Tumour dissemination

The prostrate biopsy releases a lot of blood into urine, semen and presumably the bloodstream. If a slow growing cancer contained in the prostrate is released and travels through the blood would this not increase the risk of contracting metastatic cancer in the bones and other vital organs?

I did bring this up with my Specialist Nurse but she poo pood this theory. What are others thoughts on this?

Prostate cancer cells are transported by tissue / lymphatic fluid not blood. The alleged cases of metastatic spread from biopsy were to do with needle tracking not blood transfer.

The incidence of needle tracking following either a TRUS or TPM biopsy is considered to be extremely rare. I researched this prior to having my own TPM biopsy and the below link was the latest information that I could find on this.

I did say ‘alleged’ but the data seems to suggest it is slightly less rare with template biopsy than with TRUS .... and slightly more feasible than cancer being spread via blood in the urine.

Some doctors do believe that PCa cells can also be carried through the body in blood. I did watch a video lecture on this once how the route made it possible and will post it if I can find it. Meanwhile, a quick google check refers to this : - 'Prostate cancer can spread through blood or lymph fluid and form tumors in other parts of the body, including the brain, lungs, liver, spine, and bones......' from https://www.menwhospeakup.com/downloads/PP-600-US-2374_Unbranded%20Patient%20Brochure_2016.pdf

But that is blood circulation, not blood in the urine as a result of biopsy :-/

if prostate cancer cells were being transported round the body via the circulatory system, the medics would presumably be able to find it in blood tests and we would no longer need PSA tests?

I was responding to the comment ....'and presumably into the blood stream' and prostate cancer cells were 'not transported by blood'. There is a process whereby dislodged cancer cells can be introduced into veins, particularly if punctured and be carried back to the heart and thence to lungs and onwards to eventually reach remote parts of the body. This was well explained by a British Dr who had been working in the USA for over 20 years but it formed part of a wide ranging lecture and I can't find his video now. It is interesting that apart from the dubious PSA tests, research and trials are underway to more positively test blood to determine whether it shows for PCa. Not a precise indicator but this sort of research gives an idea of what is being worked on to help show men with likely PCa. Hopefully, before very long a way will be found of more positively identifying PCa through a blood test. https://www.telegraph.co.uk/science/2018/01/17/blood-test-confirms-prostate-cancer-could-prevent-70-biopsies/

This goes rather beyond what the OP mentioned but is an interesting development.
