What is monitoring?
Some prostate cancers grow slowly and may not affect life expectancy. In this case, it may be best to observe your cancer, rather than begin treatment, to avoid unnecessary treatment and side effects. The two ways of monitoring prostate cancer are active surveillance and watchful waiting. There is a small chance the cancer may grow more quickly than expected but this is unlikely. If the cancer starts to grow or you change your mind about your treatment, your doctor will discuss the available options with you.
