It makes no difference how big prostate cancer grows. The sizes of the nodules vary from small to large aggregates. Measurement of cancer spread is not the primary goal of diagnostic procedures like biopsies; finding its presence is key. Using imaging data, PSA levels, and Gleason scores allows for more comprehensive decisions concerning treatment and staging. Better results and prompt treatment depend especially on routine testing for men of 50 years of age and older. Consult medical professionals for specific guidance.
