 [ Symptoms ] my son is 8 months old and coughs all the time and has a hard tummy [ Disease ] hi found you this info below from <link>#tcm9 45334 there are two ways of giving brachytherapy for prostate cancer small radioactive seeds can be inserted into the tumour and left to release their radioactivity slowly this is sometimes known as low dose rate treatment the seeds are not removed and the radiation gradually fades away over about six months all the radioactivity is absorbed by the prostate so it is safe for you to be around other people as a precaution you will be advised to avoid long periods of close contact with children and pregnant women your specialist will give you more information about the precautions you should take alternatively the seeds can be placed inside special catheters that have been inserted into the prostate gland while you are asleep in an operating theatre the seeds are put into the catheters for a set period of time and are then taken out this is known as high dose rate treatment after the treatment the catheters are removed and no radioactive material is left in the prostate gland do hope this is what your looking for in the way of help good luck
