What is Prostate Cancer? Symptoms, Causes, & Treatment

Prostate cancer develops when cells in the prostate gland begin growing uncontrollably. The prostate is a small, walnut-sized gland that sits below your bladder and produces fluid that helps nourish and transport sperm.

This type of cancer is one of the most common cancers affecting men, especially those over 50. The good news is that most prostate cancers grow slowly and remain confined to the prostate gland, where they may not cause serious harm. Many men live full, healthy lives even after a prostate cancer diagnosis.

What are the symptoms of prostate cancer?

Early prostate cancer often causes no symptoms at all. This is why regular screening becomes so important as you age. When symptoms do appear, they usually develop gradually over time.

Here are the symptoms you might notice, keeping in mind that many of these can also be caused by non-cancerous prostate conditions:

• Difficulty starting urination or weak urine flow
• Frequent urination, especially at night
• Feeling like your bladder doesn't empty completely
• Pain or burning during urination
• Blood in urine or semen
• Painful ejaculation
• Persistent pain in your back, hips, or pelvis

These symptoms can be concerning, but remember that they're more commonly caused by benign prostate enlargement than cancer. However, any persistent changes in your urinary or sexual function deserve a conversation with your doctor.

In rare cases where cancer has spread beyond the prostate, you might experience bone pain, unexplained weight loss, or fatigue. Advanced prostate cancer can also cause leg swelling or weakness in the legs if it affects nearby lymph nodes or nerves.

What are the types of prostate cancer?

Nearly all prostate cancers are adenocarcinomas, which start in the gland cells that make prostate fluid. This is the type doctors are most familiar with treating, and it responds well to many different therapies.

Other rare types include small cell carcinomas, neuroendocrine tumors, and sarcomas. These make up less than 5% of all prostate cancers. While these rare forms can be more aggressive, they're also much less common, so most men diagnosed with prostate cancer will have the more treatable adenocarcinoma type.

Your doctor will also classify your cancer by how quickly it's likely to grow. Some prostate cancers are very slow-growing and may never cause problems, while others are more aggressive and need prompt treatment.

What causes prostate cancer?

The exact cause of prostate cancer isn't fully understood, but it develops when DNA changes cause prostate cells to grow and divide more rapidly than normal. These abnormal cells continue living when other cells would die, forming a tumor.

Several factors can increase your risk, though having risk factors doesn't mean you'll definitely develop cancer:

• Age - your risk increases significantly after 50
• Family history of prostate or breast cancer
• Race - African American men have higher risk
• Inherited gene changes like BRCA1 or BRCA2 mutations
• Geography - more common in North America and Europe

Some research suggests that diet high in red meat and high-fat dairy products might increase risk, while diets rich in fruits and vegetables may be protective. However, the evidence isn't strong enough to make definitive dietary recommendations for prevention.

It's important to understand that most men who develop prostate cancer have no controllable risk factors. This isn't something you caused or could have prevented through lifestyle choices alone.

When to see a doctor for prostate cancer?

You should talk to your doctor about prostate cancer screening starting at age 50 if you're at average risk. If you're African American or have a family history of prostate cancer, consider starting this conversation at age 45.

Don't wait for symptoms to appear before discussing screening. Remember, early prostate cancer rarely causes noticeable symptoms, which is exactly why regular check-ups become so valuable.

Schedule an appointment sooner if you experience any urinary changes like difficulty starting or stopping urination, weak flow, or frequent nighttime urination. While these symptoms are often caused by benign conditions, they warrant evaluation.

Seek prompt medical attention if you notice blood in your urine or semen, persistent bone pain, or unexplained weight loss. These symptoms, while less common, need immediate evaluation to determine their cause.

What are the risk factors for prostate cancer?

Understanding your risk factors can help you make informed decisions about screening and lifestyle choices. Some factors you can't control, while others you might be able to influence.

The risk factors you cannot change include:

• Age - risk doubles every 10 years after age 50
• Race - African American men have 60% higher risk
• Family history - risk doubles if father or brother had prostate cancer
• Inherited genetic mutations like BRCA2
• Geography - higher rates in North America and Europe

Factors that might influence your risk include diet, exercise, and body weight. Some studies suggest that men who eat lots of red meat and high-fat dairy products may have slightly higher risk, while those who eat more fish and vegetables may have lower risk.

Regular exercise and maintaining a healthy weight appear to offer some protection, particularly against more aggressive forms of prostate cancer. However, these lifestyle factors seem to have a smaller impact on prostate cancer risk compared to other types of cancer.

What are the possible complications of prostate cancer?

Complications can arise from the cancer itself or from treatments. Understanding these possibilities helps you prepare and make informed treatment decisions with your healthcare team.

Cancer-related complications may include:

• Cancer spread to nearby lymph nodes or bones
• Urinary incontinence if cancer affects bladder control
• Erectile dysfunction from nerve damage
• Bowel problems if cancer spreads to nearby organs

Treatment-related complications vary depending on your chosen therapy. Surgery might cause temporary or permanent incontinence and erectile dysfunction. Radiation therapy can cause fatigue, bowel irritation, and urinary problems. Hormone therapy may lead to hot flashes, bone thinning, and mood changes.

The encouraging news is that many complications are manageable with proper medical care. Your healthcare team will work with you to minimize risks and address any problems that arise during or after treatment.

How is prostate cancer diagnosed?

Diagnosis typically starts with a PSA blood test and digital rectal exam during your regular check-up. PSA stands for prostate-specific antigen, a protein made by prostate cells that can be elevated in cancer.

If these initial tests suggest possible cancer, your doctor will likely recommend a prostate biopsy. During this procedure, thin needles remove small tissue samples from different areas of your prostate. The samples are examined under a microscope to look for cancer cells.

Additional tests might include MRI imaging to get detailed pictures of your prostate, or newer tests like the 4Kscore or Prostate Health Index that provide more information than PSA alone.

If cancer is found, your doctor will determine its grade using the Gleason score system. This helps predict how quickly the cancer might grow and spread, guiding your treatment decisions.

What is the treatment for prostate cancer?

Treatment depends on many factors including your cancer's stage and grade, your age, overall health, and personal preferences. The good news is that you have several effective options to consider.

For slow-growing, low-risk cancers, active surveillance might be recommended. This means regular monitoring with PSA tests, exams, and occasional biopsies rather than immediate treatment. Many men do well with this approach, avoiding treatment side effects while keeping close watch on their cancer.

Surgery options include radical prostatectomy, where the entire prostate gland is removed. This can be done through traditional open surgery or minimally invasive robotic techniques. Surgery is often recommended for younger, healthier men with localized cancer.

Radiation therapy uses high-energy beams to kill cancer cells. External beam radiation is delivered from outside your body, while brachytherapy involves placing radioactive seeds directly into your prostate. Both approaches can be very effective for localized cancer.

For advanced cancer, hormone therapy blocks testosterone, which fuels prostate cancer growth. This treatment can shrink tumors and slow cancer progression, though it doesn't cure the disease.

Newer treatments like immunotherapy and targeted therapy are showing promise for certain types of advanced prostate cancer. Your oncologist can discuss whether these options might be appropriate for your situation.

How to manage prostate cancer at home?

Taking an active role in your care can help you feel more in control and potentially improve your outcomes. Simple lifestyle changes can make a meaningful difference in how you feel during treatment.

Focus on eating a balanced diet rich in fruits, vegetables, and whole grains while limiting red meat and high-fat foods. Good nutrition supports your immune system and helps maintain energy during treatment.

Stay as physically active as your doctor recommends. Regular exercise can help manage treatment side effects like fatigue, maintain bone strength, and improve your mood. Even gentle activities like walking or swimming can be beneficial.

Manage stress through relaxation techniques, meditation, or talking with a counselor. Cancer diagnosis and treatment can be emotionally challenging, and addressing stress helps your overall well-being.

Keep track of your symptoms and side effects, and don't hesitate to contact your healthcare team with questions or concerns. They're there to support you throughout your treatment journey.

How should you prepare for your doctor appointment?

Preparation helps you make the most of your appointment time and ensures you get the information you need. Start by writing down your symptoms, including when they started and how they've changed over time.

Make a list of all medications, vitamins, and supplements you take, including dosages. Bring a family medical history, especially noting any relatives who had prostate, breast, or other cancers.

Prepare your questions in advance. Consider asking about your specific risk factors, screening recommendations, what tests you might need, and what the results could mean for your health.

If you're discussing treatment options, ask about the benefits and risks of each approach, how they might affect your daily life, and what recovery looks like. Don't hesitate to ask your doctor to repeat or clarify anything you don't understand.

Consider bringing a trusted friend or family member who can help you remember important information and provide emotional support during the appointment.

What's the key takeaway about prostate cancer?

Prostate cancer is very common, but it's also very treatable, especially when caught early. Most men diagnosed with prostate cancer will not die from it, and many treatment options can help you maintain a good quality of life.

The most important step you can take is having regular conversations with your doctor about screening. Early detection gives you the most treatment options and the best chance for successful outcomes.

Remember that having risk factors doesn't mean you'll develop cancer, and a diagnosis doesn't mean your life is over. Medical advances have made prostate cancer much more manageable than it was even a decade ago.

Stay informed, but don't let fear drive your decisions. Work closely with your healthcare team to make choices that align with your values and goals. With proper medical care and support, you can navigate this journey successfully.
