Hi there. I have done some reading up on PSA readings and how reliable they are / how they can be interpreted etc.
So I know for instance that because my brother has just recorded a PSA reading of 15 doesn't mean he has prostate cancer.
But he has had some urinary problems, and he has just gone googling and found some source that says readings >10 mean that there is a 50% chance of there being cancer present. Is this correct?
Other than that, he is concerned that his GP is not very pro-active. GP has told him to submit a urine sample and to have another blood test in 3 weeks' time. Presumably to re-check PSA level?
Is that a reasonable course of diagnostic action given my brother's situation, or should there be something else going on?
Thank you.
