People talk about risk in different ways. If you've only had a psa test and not a DRE or MRI then under 10 will be lower risk of actual cancer. 10 to 20 medium risk and over 20 higher risk and higher risk of spread.
PSA by itself is very unreliable. It can be inflammation in many cases, even up to psa 400.
After more tests psa still has the same boundaries but it is used to categorise whether you should get treated as low risk or slow growing or high risk faster growing
So it gets more complicated see below for one way to look at it. There are other ways.
Note the below is American. It was the best my first search showed and I've cut bits out.
Your prostate cancer doctors will use your test results to determine your risk group, which is a way categorizing the overall severity of a case and applying evidence and experience to inform your treatment options. There are 3 general risk groups
- Low risk: Tumor is confined to the prostate, and the PSA is <10 and grade group 1 (Gleason 6).
- Intermediate risk: Tumor is confined to the prostate, the PSA is between 10 and 20, or grade group 2 or 3 (Gleason 7). This category is often divided into a “favorable” and “unfavorable” intermediate risk.
- High risk: Tumor extends outside the prostate, the PSA >20, or grade group 4 or 5 (Gleason 8 to 10). There is also a subset of very aggressive tumors is called “very high risk” in which the tumor has extended into the seminal vesicles (T3b) or the rectum or bladder (T4), or there are multiple biopsy samples with high grade cancer.
These risk groups are not perfect indicators.
