A few quick thoughts -

Go see another doctor, one who specializes in this AND the operation. If both test show similar results, then the decision will be made by you and your doctor(s).

While prostate cancer is easily 'cured' if caught early, it does have some serious down-sides. IF seeds are an option (honestly, 7 of 12 is pretty high - you may not want to risk it spreading to other organs, like your bladder), that is an option to seriously consider because -

there is NO turning back when removed. Removal will more than likely solve the cancer issue, but there is a cost. If you opt to have it removed, or if that is deemed the best, safest way to go, then make sure you go to a hospital that uses the DaVinci machine AND your doctor is well-versed in using it. THIS is a must. Anything less and the results will be far worse.

Some things to bear in mind -

Use of the daVinci by a skilled surgeon will reduce the incident of incontinence to almost zero.

Your chances of an abdominal (or incisional) hernia is 50/50.

Despite being in perfect health, you will NEVER go back to 'normal' in the bedroom. Ever. Don't believe that part (the doctors saying you will return to normal), because things will not be the same with you. You simply can't do what you did before.

The emotional toll for most men post-operation is larger than indicated. Remember, you will lose two of the three things that define you as a man (you can still pee standing up).

Most of all, you are not alone in this. Most doctors can refer you to previous patients for their advice and help, and you may want to do this, just so you know exactly what to expect should you decide to remove it.

Most importantly - think long term. It's better to give up a few things than to give up ALL things!
