The radiation does not affect the back passage (rectum, blue) at all. When LDR prostate brachytherapy (seed or polymer source implantation) is carried out, an ultrasound probe is inserted into the rectum (back passage), and images from this probe are used to assess the size and shape of the prostate gland. This is done so that the doctor can ...
The location of radiation treatment is important, as radiation directed at regions of the body other than the pelvis (eg brain, chest, etc) should not prompt consideration of radiation proctopathy. [6] Endoscopy is the mainstay of diagnosis for radiation damage to the rectum, with either colonoscopy or flexible sigmoidoscopy.
Rates for impotence when comparing radiation to nerve-sparing surgery are similar. Radiation has lower rates of incontinence compared with surgery, but has higher rates of occasional mild rectal bleeding. [33] Men who have undergone external beam radiation therapy may have a slightly higher risk of later developing colon cancer and bladder ...
Body sites in which brachytherapy can be used to treat cancer. Brachytherapy is commonly used to treat cancers of the cervix, prostate, breast, and skin.
