Prostate Cancer Overview
Prostate cancer occurs in the prostate, a small walnut-shaped gland in males that produces seminal fluid to nourish and transport sperm.
It is one of the most common cancers, with many cases growing slowly and remaining confined to the prostate without causing significant harm. However, some types can be aggressive and spread rapidly.
Symptoms
In early stages, prostate cancer often presents no symptoms. Advanced stages may cause:
– Difficulty urinating
– Reduced urine flow
– Blood in urine or semen
– Bone pain
– Unintended weight loss
– Erectile dysfunction
When to See a Doctor
Consult your doctor if you experience any persistent, concerning symptoms.
Causes
Prostate cancer begins when DNA changes in prostate cells lead to uncontrolled growth and division.

These abnormal cells form a tumor that can invade nearby tissues and metastasize to other body parts.
Risk Factors
– **Age**: Risk increases with age, especially after 50.
– **Race**: Black individuals have a higher risk and are more likely to have aggressive forms.
– **Family History**: Increased risk if relatives have prostate cancer or if you have BRCA1/BRCA2 mutations.
– **Obesity**: May increase risk and likelihood of aggressive cancer, though evidence is mixed.
Complications
– **Metastasis**: Cancer can spread to other organs, bones, or tissues, causing pain and potential fractures.
– **Incontinence**: Both cancer and treatments can cause urinary issues, managed with medication, catheters, or surgery.
– **Erectile Dysfunction**: May result from cancer or its treatments, with options including medications, devices, or surgery.
Prevention
– **Healthy Diet**: Eat a variety of fruits, vegetables, and whole grains. While diet alone may not prevent prostate cancer, it supports overall health.
– **Avoid Supplements**: No evidence shows supplements reduce risk. Focus on nutrient-rich foods.
– **Regular Exercise**: Aim for regular physical activity to maintain weight and overall health.
– **Healthy Weight**: Maintain or achieve a healthy weight through diet and exercise.
– **Risk Assessment**: Discuss with your doctor if you have a high risk. Medications like 5-alpha reductase inhibitors may reduce risk but could increase the risk of high-grade cancer.
