The use of prostate-specific antigen (PSA) for early detection of prostate cancer (PCa) 60-69 years: ≥2.25 ng/mL, ≥70 years: ≥3.25 ng/mL), together with percentage-free PSA levels of
Prostate cancer can recur locally in the pelvis or elsewhere in the body. The location of the recurrence is determined by these radiographic scans. After surgery, PSA levels should drop to zero. When PSA levels rise above 0.2 ng/mL, the cancer is considered recurrent. After treatment with radiation, PSA levels rarely drops completely to zero.
Prostate cancer metastasis may be suspected if you have specific symptoms such as new lower back pain or elevated liver enzymes. These may be signs your cancer has spread to your spine or your liver, respectively. If your prostate-specific antigen (PSA) levels continue to rise despite treatment, especially if they are rising particularly fast

Eur Urol 2005; 48: 386; Lee R, Localio AR, Armstrong K et al: A meta-analysis of the performance characteristics of the free prostate-specific
Background: Prostate-specific antigen (PSA) secretion is a testosterone (T) dependent process. Published data suggest that a low T level is an independent predictor of higher-grade prostate cancer (PC). Aim: To evaluate the relationship between T and PSA in patients with PC. Methods: All men diagnosed with PC with a recorded pre-treatment total T level measurement were included in this analysis. Serum prostate-specific antigen (PSA) has been widely used for the detection and monitoring of prostate cancer (PCa) (1,2), since the end of 1980s ().After the identification of PSA in 1979 (), several immunoassays for its quantification in serum have been developed ().Currently available commercial assays for the measurement of total PSA (tPSA) and free PSA (fPSA) are based on the
Background: The free-to-total prostate-specific antigen ratio is the best marker for optimizing prostate cancer detection. The main problem with studies of percent free PSA is the variability of reported cutoff values. Objectives: To evaluate the influence of prostate size on the ratio of free to total PSA. Methods: The study group included 58 patients (mean age 66.4 years) with clinically
If your PSA test result is in the borderline range (between 4 and 10), the percent-free PSA might be used to help decide if you should have a prostate biopsy. A lower percent-free PSA means that your chance of having prostate cancer is higher and you should probably have a biopsy.
There are several types of PSA tests that the doctor may order. Sometimes a percent-free PSA test is performed to help guide the doctor on whether or not a prostate biopsy is needed. This is because men with lower amounts of free PSA floating in the blood are more likely to have prostate cancer.

10 food and drinks to avoid that can raise your PSA level. 1. Wheat bread. Bread dietary intake may increase your PSA level in the very short term. A study performed on patients with prostate cancer divided them into three groups. One of them consumed wheat bread. The other two consumed soy and linseed-based bread.

There are concerns about a PSA test's real ability to detect prostate cancer. About 3 out of 4 men with high PSA will not have cancer and about 1 in 7 prostate cancers can be missed. Most men with high PSA tests will undergo a biopsy, which is a painful and invasive procedure. There are also concerns that many prostate cancers detected by PSA

Saka T, Sofikerim M, Demirtas A, Kulaksizoglu S, Caniklioglu M, et al. (2009) Rigorous bicycling does not increase serum levels of total and free prostate-specific antigen (PSA), the free/total PSA ratio, gonadotropin levels, or uroflowmetric parameters. Urology 74: 1325-1330. [Google Scholar]

High PSA levels can be a sign of prostate cancer. One study suggests that people who consume or have consumed alcohol have lower PSA levels, but more research is necessary to confirm these findings.

Doctors usually detect prostate cancer by measuring prostate-specific antigen (PSA) levels in your blood. After successful treatment, PSA levels tend to drop significantly. If PSA levels suddenly
