T1: Clinically inapparent (identified by needle biopsy (e.g., because of elevated PSA level)
T2: Tumour palpable and confined within the prostate
T3: Tumour extends through prostatic capsule but is not fixed and does not invade adjacent structures, that is, rectal mucosa is mobile over prostate
T4: Tumour is fixed or invades adjacent structures other than seminal vesicles such as rectum (rectal mucosa immobile over prostate)
