The most effective way of detecting the early signs of prostate cancer is a combination of a PSA blood test and a prostate ultrasound.
An abnormally high level of PSA in the blood is an indicator of possible prostate cancer although it is not definitive. High PSA levels can also indicate other prostate diseases such as benign prostatic hypertrophy or prostatitis (inflamed prostate).
The ultrasound examination is important in determining whether there is any enlargement of the prostate, or any abnormal nodules present. Larger tumours can often also be felt by a rectal examination by a urologist.
Do I need to prepare for the ultrasound?
As only a few millimetres of tissue separate the rectum and the prostate, this examination is best performed transrectally for accuracy and sensitivity of any findings. Pictures are acquired using a transrectal probe which is smooth and approximately the size of an index finger.
You will need to ensure that you have had a bowel motion beforehand so that your rectum area is empty when you come for your appointment.
