Introduction
Prostate cancer is one of the most common cancers affecting men, but here’s the crucial fact: when caught early, its treatment is highly successful. The challenge lies in its silence; early-stage prostate cancer often presents no obvious signs. This makes understanding the nuances of early detection not just helpful, but potentially life-saving. This guide demystifies prostate cancer symptoms, breaks down the screening debate, and empowers you with knowledge. Whether you're assessing your own risk or supporting a loved one, we’ll walk you through everything from subtle urinary changes to understanding PSA tests, helping you build a proactive plan for your health. Knowledge is your first and best defense.
Know the Signs: Symptoms of Prostate Cancer
Understanding the symptoms of prostate cancer is tricky because the disease exists on a spectrum. Early-stage cancer, confined to the prostate gland, may cause no symptoms at all. This is why screening is so vital for high-risk groups. Symptoms typically appear when the cancer grows large enough to press against the urethra or, in more advanced cases, spreads to other parts of the body.
It's also critical to distinguish between cancer and a very common, non-cancerous condition called Benign Prostatic Hyperplasia (BPH), which shares many of the same urinary symptoms. Not every urinary change signals cancer, but any persistent change warrants a doctor's attention.

Later-Stage and Advanced Symptoms
When the disease progresses, symptoms become more pronounced and can be divided into two categories.
Urinary Changes You Shouldn't Ignore
It includes:
1. These occur due to the enlarged prostate pressing on the bladder and urethra.
2. Frequent urination, especially at night (nocturia).
3. A weak or interrupted urine stream.
4. Difficulty starting or stopping urination.
5. A sense of not fully emptying the bladder.
6. Pain or a burning sensation during urination (dysuria).
7. Blood in the urine (hematuria) or semen.
Beyond the Bathroom: Systemic Symptoms
It includes:
1. These symptoms suggest the cancer may have spread (metastasized), most commonly to the bones.
2. Pain in the back, hips, pelvis, or thighs that doesn't go away.
3. Unexplained weight loss.
4. Erectile dysfunction.
Unique Insight: Many men dismiss back pain as a simple ache of ageing. However, prostate cancer-related bone pain is often a deep, persistent ache that doesn’t improve with rest or standard pain relievers and may be worse at night. This distinction is important for early detection of advanced disease.
The Prostate Cancer Screening Toolkit
Screening is the process of looking for cancer before a person has any symptoms. For prostate cancer, the toolkit has two primary first-line tools, with others available for clarification.
The Prostate-Specific Antigen (PSA) Blood Test
This is the cornerstone of screening. The PSA test measures the level of PSA, a protein produced by both cancerous and non-cancerous prostate tissue, in your blood.
• How it works: A small blood sample is drawn and analysed.
• The nuance: An elevated PSA level does not automatically mean cancer. It can be raised by BPH, prostatitis (inflammation), recent ejaculation, or even a long bike ride. This is the source of the test's controversy—it can lead to false alarms and unnecessary biopsies.
Understanding Your PSA Results
There is no single "normal" PSA level. Doctors interpret results based on:
1. Age: PSA naturally creeps up with age.
2. Velocity: How quickly the PSA level rises over time.
3. Density: PSA level in relation to the size of the prostate.
4. A result between 4 and 10 ng/mL is considered suspicious, and results above 10 ng/mL are even more so. However, a man with a large prostate might have a PSA of 5.5 and be fine, while a man with a PSA of 3.0 could have cancer if his level jumped from 1.0 the year before.
The Digital Rectal Exam (DRE)
This is a physical examination where a doctor inserts a gloved, lubricated finger into the rectum to feel the prostate gland.
1. Purpose: To check for abnormalities in the gland's size, shape, or texture, such as hard areas or lumps.
2. Limitation: The doctor can only feel the back of the prostate. Cancers can develop in areas unreachable by a finger.
The PSA test and DRE are complementary. One can be abnormal while the other is normal. If either test is suspicious, it triggers the next step in the diagnostic pathway.
If you receive an elevated PSA test result, don't panic. The next step is often a conversation with a urologist about advanced biomarker tests like the 4Kscore or PHI test, which can better assess the probability of aggressive cancer and help avoid an unnecessary biopsy.
Making an Informed Decision: To Screen or Not to Screen?
This is the most critical conversation to have with your doctor. Major health organisations disagree on screening guidelines for average-risk men due to the risks of overdiagnosis, finding slow-growing cancers that would never have caused harm, and overtreatment, which can lead to side effects like incontinence and erectile dysfunction.
The consensus is:
1. Age 50: for men at average risk.
2. Age 45: for men at high risk (e.g., African American men or those with a father or brother diagnosed with prostate cancer before age 65).
3. Age 40: for men at even higher risk (e.g., those with more than one first-degree relative who had prostate cancer at an early age).
The decision should be shared. Discuss your personal risk factors, your values regarding potential side effects, and your tolerance for uncertainty with your doctor. If you are experiencing any persistent symptoms or have a strong family history, consulting a doctor online with Apollo24|7 can be a convenient first step to discuss your risk and whether screening is right for you.
Conclusion
Navigating the path of prostate health can seem complex, but awareness is your most powerful tool. Understanding the often-subtle symptoms and the pros and cons of early detection methods like the PSA test empowers you to have informed, productive conversations with your healthcare provider. Remember, prostate cancer, when caught in its initial stages, is highly treatable. Proactivity is key. Know your personal risk factors, listen to your body, and don't hesitate to seek medical advice for any persistent changes. Your health is worth the conversation.

Frequently Asked Questions
1. What is the most common first sign of prostate cancer?
For many men, there is no first sign, which is why screening is important. When symptoms do appear, the most common early signs are changes in urinary function, such as needing to urinate more frequently, especially at night, or a weaker urine stream.
2. At what age should you start getting screened for prostate cancer?
Most guidelines recommend starting the conversation with your doctor at age 50 for average-risk men. However, if you are African American or have a father or brother who had prostate cancer, you should start this discussion at age 45.
3. Can you have prostate cancer with a normal PSA level?
Yes, it is possible. This is called a false negative. While less common, some aggressive forms of prostate cancer may not produce high levels of PSA. This is why the digital rectal exam (DRE) is sometimes used alongside the PSA test for a more comprehensive assessment.
4. What are the main causes of an elevated PSA level?
An elevated PSA level is most commonly caused by Benign Prostatic Hyperplasia (BPH—an enlarged prostate) or prostatitis (inflammation of the prostate). Recent activities like ejaculation, a bike ride, or even a urinary catheter placement can also temporarily raise PSA. Cancer is one potential cause, but not the most common.
5. What is a suspicious PSA level?
While 4.0 ng/mL was traditionally the cutoff, it's more nuanced now. A level above 4.0 is generally considered elevated, but doctors also look at PSA velocity (how fast it rises) and density (PSA relative to prostate size). A jump from 2.0 to 3.5 in a year may be more suspicious than a stable level of 4.5 in a man with a known large prostate.
