Everything You Want to Know About Prostate Cancer

Prostate cancer is a prevalent form of cancer that affects the prostate gland, a small walnut-sized organ located below the bladder in men. It is the second most common cancer among men worldwide. Prostate cancer typically develops slowly, and many men may not experience any symptoms in the early stages. However, if left untreated, it can become aggressive and potentially spread to other parts of the body. Early detection through regular screenings, such as the prostate-specific antigen (PSA) test, is crucial for successful treatment. Treatment options for prostate cancer include surgery, radiation therapy, hormone therapy, and in some cases, active surveillance. While the disease poses a significant health risk, advancements in medical research and improved awareness have contributed to better outcomes and a higher survival rate for those diagnosed with prostate cancer. It is essential for men to stay informed about their risk factors and engage in open discussions with healthcare professionals to make informed decisions about their prostate health.

Types of prostate cancer

Prostate cancer is a type of cancer that develops in the prostate, a small gland located below the bladder and in front of the rectum in men. There are several types of prostate cancer, which can be classified based on their microscopic appearance, growth patterns, and other characteristics. The most common type of prostate cancer is adenocarcinoma, but there are other less common subtypes as well. Here are some of the main types of prostate cancer:


Adenocarcinoma is the most common type of prostate cancer, accounting for more than 95% of all cases. It originates in the glandular cells of the prostate and typically grows slowly. Most prostate cancers are adenocarcinomas.

Small Cell Carcinoma

Small cell carcinoma of the prostate is a rare and aggressive form of prostate cancer. It tends to grow quickly and may have a poorer prognosis compared to adenocarcinoma.

Ductal Adenocarcinoma

Ductal adenocarcinoma is a subtype of prostate cancer that begins in the cells lining the ducts of the prostate gland. It can be more aggressive and less responsive to treatment than typical adenocarcinoma.


Prostate sarcomas are rare and develop from the connective tissues in the prostate. They can be more aggressive and difficult to treat than adenocarcinomas.

Neuroendocrine Tumors

Neuroendocrine tumors of the prostate are also uncommon and may grow more rapidly than typical adenocarcinomas. These tumors can exhibit features of neuroendocrine cells and may not respond well to hormonal therapies.

Transitional Cell Carcinoma

Transitional cell carcinoma of the prostate is extremely rare and originates in the cells lining the urethra rather than the prostate gland itself.

Prostate cancer causes and risk factors

Prostate cancer is a complex disease with multiple potential causes and risk factors. It’s important to note that while certain factors may increase the risk of developing prostate cancer, having one or more of these risk factors does not guarantee that an individual will develop the disease. Here are some of the known causes and risk factors associated with prostate cancer:


Prostate cancer is most common in older men, with the risk increasing significantly after the age of 50. The majority of prostate cancer cases are diagnosed in men over 65.

Family History

A family history of prostate cancer can increase the risk, especially if close relatives such as a father, brother, or son have had the disease. Having multiple affected relatives or a family history of early-onset prostate cancer may further elevate the risk.


Some genetic mutations and variations can increase the risk of prostate cancer. For example, mutations in the BRCA1 and BRCA2 genes, which are more commonly associated with breast and ovarian cancers, have been linked to an increased risk of prostate cancer in men.

Race and Ethnicity

Prostate cancer is more common in African-American men and less common in Asian and Hispanic men compared to white men. African-American men are not only more likely to develop prostate cancer but also tend to have a more aggressive form of the disease.

Lifestyle Factors

Certain lifestyle factors can affect the risk of prostate cancer. These include a diet high in red and processed meats, low intake of fruits and vegetables, obesity, and a sedentary lifestyle. Smoking and heavy alcohol consumption may also increase the risk.


Prostate cancer incidence rates can vary significantly by geographic location. It is more common in North America, northwestern Europe, and less common in Asia, Africa, and South America.

Hormone Levels

Prostate cancer is influenced by male hormones, particularly testosterone. High levels of testosterone or a history of hormone therapy for conditions like transgender hormone therapy may increase the risk.


Chronic inflammation of the prostate (chronic prostatitis) may be associated with an increased risk of prostate cancer, although the relationship is not fully understood.

Occupational Exposure

Some studies have suggested that occupational exposure to certain chemicals, like cadmium, may be associated with an increased risk of prostate cancer.

Prostate cancer symptoms

Prostate cancer is one of the most common cancers in men, and its symptoms can vary from person to person. In the early stages, prostate cancer may not cause any noticeable symptoms. However, as the cancer progresses, you may experience the following signs and symptoms:

  1. Urinary Symptoms:
    • Frequent Urination: You may need to urinate more often, especially at night.
    • Urgency: You may feel a strong and sudden need to urinate.
    • Difficulty Starting and Stopping Urination: Prostate cancer can affect the prostate gland, which surrounds the urethra, leading to difficulty in initiating or stopping the flow of urine.
    • Weak Urine Stream: The stream of urine may be weaker or interrupted.
  2. Blood in Urine or Semen: Some men may notice blood in their urine or semen.
  3. Pain and Discomfort: Prostate cancer can sometimes cause pain or discomfort in the pelvic area, lower back, hips, or upper thighs.
  4. Erectile Dysfunction: Difficulty achieving or maintaining an erection can be a symptom of advanced prostate cancer.
  5. Bone Pain: If the cancer has spread to the bones, it may cause bone pain, particularly in the spine, hips, and ribs.

It’s important to note that these symptoms are not exclusive to prostate cancer and can be caused by other medical conditions as well. If you experience any of these symptoms, particularly if they are persistent or severe, it is essential to consult a healthcare professional. Early detection of prostate cancer can greatly improve the chances of successful treatment.

Routine screening for prostate cancer, which typically involves a prostate-specific antigen (PSA) blood test and a digital rectal exam (DRE), can help detect the cancer in its early stages, even before symptoms appear. Your doctor can provide guidance on when and how often to undergo screening based on your individual risk factors.

Early detection of prostate cancer

Early detection of prostate cancer is crucial for improving the chances of successful treatment and better outcomes. There are several methods and tests available for prostate cancer screening:

Prostate-Specific Antigen (PSA) Test

This blood test measures the level of PSA, a protein produced by the prostate gland, in the blood. Elevated PSA levels can be a sign of prostate cancer, but they can also be elevated for non-cancerous reasons like an enlarged prostate (benign prostatic hyperplasia) or inflammation. A rising PSA level over time may indicate a potential problem.

Digital Rectal Examination (DRE)

In this physical exam, a doctor inserts a gloved, lubricated finger into the rectum to feel the prostate gland for abnormalities or irregularities. This can detect lumps or hard spots on the prostate.

Multiparametric Magnetic Resonance Imaging (mpMRI)

MRI scans can help identify suspicious areas in the prostate. If an MRI detects a lesion, it can guide further diagnostic and treatment decisions.

Prostate Biopsy

A biopsy involves taking small tissue samples from the prostate gland to determine if cancer is present. It is often recommended if there are abnormal PSA levels or suspicious findings on imaging.

Prostate Cancer Genetic Testing

Some genetic tests, like the PCA3 assay or 4Kscore, can provide additional information to help determine the risk of prostate cancer.

Risk Assessment

Your doctor may assess your risk factors, such as family history, age, and race, to determine if you should undergo screening. African American men and men with a family history of prostate cancer are at a higher risk.

Prostate cancer stages

Prostate cancer is staged to determine the extent of the disease and to help guide treatment decisions. The most commonly used staging system for prostate cancer is the TNM system, which stands for Tumor, Nodes, and Metastasis. This system categorizes prostate cancer into different stages based on the size and extent of the tumor (T), whether it has spread to nearby lymph nodes (N), and whether it has metastasized to distant organs (M). The stages are typically expressed as follows:

  1. Stage 0 (T0 or T1a): This is the earliest stage of prostate cancer, where the cancer is not detectable through physical examination or imaging, but it may be found incidentally during surgery for other reasons. It’s often referred to as latent or occult cancer.
  2. Stage I (T1b or T1c): At this stage, the cancer is small and confined to the prostate gland. It is usually discovered incidentally during surgery for other reasons.
  3. Stage II (T2): Stage II is divided into two sub-stages:
    • Stage IIA (T2a): The cancer is confined to one-half or less of one side (lobe) of the prostate.
    • Stage IIB (T2b): The cancer is present in more than half of one side (lobe) of the prostate but not both lobes.
  4. Stage III (T3): In this stage, the cancer has grown beyond the prostate and may have invaded nearby tissues or structures. It can involve the seminal vesicles.
  5. Stage IV (T4): Stage IV is divided into two sub-stages:
    • Stage IVA (T4a): The cancer has spread to nearby organs, such as the bladder or rectum.
    • Stage IVB (T4b): The cancer has spread to nearby lymph nodes or other distant organs, like the bones.

The N and M stages indicate the extent of lymph node involvement and the presence of distant metastasis, respectively:

  • N0: No regional lymph node involvement.
  • N1: Regional lymph node involvement.
  • M0: No distant metastasis.
  • M1: Distant metastasis is present.

The combination of the T, N, and M stages helps determine the overall stage of the prostate cancer. For example, someone with a T2N0M0 diagnosis has stage II prostate cancer, while someone with a T4N1M1 diagnosis has stage IV prostate cancer.

Prostate cancer treatment

Prostate cancer treatment options vary depending on the stage of the cancer, the age and overall health of the patient, and other individual factors. Common treatment modalities for prostate cancer include:

Active Surveillance

In cases of low-risk, early-stage prostate cancer, active surveillance may be recommended. This involves closely monitoring the cancer’s progression through regular PSA tests, digital rectal exams, and biopsies, with the intent of delaying or avoiding active treatment.


Surgical removal of the prostate, known as a radical prostatectomy, is a common treatment for localized prostate cancer. This can be done through open surgery, laparoscopic techniques, or robot-assisted surgery (robotic prostatectomy).

Radiation Therapy

Radiation therapy uses high-energy rays to target and kill cancer cells. It can be delivered externally (external beam radiation therapy) or internally using radioactive seeds implanted in the prostate (brachytherapy). Radiation therapy is often used for localized cancer and can also be used in combination with surgery or as the primary treatment for some cases.

Hormone Therapy

Prostate cancer is often driven by male hormones called androgens, particularly testosterone. Hormone therapy, also known as androgen deprivation therapy (ADT), is used to lower testosterone levels or block its effects. This can slow the growth of the cancer or shrink it, especially in cases where the cancer has spread beyond the prostate (advanced or metastatic prostate cancer).


Chemotherapy is typically reserved for advanced or metastatic prostate cancer that is not responding to other treatments. Chemotherapy drugs are administered intravenously and target rapidly dividing cancer cells throughout the body.

Targeted Therapies

Targeted therapies are drugs that specifically target molecules involved in the growth and spread of cancer. Some of these therapies are used in combination with hormone therapy for advanced prostate cancer.


Immunotherapy, such as sipuleucel-T (Provenge), is an option for advanced prostate cancer. It stimulates the patient’s immune system to target and attack prostate cancer cells.

Bone-Directed Treatment: For cases where prostate cancer has spread to the bones, treatments like bisphosphonates or denosumab may be used to help strengthen bones and reduce the risk of fractures or other complications.

Palliative Care: This type of care focuses on providing relief from the symptoms and side effects of cancer, rather than aiming to cure the disease. It can help improve a patient’s quality of life, especially in advanced stages of prostate cancer.

Prostate cancer prevention

Prostate cancer prevention involves adopting a combination of lifestyle choices and early detection strategies to reduce your risk of developing this disease. While there are no foolproof methods to completely prevent prostate cancer, the following steps can help lower your risk:

  1. Maintain a Healthy Diet:
    • Consume a diet rich in fruits and vegetables, particularly those high in antioxidants, such as tomatoes, broccoli, and berries.
    • Limit the intake of red and processed meats.
    • Choose healthier fats, like those found in nuts, seeds, and olive oil, and reduce saturated fats from sources like red meat and dairy.
  2. Exercise Regularly:
    • Engage in regular physical activity, such as brisk walking, jogging, or cycling, for at least 150 minutes per week.
    • Maintain a healthy weight, as obesity has been linked to an increased risk of prostate cancer.
  3. Stay Hydrated:
    • Drink plenty of water and limit your consumption of sugary drinks and excessive alcohol.
  4. Quit Smoking:
    • If you smoke, seek help to quit. Smoking is associated with an increased risk of various cancers, including prostate cancer.
  5. Limit Alcohol Consumption:
    • If you drink alcohol, do so in moderation. Excessive alcohol intake may increase your risk.
  6. Maintain a Healthy Lifestyle:
    • Manage stress through relaxation techniques, like meditation and yoga.
    • Get adequate sleep to support overall health.
  7. Regular Screenings:
    • Regular prostate cancer screenings are essential for early detection. Consult with your healthcare provider about the benefits and risks of prostate-specific antigen (PSA) tests and digital rectal exams (DRE).
    • Discuss your personal risk factors with your doctor, such as age, family history, and race, as these can impact the screening recommendations.
  8. Medications:
    • In some cases, medications like 5-alpha reductase inhibitors (finasteride and dutasteride) may be prescribed for men at high risk of prostate cancer, although the benefits and risks should be discussed with a healthcare professional.
  9. Genetic Counseling:
    • If you have a family history of prostate cancer or a known genetic predisposition, consider genetic counseling to understand your risk and explore appropriate preventive measures.

The Bottom Line

“Early detection and timely intervention remain the bottom line in the fight against prostate cancer, offering the best chance for effective treatment and improved patient outcomes.”
