Since Allen doesn't have a prostate anymore, what
is left to produce PSA at any level? Just curious - we are completely
greatful for the good results thus far.

Hi Debbie...Congrats to you and Allen on the nice PSA trend! As to
your question, some other organs in the body do produce very small
amounts of PSA. For example, PSA has been found to be present in
epithelial cells of the trachea, thyroid gland, mammary gland,
salivary gland, pancreatic exocrine glands, jejunum, ileum,
epididymis, seminal vesicle and urethra, as well as in Leydig cells
and epidermis pituitary tissue and adrenal tissue. It is also found
in many tumors (e.g. lung, colon, ovary, liver, kidney, adrenal and
paroria). As expected from the above, PSA has also been found in
women. PSA in women can occasionally exceed 0.1 ng/ml depending upon
BCa status, age, time in the menstrual cycle, etc. So while PSA may
be "undectable" with currrent test protocols, it never actually
reaches zero. A felow by the name of "Diamandis" has done a lot of
work on PSA in women and detection of ultra-low amounts of PSA. The
following website will provide more information for the interested
