PROSTATE CANCER

The human body is made up of trillions of cells, which are the basic building blocks of all living tissues. These cells are constantly dividing to produce new cell, a natural and essential process that supports growth, repair, and healing throughout life.

Occasionally, a cell may become abnormal. While the exact reasons for this aren't always clear, it can be due to a mix of genetic factors, environmental exposures, or random errors during cell division. When abnormal cells avoid the usual checks and balances that control cell growth, they can begin to divide uncontrollably. Over time, this unchecked growth can lead to the formation of a lump or mass known as a tumor.

Not all tumors are cancerous. A benign tumor means the abnormal growth is not cancer. It may still increase in size, but it does not invade nearby tissues or spread to other parts of the body. In contrast, a malignant tumor is cancer. Malignant tumors can grow aggressively, invade surrounding tissues, and, if left untreated, may spread to distant parts of the body through the bloodstream or lymphatic system, a process known as metastasis.

Some cancers grow and spread rapidly, while others progress more slowly. Early detection and treatment are important, as they can significantly affect the outcome.

What is Prostate Cancer?

Prostate cancer develops in the prostate gland, a small organ located just below the bladder in men. The prostate produces fluid that nourishes and transports sperm. Like many types of cancer, prostate cancer begins when cells in the prostate start growing uncontrollably.

Most prostate cancers grow slowly and may not cause serious harm. However, some types can be aggressive and spread quickly if not detected and treated early.

Why is Prostate Cancer Important in Barbados?

Prostate cancer is one of the most commonly diagnosed cancers among Barbadian men. According to the Barbados National Registry for Chronic Non-communicable Disease (BNR), prostate cancer has consistently ranked as the leading cause of cancer-related deaths in men locally.

Key factors contributing to its impact include:

High prevalence among Afro-Caribbean men, who are statistically at higher risk for developing aggressive forms of the disease.
Late presentation due to limited awareness, stigma, or fear surrounding screening and diagnosis.
Increasing life expectancy, which raises the likelihood of age-related cancers.

Local Significance:

Prostate cancer accounts for a substantial portion of oncology services in Barbados.
Early detection programs are available but underutilized, particularly among men over 50.
Community outreach and education efforts are essential to improving outcomes.

Risk Factors for Prostate Cancer

While the exact cause of prostate cancer is unknown, several risk factors increase the likelihood of developing it:

Age – Risk rises significantly after age 50.
Family history – Having a father or brother with prostate cancer doubles the risk.
Ethnicity – Men of African descent are at higher risk and more likely to develop aggressive disease.
Diet and lifestyle – High-fat diets, obesity, and sedentary habits may contribute.

Signs and Symptoms

In its early stages, prostate cancer may not cause any symptoms. As it progresses, possible signs include:

Frequent urination, especially at night
Difficulty starting or stopping urination
Weak or interrupted urine flow
Blood in the urine or semen
Pain in the hips, back, or pelvis (if the cancer has spread)

It’s important to note that these symptoms can also be caused by non-cancerous conditions like Benign Prostatic Hyperplasia (BPH). Only proper testing can confirm a diagnosis.

Screening and Diagnosis

Screening tests help detect prostate cancer early, often before symptoms appear. These include:

PSA Blood Test (Prostate-Specific Antigen): Measures levels of PSA, a protein produced by the prostate. Elevated levels may indicate cancer but can also occur in non-cancerous conditions.
A Multiparametric MRI (mpMRI) of the prostate may be recommended because your Prostate-Specific Antigen (PSA) level is higher than normal for your age. An elevated PSA does not always mean prostate cancer, it can also be caused by conditions such as prostate enlargement (BPH), inflammation, or infection. The MRI helps look closely at your prostate to identify any areas that may need further evaluation.

Radiologists use a standardized scoring system called PI-RADS (Prostate Imaging-Reporting and Data System) to describe what they see on your MRI.
The score helps your urologist decide whether a biopsy is recommended.

PI-RADS 1–2: Usually no biopsy is needed; your doctor may continue to monitor your PSA and prostate health.
PI-RADS 3: Your doctor may discuss either monitoring or proceeding with a targeted biopsy, depending on your individual risk factors.
PI-RADS 4–5: A targeted prostate biopsy is usually recommended to confirm if cancer is present.

Digital Rectal Exam (DRE): A physical exam where a doctor checks for abnormalities in the prostate.
Biopsy: If tests are suspicious, a biopsy (removal of a small tissue sample) may be performed for confirmation.

Treatment Options

Treatment depends on the stage of cancer, patient age, general health, and personal preference. Options include:

1. Active Surveillance

For slow-growing cancers in older men.
Involves regular monitoring with PSA tests, DREs, and biopsies.

2. Surgery (Prostatectomy)

Removal of the prostate gland. (Radical Prostatectomy)
Often recommended for localized cancer in otherwise healthy men.

3. Radiation Therapy

External Beam Radiation or Internal Radiation Therapy (BRACHYTHERAPY).
Often used as an alternative to surgery or in combination with other treatments.

4. Hormone Therapy

Lowers levels of male hormones (androgens) that fuel cancer growth.
Often used when cancer has spread or recurred.

5. Chemotherapy

Used in advanced stages when cancer no longer responds to hormone therapy.

6. Newer Options (in development or limited use locally):

Immunotherapy, targeted therapies, and advanced imaging are emerging treatments available in some regions and under research locally.

Living with Prostate Cancer

A diagnosis of prostate cancer is life-changing, but many men live long and healthy lives after treatment. Key elements of coping and recovery include:

Emotional support – Counseling and peer support can help manage fear and anxiety.
Lifestyle adjustments – A balanced diet, physical activity, and quitting smoking support overall health.
Regular follow-up – Ongoing monitoring is crucial to catch any recurrence early.

What Can You Do?

Know your risk. If you're over 50—or over 45 if you have a family history—speak to your doctor about screening.
Talk openly. Don't let fear or embarrassment delay testing or treatment.
Support others. Encourage friends and family members to learn more and take action.
