Low PSA Level Is Not A Guarantee Against Prostate Cancer

Low PSA Level Is Not A Guarantee Against Prostate Cancer
May be you had a normal PSA level during last years annual check up. This normal PSA level is a reassurance to all us about safety from prostate cancer.

A PSA value of less than 4 is generally considered to be a safe level. A new research from Louisiana State University Health Sciences Center in Shreveport suggests that a PSA level of less than 4 does not guarantee complete safety from prostate cancer.

Lead investigators Dr. Caleb B. Bozeman and his colleagues identified 916 patients with abnormal rectal examination findings and a PSA level lower than 4. Most of these patients underwent biopsy to see if they have prostate cancer. Researchers were surprised to find that 81 of these men had prostate cancer.

The investigators are urging combined use of rectal examination and PSA testing while screening for prostate cancer. Obviously as per the study many patients with normal PSA levels may not be diagnosed if PSA testing only is done.

The investigators also found that 1.8 percent of those who had PSA levels between 0 and 0.9 had prostate cancer highlighting the fact that no level of PSA is an absolute guarantee against prostate cancer.

Age was also a significant predictor, with cancer diagnosed among 5.4 percent of those younger than 50 years and among 11.3 percent older than 70 years.

Prostate cancer
The prostate is located just below the bladder and in front of the rectum in male. The tube that carries urine runs through the prostate. The prostate contains cells that make some of the seminal fluid. This fluid protects and nourishes the sperm. Prostate cancer usually starts in the gland cells of the prostate. This kind of cancer is known as adenocarcinoma. Prostate cancer is usually a slow disease, but sometimes it can grow fast and spread quickly to other organs.
