Prostate cancer is the most common cancer in men in the UK, with more than 52,000 new cases diagnosed every year.
Whilst many prostate cancers are slow-growing and may never cause significant harm, others are aggressive and require urgent intervention.
Understanding your personal risk factors and recognising early warning signs is essential for a timely diagnosis and a better long-term prognosis.
The prostate is a small, walnut-sized gland located just below the bladder. Its primary function is to produce the fluid that nourishes and transports sperm. As men age, the risk of developing mutations in this gland increases significantly.
Age Statistics: Around 75% of cases occur in men over the age of 65. It remains relatively uncommon in men under 50.
Most Common Type: Approximately 90% of cases are adenocarcinomas, which develop in the glandular tissue.
The “Silent” Nature: Because the prostate sits deep within the pelvis, many men develop localized cancer without experiencing a single outward symptom.
Unlike many other malignancies, a diagnosis of prostate cancer does not always mean immediate surgery or chemotherapy.
Active Surveillance: For low-risk, slow-growing tumors, doctors often recommend “Active Surveillance.” This involves regular PSA blood tests, MRIs, and physical exams to monitor the cancer without the side effects of invasive treatment.
Watchful Waiting: This is a less intensive version of monitoring, often used for older men where the goal is to manage symptoms rather than provide a curative (and potentially taxing) treatment.
While the exact cause of prostate cancer remains unknown, data shows that certain groups are at a significantly higher statistical risk.
Risk by Ethnicity
Statistics show a stark difference in risk based on racial background:
Black Men: 1 in 4 Black men (African or African-Caribbean heritage) will get prostate cancer in their lifetime. They are also more likely to be diagnosed at a younger age.
White Men: Roughly 1 in 8 white men will be diagnosed in their lifetime.
Asian Men: Approximately 1 in 13 men of Asian descent will develop the disease.
Genetic and Lifestyle Factors
Family History: Having a father or brother diagnosed doubles your risk.
Genetic Mutations: Inherited mutations in the BRCA1 or BRCA2 genes (commonly associated with breast cancer) significantly increase prostate cancer risk.
Obesity: Higher body fat levels are linked to a greater risk of “high-grade” (more aggressive) prostate cancer.
In its early stages, prostate cancer often has no symptoms. When symptoms do appear, they frequently mimic Benign Prostatic Hyperplasia (BPH)—a non-cancerous enlargement of the gland. You can read more about the differences between BPH and cancer to ease your mind.
Common signs include:
Urinary Changes: Difficulty starting urination, a weak flow, or feeling that the bladder hasn’t emptied fully.
Frequency: An urgent need to urinate, especially multiple times during the night (Nocturia).
Pain or Blood: Painful urination, painful ejaculation, or the presence of blood in the urine or semen.
Advanced Signs: Unexplained bone pain (often in the back or hips) can indicate the cancer has spread.
The Diagnostic Path
PSA Test: A blood test measuring Prostate-Specific Antigen. While a high level can indicate cancer, it can also be raised by infection or BPH. Learn more about understanding your PSA results.
DRE (Digital Rectal Exam): A quick physical exam where a doctor feels the prostate for irregularities.
MRI and Biopsy: If tests are abnormal, an MRI is usually performed, followed by a biopsy to confirm the presence of cancer cells.
Understanding the Gleason Score
The Gleason Score is the grading system used to determine how aggressive the cancer is. A higher score means the cells look less like healthy cells and are more likely to spread quickly.
Treatment Options
Radical Prostatectomy: Surgical removal of the prostate gland.
Radiotherapy: Using high-energy rays to kill cancer cells.
Hormone Therapy: Lowering testosterone levels to “starve” the cancer cells, as testosterone often fuels their growth.
Early detection results in a 5-year survival rate of over 90%. You should book a GP appointment if:
You have persistent urinary problems or blood in your urine/semen.
You are over 50: Most doctors recommend discussing the pros and cons of screening at this age.
You are over 45 and High-Risk: If you are Black or have a strong family history of the disease.
If your GP is concerned, they may refer you for a 2-week wait urgent cancer referral.
