
Happy I can provide value
Hey Dr Ahdoot, thanks for the beneficial video. It would be nice if you could have shown what are the standard psa value and what is elevated and also what role does fPSA plays.
That’s an excellent point. I think I will re do this video with that information added.
@@cancerbetter perfect, I will be looking forward
If your mri shows no cancer.
Do you have to have a biopsy?
Thank You
If an mri shows no cancer.
Do u have to get a biopsy?
Thank You
Hello,
Do you think cystoscopy or BCG treatment can affect PSA and prostate MRI? Thank you.
Yes! Cystoscopy prior to a PSAdraw will elevate your PSA. I recommend you wait a minimum of 10 days after a cystoscopy before you check a psa.
Also BCG can cause changes to be seen in your prostate in MRI. These are not super common but possible.
@@cancerbetter Thank you. I have MRI scheduled in two month after last BCG treatment. Not much can be done.
I’ve had two recent spikes in my PSA level. This past August I went from 2.56 ng/mL to 3.9 ng/mL. Most recently, (Nov. 2022) it went from 3.9 ng/mL to 5.1 ng/mL. Unbeknownst to me (and this is never mentioned by my urologist), that you should be abstinent 24-48 hrs before the blood draw as ejaculation can increase the PSA values. I learned this after my most recent PSA test. I’m very sexually active (be it with a partner or solo), and I know , for a fact, that I had ejaculated 2x within 24 hours of my most recent blood draw (possibly a total of 3, maybe 4 times within 48 hours of my most recent test. In all likelihood (knowing my sex habits) the same occurred back in August.
So my question is, does ejaculation several times prior to a PSA test have statistically significant elevated PSA results?
Another very curious point is that in the 7 years that I’ve been going to my urologist, he’s NEVER performed a DRE on me. What’s with that?
Yes ejaculation with 48 hours prior to PSA testing can increase PSA levels. Try abstaining for a few days and rechecking the level. If you remain in the high 3s, I would discuss and MRI with your doctor.
DRE while a useful test, it only detects about 3% of prostate cancers that would not be detected by PSA alone. This would also be something worth discussing. Perhaps it's time to see a urologist who specializes in Urologic oncology.
My PSA went from 2.1 in Jan 2022 to 230 by April 2023, they retested and got 237 and I'm headed biopsy. My question is: Is there a significance in a 230 vs a 500 vs a 750 ? Or, are they all just outside the range of (0 - 4) and therefore need further testing??
PSA >100 is usually a sign of prostate cancer that has spread beyond the prostate. A biopsy in these situations is usually used to confirm a diagnosis that is highly suspected. There are rare exceptions but usually a PSA this high does suggest cancer and treatment would make people in this situation usually live many years longer.
Also a psa change that dramatic less than 2 years is very unusual.
Can bladder cancer affect PSA?
Usually no. Passing catheters to put medicine in the bladder and cystoscopy to look inside the bladder can though.
@@cancerbetter Thank you. I did PSA test 1 month after TURB. Result is 1.9, in Aug it was about 6 . No idea why. Ultrasound shows some structure in inside area of prostate, outside area is clear. My urologist dismissed my concerns, because 95% of cancer starts in outside area, but it should be a reason for elevated PSA. There was no infection found in urine. Mystery. Anyway, one step at a time. Thanks again.
@vlado3304 there is a condition called granulomatous prostatitis where the BCG itself infects the prostate. Usually it’s not dangerous but can cause something similar to what you describe. Maybe something to look into
@@cancerbetter Thank you very much. Ultrasound was done before BCG treatment.
@vlado3304 then that is definitely not what it is.
