Kidney prostate cancer symptoms: what to know

Prostate cancer can have no noticeable symptoms in its early stages. Symptoms that do occur can overlap with non-cancerous prostate conditions, so a symptom alone cannot identify its cause.

A prostate tumour may narrow the tube that carries urine from the bladder, leading to a weak or interrupted stream, difficulty starting, needing to pass urine often, or feeling that the bladder has not emptied. Difficulty passing urine can also result from an enlarged prostate or infection.

Some people notice blood in the urine or semen, discomfort during ejaculation, or difficulty getting or keeping an erection. These changes have several possible explanations and should be assessed rather than self-diagnosed.

When prostate cancer has spread beyond the prostate, persistent pain in the back, hips, pelvis, or other bones, leg weakness, or unexplained weight loss may occur. Kidney cancer has a different symptom pattern, so blood in urine or ongoing pain near the kidney area deserves its own medical evaluation.

Arrange an appointment with a doctor if urinary, sexual, or pain-related changes persist, recur, or interfere with daily life. The assessment may include questions about timing and severity, an examination, urine testing, and blood testing; further tests are chosen according to the findings.

Write down when the change began, whether it is getting worse, any medicines you take, and whether close relatives have had prostate cancer. Do not stop prescribed medicines or assume that a urinary symptom is cancer. If prostate cancer is diagnosed, treatment choices can include monitoring, surgery, or forms of radiotherapy, depending on the tumour and your overall health.

Seek urgent medical help if you cannot pass urine, have heavy or persistent blood in the urine, develop severe worsening pain, or feel faint or very unwell. New leg weakness, numbness around the groin, or loss of bladder or bowel control with back pain needs emergency assessment because pressure on nerves can cause lasting harm.

A sudden fever with painful urination, shaking chills, or pain in the side or back may indicate an infection that needs prompt treatment. These warning signs are based on the symptom itself, not on the likelihood that it represents cancer.

You could ask: What other conditions might explain these symptoms? Which tests are appropriate for me? What would make you refer me to a specialist? If cancer is found, where is it located and what treatment choices fit my situation? How could treatment affect urination, erections, bowel function, or fertility?
