Watchful waiting, also called expectant therapy, is sometimes recommended for men who have an early stage
and no symptoms, or are elderly or sick with other medical problems.
The theory behind watchful waiting is that some prostate cancers grow very slowly and may never develop into a symptomatic or life-threatening stage of cancer. For such a slow-growing cancer, the risks and side effects of the other possible treatments for prostate cancer (such as chemotherapy,
radiation therapy) may not seem worthwhile as compared with the low-risk of the growth of prostate cancer.
However, no one knows for sure which prostate cancers are likely to grow quickly and which may grow slowly. After careful discussion with your doctor, you may choose watchful waiting. You will still receive close follow-up for any change in your condition.
