Causes & Risk Factors
Several factors can contribute to Prostate Cancer.
The exact cause of prostate cancer remains unclear, but scientists understand it begins when cells in the prostate develop changes in their DNA.
The exact cause of prostate cancer remains unclear, but scientists understand it begins when cells in the prostate develop changes in their DNA. Think of DNA as the instruction manual that tells cells how to grow, divide, and die at the right time. When these instructions get scrambled, cells can start growing out of control and living longer than they should.
These abnormal cells accumulate and form a tumor that can grow to invade nearby tissue.
These abnormal cells accumulate and form a tumor that can grow to invade nearby tissue. Over time, some of these cancer cells can break away and spread to other parts of the body, particularly bones and lymph nodes. This process, called metastasis, usually happens slowly with prostate cancer compared to other types of cancer.
Researchers believe multiple factors work together to trigger these DNA changes.
Researchers believe multiple factors work together to trigger these DNA changes. Hormones, particularly testosterone and other male hormones called androgens, seem to fuel prostate cancer growth. This explains why the disease primarily affects older men, when hormone exposure has been longest. Environmental factors, genetic predisposition, and lifestyle choices may all contribute to the complex puzzle of why some men develop prostate cancer while others don't.
Risk Factors
- Age over 50 years
- African American ethnicity
- Family history of prostate cancer
- Family history of breast or ovarian cancer
- Inherited gene mutations (BRCA1, BRCA2, Lynch syndrome)
- Diet high in red meat and high-fat dairy
- Obesity
- Tall stature
- Smoking
- Chemical exposure (Agent Orange, cadmium)
Diagnosis
How healthcare professionals diagnose Prostate Cancer:
- 1
When you visit your doctor with concerns about prostate cancer or for routine screening, the process typically begins with a conversation about your symptoms, family history, and overall health.
When you visit your doctor with concerns about prostate cancer or for routine screening, the process typically begins with a conversation about your symptoms, family history, and overall health. Your doctor will likely perform a digital rectal exam (DRE), where they gently insert a gloved, lubricated finger into your rectum to feel the prostate for any unusual lumps, hard areas, or other abnormalities. While this might feel uncomfortable, it takes less than a minute and provides valuable information.

Blood tests measure your prostate-specific antigen (PSA) level.
Blood tests measure your prostate-specific antigen (PSA) level. PSA is a protein produced by both normal and malignant cells in your prostate. Higher levels can indicate cancer, but they can also result from benign conditions like enlarged prostate or prostate infection. Your doctor will consider your age, overall health, and how PSA levels change over time rather than relying on a single number. Other blood tests might include: - Free PSA ratio - 4Kscore test - Prostate Health Index (PHI) - Genomic tests for men with family history

If initial tests raise concerns, your doctor may recommend imaging studies like multiparametric MRI to get detailed pictures of your prostate.
If initial tests raise concerns, your doctor may recommend imaging studies like multiparametric MRI to get detailed pictures of your prostate. The definitive diagnosis comes from a prostate biopsy, where a specialist removes small tissue samples using ultrasound guidance. These samples go to a pathologist who examines them under a microscope. If cancer is present, the pathologist assigns a Gleason score that helps determine how aggressive the cancer appears and guides treatment decisions.
Complications
- Most men with prostate cancer, especially when caught early, live normal lifespans without serious complications from the disease itself.
- However, both the cancer and its treatments can cause side effects that affect quality of life.
- The most common treatment-related complications involve urinary and sexual function, though these often improve over time with proper management and rehabilitation.
- Urinary problems can include temporary or permanent incontinence, ranging from occasional leaking to more significant control issues.
- Most men regain good urinary control within a year after surgery, and various treatments can help, including pelvic floor exercises, medications, and surgical procedures if needed.
- Sexual side effects, particularly erectile dysfunction, affect many men after prostate cancer treatment.
- Modern nerve-sparing surgical techniques and improved radiation methods have reduced these problems, and effective treatments include medications, devices, and counseling.
- Fertility can also be affected, so men wanting children should discuss sperm banking before treatment.
- When prostate cancer spreads beyond the prostate, bone complications become a concern since bones are the most common site of metastasis.
- Bone metastases can cause pain, fractures, and elevated calcium levels.
- Fortunately, medications called bisphosphonates and denosumab can strengthen bones and reduce these complications.
- Advanced prostate cancer may also cause fatigue, weight loss, and anemia, but modern treatments have significantly improved outcomes even for men with metastatic disease.
Prevention
- While you can't completely prevent prostate cancer, research suggests several lifestyle choices may reduce your risk or help detect it early when treatment is most effective.
- Regular screening discussions with your healthcare provider starting around age 50 (or earlier if you have risk factors) give you the best chance of catching cancer while it's still highly treatable.
- Diet appears to play a meaningful role in prostate health.
- Consider these evidence-based dietary approaches: - Eat more tomatoes, which contain lycopene, a powerful antioxidant - Include fatty fish rich in omega-3 fatty acids twice weekly - Choose more fruits and vegetables, especially cruciferous vegetables like broccoli - Limit red meat and high-fat dairy products - Reduce processed and charred meats - Maintain a healthy weight through portion control and regular physical activity Staying physically active benefits your prostate and overall health.
- Aim for at least 150 minutes of moderate exercise weekly, such as brisk walking, swimming, or cycling.
- Some studies suggest vigorous exercise may be particularly protective.
- Avoid smoking and limit alcohol consumption, as both may increase cancer risk.
- While supplements like selenium and vitamin E were once thought to be protective, large studies showed they don't prevent prostate cancer and may even cause harm in some men.
Treatment for prostate cancer has evolved dramatically over the past decade, with options tailored to your specific situation, age, overall health, and personal preferences.
Treatment for prostate cancer has evolved dramatically over the past decade, with options tailored to your specific situation, age, overall health, and personal preferences. For many men with slow-growing, low-risk cancer, active surveillance (also called watchful waiting) may be the best approach. This means regular monitoring with PSA tests, digital rectal exams, and periodic biopsies rather than immediate treatment. Many men live full, normal lives this way without ever needing aggressive treatment.
When treatment becomes necessary, surgery and radiation therapy remain the primary options for cancer confined to the prostate.
When treatment becomes necessary, surgery and radiation therapy remain the primary options for cancer confined to the prostate. Radical prostatectomy involves removing the entire prostate gland and some surrounding tissue. Modern techniques include: - Robot-assisted laparoscopic surgery - Open retropubic surgery - Perineal approach surgery. Radiation therapy can be delivered externally using precise beams targeted at the cancer, or internally through radioactive seed implants (brachytherapy). Both approaches have excellent success rates for localized cancer.
For men with advanced or metastatic prostate cancer, hormone therapy (androgen deprivation therapy) can be highly effective since prostate cancer cells often depend on male hormones to grow.
For men with advanced or metastatic prostate cancer, hormone therapy (androgen deprivation therapy) can be highly effective since prostate cancer cells often depend on male hormones to grow. This treatment can involve medications that block hormone production or prevent hormones from reaching cancer cells. Newer treatments include: - Chemotherapy with docetaxel or cabazitaxel - Immunotherapy with sipuleucel-T - Targeted therapies like enzalutamide and abiraterone - Radium-223 for bone metastases
Exciting developments include precision medicine approaches that analyze your tumor's genetic makeup to select the most effective treatments.
Exciting developments include precision medicine approaches that analyze your tumor's genetic makeup to select the most effective treatments. PARP inhibitors show promise for men with specific genetic mutations, while combination therapies are extending lives and improving quality of life. Clinical trials continue investigating new immunotherapies and targeted drugs that could transform prostate cancer from a potentially fatal disease into a manageable chronic condition.
Living With Prostate Cancer
Living with prostate cancer often means adjusting to a new normal, but most men continue enjoying active, fulfilling lives. The key lies in building a strong support team that includes your oncologist, primary care doctor, and specialists who can address treatment side effects. Many men benefit from working with a urologist who specializes in post-treatment care, helping optimize both urinary and sexual function recovery.
