Experiencing changes in your urinary habits can cause immediate concern. Many men naturally worry about their prostate health as they age, especially when symptoms like frequent urination or difficulty starting a stream begin to appear. These signs often trigger fears of a serious illness.
However, prostate issues are incredibly common and do not automatically mean you have a life-threatening condition. The two most frequent culprits behind these symptoms are benign prostatic hyperplasia (BPH) and prostate cancer. While they share the same anatomical location and often present with similar warning signs, they are entirely different medical conditions.
Understanding how a benign enlarged prostate differs from a malignant tumour can help ease your mind and guide your next steps. This blog provides an overview of the definitions, clinical features, diagnostic approaches, and treatment pathways for both conditions, supporting informed decision-making.
Benign prostatic hyperplasia, commonly referred to as BPH, is a non-cancerous enlargement of the prostate gland. The prostate naturally grows as men get older. For many, this growth eventually pinches the urethra, the tube that carries urine from the bladder out of the body.
Because BPH is strictly benign, the cells do not mutate or spread to other parts of the body. It is considered a normal part of the ageing process for men. By age 60, over half of all men will have some degree of BPH, and that number jumps to 90% by age 85. While it can cause frustrating and uncomfortable urinary symptoms, BPH is not life-threatening.
Prostate cancer occurs when cells in the prostate gland mutate and multiply out of control, forming a malignant tumour. Unlike the uniform, benign growth seen in BPH, cancer cells can invade nearby tissues. If left untreated, they can spread through the bloodstream or lymphatic system to other areas of the body, such as the bones or lymph nodes.
Prostate cancer is the second most common cancer among men worldwide. Fortunately, it typically grows very slowly. Many men live for years with prostate cancer without experiencing any symptoms or needing aggressive treatment. Early detection significantly increases the chances of successful treatment and long-term survival.
The overlapping symptoms between BPH and prostate cancer cause a great deal of confusion. Both conditions affect the prostate gland's ability to function normally, which in turn impacts the urinary tract.
Because both BPH and prostate tumours can press against the urethra and bladder, they share several core symptoms
In its earliest stages, prostate cancer often causes absolutely no symptoms. It is usually only when the tumour grows large enough to compress the urethra that issues arise. However, advanced prostate cancer can present additional warning signs that are rarely associated with BPH. These include
The exact cause of BPH remains unclear, though experts believe it relates to hormone changes that happen as men age. The primary risk factors are simply age and a family history of an enlarged prostate.
Prostate cancer shares the risk factors of age and family history, but genetics plays a much stronger role. Men with a father or brother who had prostate cancer face a significantly higher risk. Race also plays a factor, as prostate cancer is more prevalent and often more aggressive in Black men. Diet, obesity, and exposure to certain chemicals may also contribute to the likelihood of developing malignant cells.
Because the symptoms are so similar, a doctor cannot diagnose BPH or prostate cancer based on your complaints alone. They rely on specific tests to determine exactly what is happening inside your body. The diagnostic process usually begins with a prostate-specific antigen (PSA) blood test and a digital rectal exam (DRE). The prostate gland produces a protein called PSA. Elevated levels can indicate BPH, an infection, or prostate cancer. During a DRE, a doctor physically checks the prostate for abnormal size, shape, or hard lumps. A smooth, uniformly enlarged prostate often points to BPH. Hard nodules or irregular shapes raise suspicions of cancer.
If cancer is suspected, the doctor will order an MRI or an ultrasound to visualise the gland. The only definitive way to diagnose prostate cancer is through a biopsy, where a specialist extracts tiny tissue samples from the prostate to examine under a microscope for malignant cells.
Treatment strategies for BPH and prostate cancer differ completely, reflecting the distinct nature of each condition.
The management of BPH focuses on relieving urinary symptoms and improving quality of life. Doctors often start with medications that relax the muscles around the prostate or shrink the gland itself. If medications fail to provide relief, minimally invasive procedures or surgeries can remove the excess prostate tissue blocking the urethra.

If medications fail to provide relief, minimally invasive procedures or surgeries, such as TURP, TUIP, HoLEP, or ThuLEP, may be recommended.
These procedures involve introducing a scope through the penile urethra, and the surgeon removes excess prostate tissue blocking the urethra.
Does having BPH increase my risk of getting prostate cancer?
No. BPH does not cause cancer, nor does it increase your chances of developing prostate cancer in the future. They are separate conditions that develop in different parts of the prostate gland.
Can a person have both BPH and prostate cancer at the same time?
Yes. Because both conditions are highly common in older men, it is entirely possible to have an enlarged prostate and prostate cancer simultaneously.
How can we diagnose prostate cancer early?
As per guidelines, it is recommended to screen for prostate cancer in all males between 55 and 70 years.
As part of the screening process, all males in this age group should get their blood PSA levels checked and a digital rectal examination done by a Urologist to help diagnose prostate cancer at an early stage.
When should I see a doctor?
You should schedule an appointment with a healthcare professional as soon as you notice any changes in your urinary habits or if you experience pain, discomfort, or blood in your urine.
Noticeable changes to your urinary routine require medical evaluation, but they do not guarantee a worst-case scenario. BPH is incredibly common and highly treatable. While prostate cancer is a serious diagnosis, early detection offers excellent outcomes.
Do not let fear delay your medical care. Regular screenings and open conversations with your doctor are your best tools for maintaining prostate health. Schedule a check-up if you are experiencing symptoms, and talk to your healthcare provider about when you should begin routine prostate screenings based on your age and risk factors.
