Prostate cancer can develop without causing noticeable symptoms, particularly in its early stages. Some men may feel completely healthy and experience no problems with urination even when changes are taking place in the prostate.
Doctors say this is one reason men should not rely only on symptoms to judge their prostate health. Risk factors such as age and family history can be important when discussing whether screening may be appropriate.
Speaking to News9 Digital, Dr Gokulakrishnan PJ, Lead Consultant and HOD, Department of Urology, Aster Whitefield Hospital, and Dr Raghunath SK, Director and Head, Uro-Oncology and Robotic Surgery, HCG Cancer Hospital, KR Road, Bangalore, explained why prostate cancer can remain silent, which symptoms should be evaluated and how PSA testing is interpreted.
Why Prostate Cancer May Not Cause Symptoms
According to Dr Gokulakrishnan, early prostate cancer often does not produce obvious symptoms. A man may therefore feel well and have a normal urinary pattern even when cancerous changes are present.
The National Cancer Institute also notes that early-stage prostate cancer usually does not cause symptoms. As the disease progresses, some men may develop difficulty starting urination, a weak or interrupted urine stream, blood in the urine or semen, painful ejaculation, erectile problems or persistent pain in the back, hips or pelvis.
However, these symptoms do not necessarily indicate cancer. Benign conditions such as benign prostatic hyperplasia (BPH), prostate inflammation and other urinary problems can cause similar complaints.
Why Urinary Symptoms Alone Can Be Misleading
The prostate surrounds part of the urethra, so enlargement of the gland can interfere with the flow of urine. But a small cancerous growth may not block the urinary passage.
This means waiting for symptoms such as a weak urine stream before seeking medical advice may not always identify prostate cancer at an early stage. At the same time, urinary problems should not automatically be assumed to be cancer because several non-cancerous prostate conditions can produce the same symptoms.
What Does the PSA Test Show?
The prostate-specific antigen (PSA) test measures the amount of PSA in the blood. Doctors may use the test as part of prostate cancer screening or when evaluating prostate-related symptoms.
Importantly, a raised PSA level does not confirm cancer. PSA can also increase because of BPH, infection or inflammation of the prostate. There is also no single PSA value that can definitively distinguish cancer from a non-cancerous condition.
Dr Gokulakrishnan therefore stresses that PSA testing should be considered as part of an informed discussion with a healthcare professional rather than treating one test result as simply “normal” or “abnormal.”
The American Cancer Society recommends that men discuss the possible benefits, risks and uncertainties of prostate cancer screening with their healthcare provider before deciding whether to undergo testing. For men at average risk, this conversation generally begins at age 50. Men with higher risk may need to discuss screening earlier.
Family History Can Increase Prostate Cancer Risk
Age and family history are among the factors associated with a higher risk of prostate cancer. Having a father or brother who has had prostate cancer can increase risk, while the risk may be greater when several close relatives have been diagnosed, particularly at younger ages. Certain inherited genetic changes can also contribute to risk.
Dr Raghunath SK also points out that prostate cancer may remain symptom-free during its early stages. Changes such as frequent urination, difficulty passing urine or blood in the urine should be medically evaluated, but these symptoms can have several possible causes.
He emphasises that PSA results need to be interpreted in context. A high PSA can occur because of non-cancerous conditions, while prostate cancer can sometimes be present even when PSA is not markedly elevated. Screening can also detect slow-growing cancers that might never become a significant health problem.
For this reason, decisions about PSA testing and any follow-up investigations should take into account an individual’s age, family history, overall health and personal risk factors. Rather than waiting for symptoms, men can discuss their individual risk and screening options with a qualified healthcare professional.
