@surftohealth88 Nice photos...not sure what you mean referencing "drive through" labs unless you were being pejorative. There is of course no such thing as a "drive through" lab.
"Long tissue samples" is a relative term. One of the first things a urologist will note is the "length" of the core sample when expelled into the jar of formalin. Per the literature on the subject, the typical core is about 11.3 mm (0.44") long because the prostate is only the size of a walnut: 4cm x 3cm x 2cm (1.6" x 1.2" x 0.75"), therefore, a 0.44" core has traveled through almost half of the prostate. And...(interestingly)...
Per the literature, core biopsy "length" is actually an initial quality assurance reflection of the probability of cancer being present or not. While the size of the cancerous prostate is often bigger (tumor occupies more space in the slightly enlarged prostate), prostate size is not a definitive, diagnostic criteria for cancer. Size is however, a reflection of patient age though, as the older a man gets, the larger his prostate is. But...apparently, it is generally accepted within the world of urologists and pathologists, that a core length size of >11.9 mm (greater than 0.47") is highly suggestive of cancer. Anything less is not definitive, and cancer cannot be completely ruled out, but is apparently less a likely probability than the slightly longer cores.
Interesting stuff. The "passion" on the subject offered by "@surftohealth88" in this post, got my curiosity up to look into core length. I knew (had a very good hunch), that the length of the cores could not be very long, just based on the small size of the prostate itself. I initially guessed 1/2" - 3/4". I learn something everyday.
