Prostate cancer has been one of the most common male cancers in Hong Kong in the past two decades, according to government statistics. In 2014, the Hong Kong Centre for Health Protection said prostate cancer accounted for more than 11 percent of all new cancer cases in men.
Many times, early symptoms of the disease go undetected, says Dr. Michael Blute of the Massachusetts General Hospital (MGH). Blute, who serves as chief of urology at MGH, offers information on prostate cancer.
Q. What are the warning symptoms of prostate cancer? Do these symptoms differ from other prostate health concerns?
A. Unfortunately, prostate cancer is truly the definition of a “silent killer”. To detect prostate cancer in its curative stage, men must regularly undergo an exam that includes a blood test for serum prostate specific antigen and a digital rectal exam by their physician.
Q. Are there symptoms that men should be aware of? If a person has these symptoms, how should they go about getting help?
A. Prostate symptoms are commonly caused by an enlarged but benign gland. However, because of cancer concern, these symptoms rightly generate requests for further evaluation. Problems with urination in men as they age are common but can be associated with prostate cancer.
Prevalence of the disease increases in the older population. In fact, about six cases in 10 are diagnosed in men aged 65 or older, and it is rarely diagnosed before age 40. If you are experiencing frequent urination, difficulty starting the stream, slowing or difficulty emptying, awakening at night and most importantly, noticing blood in the urine, you should call your doctor and have a physical for further evaluation.
Q. Who is at risk?
A. Those who have a strong family history of prostate cancer – a father, grandfather, uncle or brother – are at increased risk of developing prostate cancer.
Some studies have suggested that men with a history of breast cancer or colorectal cancer on their maternal side have increased risk for prostate malignancy. Family history of BRCA1 or BRCA2 genetic mutations has been identified as an inherited risk factor for prostate cancer. It also appears African-American men are at increased risk of developing the disease.
Q. How does a patient get screened for prostate problems?
A. First, speak with your doctor about any symptoms you are experiencing. Those symptoms, combined with your family history, will determine your physician’s next steps. In 2012, the US Preventive Services Task Force advised against routine prostate screening.
However, a more recent analysis of PSA screening supports decreased rates of developing metastatic cancer, so baseline testing of PSA and screening based on risk factors is recommended. Patients should have an open discussion of the pros and cons of screening with their physician as part of their overall health care.
Q. What is the best treatment for these men’s health issues? Are there any new therapies on the horizon for patients?
A. Again, talk to your physician. There are different courses of treatment for prostate cancer compared to other prostate issues.
For individuals with early-stage cancer, active surveillance, surgery and radiation are options for treatment. Advances in research, particularly in imaging and biomarkers, are enhancing clinicians’ ability to better detect advanced cancers that need more aggressive treatment.
This also allows for increased active surveillance of cancers that appear to carry a low burden of risk for men in terms of their health or quality of life. Medical, minimally invasive and traditional surgical options exist for managing voiding problems due to enlarged benign prostate glands.
