Positive Margin Rates:
(What does this mean »)

A major indicator of whether all the Cancer in the Prostate has been removed at surgery, is whether there is a positive margin or not in the specimen of the prostate, after it has been excised from the patient.
If the margins are negative, it strongly indicates that all the cancer is likely to have been removed. If the margin is positive, it may indicate that some cancer has been left behind.

After 400 procedures Associate Professor Harewood's positive margin rates are as follows:
