Urine test showed a 6.7 psa level, should i accept the recommendation for a prostate biopsy?

Yes unless!: By and large have a biopsy, and hopefully urologist will take at least 12 cores (many don't). Definite have biopsy if your father had prostate cancer. However psa can be elevated with prostatitis or after a vigorous digital rectal examination, in which case wait a couple of weeks and repeat. Prostate cancer is usually very slow growing. Grows slower in older man.

Elevated PSA: The most common cause of a mildly elevated psa is benign prostatic hypertrophy. In 2011 the United States preventive services task force issue a new recommendation against all forms of psa as a screening test. If your age is over 65, you should really not have to worry about this. As a younger man, you may want to check the psa once a year and see a urologist if it goes over 20.

Psa screening: The american urologc association and american cancer society says you need a bx unless you were screened improperly...If you have more than a ten year life expectancy you should discuss a bx with a urologist and then make your decision based on that meeting.

Probably: A blood test with a psa of 6.7 is hi. But other factors need to be taken into account such as your age, overall health, and your 10 year life expectancy. If you are young anf healthy, then a biopsy is usually recommended. As an alternative, active monitoring of the blood in 3 months is also an option but you must closely monitor the psa as it may signify prostate cancer.
