It may not be significant enough to cause any symptoms or it may be such a problem that treatment is necessary. There can be symptoms of increased frequency, inability to completely empty the bladder, having to get up several times at night to urinate, etc. There are some medications that can be used to reduce these symptoms. There are several surgical options. Patients need to be evaluated by a urologist to assess what treatment is appropriate for them.
Some medications can actually reduce the size of the prostate.
Finasteride or Proscar works in this way. Other drugs work by relaxing the muscles. Surgery to remove the prostate, a radical prostatectomy, is done to remove the cancer. There are nerves that run along each side of the prostate that control erectile function. When the prostate is removed the nerve bundles are removed.
