The early stages of prostate cancer are usually asymptomatic (ie, asymptomatic) and may be detected in some cases during urethral surgery for other reasons. In locally advanced tumors (those that are already spreading to the environment - into the bladder, into the urethra, but have not yet metastasized to distant organs), the main symptoms of patients are various difficulty urinating. Patients go to the toilet at shorter intervals and also more often at night, or they may retain their urine and urination is difficult for them. It is quite rare for blood to appear in the urine and for kidney disease (kidney failure or kidney failure). Pain from the bone metastatic process, especially the back, hips and limbs, is most often a sign of very advanced tumors. Bone metastasis can sometimes oppress the spinal cord and cause movement problems. Prostate tumors can differ histologically, some grow very slowly and do not metastasize, so they may have a fairly good prognosis, although they cause local urinary problems, for example.
