cancer spread via biopsy?

I think this subject has come up before but I can`t locate it.

A very good friend of mine has recently been diagnosed with cancer of the lower colon and rectum. He had a biopsy about 21/2 years ago  about the same time as mine. He was dx`d Gleason 7 ( 3+4) PSA 10.7. He has been doing well (PSA <.1) after a DiVinci proceedure.

Is there any evidence that removing the cores containing cancer cells can spread the cancer to the colon and rectum as the needles are withdrawn? It seems to me that it may be possible but rare.

i have seen this come up before here and I seem to recall the answers always stating that there is no proof of this

There may be no proof, however, there is a chance.
I've read somewhere about metastasis through biopsy.
I'll have to look in my research folder.

I have to believe it is entirely possible......loose cells are loose cells.

My homeopathic consultant swears that biopsies can dislodge cancer cells, every medical doctor I've asked says there is no evidence.

Worry more about getting an infection from the biopsy.

If you're going to worry at all about it.

142 has the answer to this question in this specific case, cut and dry. If the cells in colon and rectum are pca cells, voila. If not , not in this case. I would say jury is out ,b ut don't think a jury has ever been seated. I think , not sure, that some specialists allow for the possibility of pca being spread via sex , in that male sperm could contain pca cells. who knows. Cost benefit analysis needed?
