Lifestyle, family could predict prostate risk
By Lee I-chia / Staff reporter
Having a prostate-specific antigen (PSA) test result above 4.0 ng/mL is considered abnormal and it is worth closer testing, a physician said yesterday, as he suggested individuals with a family history of prostate cancer begin regular screening from an earlier age.A 42-year-old man, surnamed Chen (陳), was tested with a PSA level of 5.4 ng/mL more than a year ago, but he did not experience any discomfort, while other tests, including a digital rectal examination, showed no signs of prostate inflammation, but a ultrasound showed a mildly enlarged prostate with a small nodule of about 7.9mm, Shu Tien Clinic Department of Urology director Chou Ku (周固) said.In a follow-up visit, Chen’s PSA level was tested to be even higher at 5.57 ng/mL and his free PSA level was 13 percent, so the doctor suggested he get a biopsy to investigate the condition, but he refused, Chou said.

Chen was again tested with a higher PSA level of 5.29ng/mL in the next follow-up visit, and he agreed to get a biopsy, confirming it was prostate cancer, Chou said, adding that he was referred to a larger hospital for radical prostatectomy and radiation therapy.Prostate cancer is generally found in men aged 65 or older, while the incidence rate for men aged 40 to 44 is approximately two to five per 100,000 men and lower than one per 100,000 in men aged younger than 40, he said.
However, men with a family history or lifestyle risk factors, including smoking or high consumption of alcohol or processed meat, risk of developing the disease at a younger age, he added.“Prostate cancer in younger men tends to be more aggressive, faster-growing and poses a higher risk of spreading [metastasis],” Chou said Younger people have more remaining life expectancy, so active treatment is recommended, he added. Chou said most early-stage prostate cancers do not have any symptoms and when they do, they often share similar symptoms with benign prostatic hyperplasia (BPH, noncancerous prostate enlargement), such as frequent urination (particularly at night) or weak urine flow.Tested with a high level of PSA does not necessarily indicate the presence of prostate cancer, as benign conditions such as BPH, inflammation, infection or sexual activity might affect PSA levels, so getting examinations for confirmation is recommended, he said.Meanwhile, men with a family history — particularly if a first-degree relative (father or brother) has had the disease — are recommended to start getting PSA tests regularly from 10 years before the age that their family member was diagnosed with it and avoid lifestyle risk factors to better prevent prostate cancer, Chou said.
