There are no warning signs of early prostate cancer. Once a tumor causes the prostate gland to swell, or once cancer spreads beyond the prostate, the following symptoms may happen:
A frequent need to urinate, especially at night
Difficulty starting or stopping a stream of urine
A weak or interrupted urinary stream
Leaking of urine when laughing or coughing
Inability to urinate standing up
A painful or burning sensation during urination or ejaculation
Blood in urine or...
If PSA levels begin to rise at any time after treatment, a local or distant recurrence may be occurring, requiring additional testing.
Prostate cancer can recur locally in the tissue next to the prostate or in the seminal vesicles (two small sacs next to the prostate that store semen). The cancer may also affect the surrounding lymph nodes in the pelvis or lymph nodes outside this area.
Prostate cancer can also spread to tissues next to the prostate, such as the muscles that help control urination, the rectum, or the wall of the pelvis. It also can travel through the bloodstream and recur distantly in bones or other organs. This spread is called metastasis. Metastases through the lymph channels are called lymphatic metastases, while those through the bloodstream are hematogenous, or blood-borne metastases.
How Common Is Recurrence of Prostate Cancer?
Nearly 100% of men with low- to intermediate-grade prostate cancer ( the most common types) can expect to live at least five years after the initial diagnosis. According to the American Cancer Society, 91% of men diagnosed with prostate cancer survive at least 10 years and 76% survive 15 years. Since many men who get prostate cancer are already elderly, they are more likely to die from causes other than the cancer.
More than 90% of the time prostate cancer is discovered while it is either confined to the prostate gland or has spread beyond the prostate only to a small degree, referred to as regional spread.
Among the less than 10% of men whose prostate cancers have already spread to distant parts of the body at the time of diagnosis, about 31% are expected to survive at least five years.
How Is a Recurrence Detected?
After prostate cancer treatment, you will go for medical check-ups every few months as determined by your doctor. At each follow-up appointment, your doctor will order a blood test to measure PSA levels. This test helps your doctor detect a cancer recurrence. You will also be examined. New symptoms should be reported to the doctor, as these may prompt other testing. The PSA test is excellent, but it is not a perfect tool.
When PSA test results suggest that the cancer has come back or continued to spread, X-rays or other imaging tests (such as a bone scan) may be done, depending on your situation and symptoms.
