Laser removal of rectal mass

I am 58 years old. I was diagnosed with prostate cancer three months ago. I have finally decided that I will get radiation therapy (seeds plus external IMRT beam) to treat this. I had a colonoscopy last week for a regular checkup. The doctor found a mass in my rectum. It seems to be about 9 to 10 cm from the anal verge. The biopsy showed it is benign. He said he could burn it off with a blue argon laser. My radiation oncologist said I definitely should have this done before any radiation treatments.

Is this a relatively simple procedure? My GI MD is fairly young. I thought about seeking a more experienced MD for this, if it is considered quite serious. My main question is: will this procedure cause me to be at greater risk for complications from the radiation. Complications like radiation proctitis or a rectal fistula?

How long should I wait after the laser procedure before we do the seeds and radiation?

Can there be complications from the laser procedure like damage to the rectal wall?

Any recommendations you have would be greatly appreciated.

To answer your questions:
1) The argon laser for rectal mass removal is not an uncommon approach to a mass like this.  Although possible, radiation proctitis or a fistula would be unlikely.

2) I cannot comment on when to do the procedure without examination.  This should be discussed in conjunction with your oncologist and GI physician.

3) Complications like bleeding and infection on the rectal well should be considered.

These questions should be discussed with your personal physician.

Followup with your personal physician is essential.
