Hello, I completed my cyberknife treatments about 16 months ago.  After the initial biopsy (before CK), there was dark blood in the semen.  Now it has returned.  Does anyone have a similar experience with this dark coloring of the semen after CK?  My PSA continues to drop (now at 2.09) and no other symptoms to speak of.  I would welcome any response of others per above.  Thanks.

    Blood

    After a biopsy, there can be blood in the semen. This lasts for a few weeks. May also be experiencing side effects from radiation.

    Do bring this up with your Radiation Oncologist. It appears that your seminal vesicals were hit hard...

    thx for your response.  Yes there was after the biopsy.  This is occurring 16 months after cyberknife treatment.

    thx for your response.  I am no longer seeing the radiation oncologist, as my PSA values continue to drop 16 months after cyberknife treatment.  I am trying to find out if others that have had cyberknife have experienced the same issue and for how long after.

    contact the radiaiton ocologist

    ...since it is likely that the blood has resulted due to the radiation

    I am 15 months post Cyberknife and have not had that issue.

    Only time I had that problem was after biopsy prior to treatment as expected.  My PSA is well below 1, glad to know yours is continuing to drop.

    RT side effect

    Hi John,

    This thread is 3 years old and Sonny hasn't shown up ever since. I didn't have Cyberknife but blood in semen is a natural occurrence in radiation therapies administered as prime (CK, imrt, bracky, etc). RP guys who had SRT also experience similar blood excretion occurrence in the urine. 18 months after RT is not considered a late side effect in which case one may expect healing naturally for good. 

    Radiation causes scared tissue at the walls of the urethra where semen and urine pass, leading to bleeding occasionally. This is caused by our body oxygenating the area for healing.

    The situation usually improves with time. Probably Sonny above hasn't experience similar issues ever since.
