Prostate cancer is metastatic if it has spread to distance tissue and organs. Prostate cancer often spreads to the bones, lymph nodes, liver, and lungs and rarely moves to other organs.
A range of therapeutic options including hormone ablation, chemotherapy, autologous immunotherapy, and radiation therapies are offered to affected patients and show marginal benefits.
Despite sharing cancer cells with the original prostate tumor, metastatic prostate cancer is resistant to conventional treatments, posing questions about its chances of spreading and responding to therapies. Unfortunately, there is currently no cure for metastatic prostate cancer post-radical treatment or hormone ablation therapy.
To address the challenges of prostate cancer spreading, patients and healthcare providers may consider exploring natural supplements and lifestyle changes. Preliminary studies suggest potential benefits from pomegranate, lycopene, and Omega-3 fatty acids in managing prostate health, aiming to halt or slow the progression of prostate cancer.
Understanding the signs and sites of prostate cancer metastasis is essential for effective management. While current therapies offer limited benefits, research on natural interventions continues, emphasizing the need for further exploration into their efficacy.

Prostate Cancer Spreading Illustration
Metastatic prostate cancer, marked by the spread of cancer to distant tissues and organs such as bones, lymph nodes, liver, and lungs, poses significant challenges. Understanding the selective spread remains crucial, and exploring mechanisms may hold the key to prevention.
How is metastatic prostate cancer diagnosed?
Prostate Biopsy
A prostate biopsy is required to confirm the presence of and determine the aggressiveness of the cancer cells. The pathologist will give a Gleason score to your prostate cancer.
High scores above eight indicate aggressive cancer that is likely to spread to other organs.
Further, recent advancement in cancer detection and monitoring makes it possible to use genetic tests to determine the risk of your prostate cancer spreading quickly more accurately.
Additional Tests
Once the prostate cancer stage has been determined, your doctor works to assess the presence of metastasis. If your medical team suspects your cancer has spread to other organs, they will offer you additional tests like;
• Bone scan
• Computerized (CT) or positron emission (PET) tomography scans
• Ultrasound
Getting these scans will depend on individual cases, and your medical provider will help you determine the best scan.
Treatments for metastatic prostate cancer
Localized prostate cancer typically undergoes radical prostatectomy or radiation therapy. However, the progression to locally advanced or metastatic stages often necessitates hormone or radiation therapy.
Hormone Therapy and its Challenges
Hormone therapy, reducing androgen levels to inhibit prostate cancer cell growth, may be coupled with external beam radiation therapy for advanced disease post-chemical or surgical castration. However, the emergence of metastatic castration-resistant prostate cancer (CRPC) remains a challenge, with patients often requiring second-line therapies like anti-androgens (enzalutamide) and CYP17 inhibitors, each with distinct side effects requiring careful management.
Chemotherapy and Emerging Therapies
Chemotherapeutic agents like docetaxel and cabazitaxel offer limited benefits in metastatic CRPC, emphasizing the ongoing pursuit of less toxic options. Sipuleucel-T, a personalized immune therapy, shows modest improvements in overall survival, while radium-223 dichloride and zoledronic acid address bone metastasis but with specific limitations.
Towards Novel Approaches
With limitations and side effects inherent in current therapies, there is a growing emphasis on identifying novel natural therapies for metastatic prostate cancer. The need for continued research and innovative treatment options is underscored by the challenges presented by the adaptation of prostate cancer cells to low androgen levels, leading to the development of metastatic CRPC.
Symptoms of metastatic prostate cancer
The progression of prostate cancer to advanced metastatic disease can cause many health problems depending on the site and how quickly the cancer is spreading.
Localized Cancer Spread Signs
- urinary problems such as urinary retention and associated infection.
- Further, bowel problems often develop when prostate cancer spreads to the bowel and rectum. Complications like constipation and diarrhea can reduce your quality of life.
Signs of Prostate Cancer spreads to bones and lymph nodes
Beyond local metastases, prostate cancer often spreads to the bones, lymph nodes, liver, brain, and lungs. Men with metastatic castration-resistant prostate cancer have an increased risk of distant metastasis, which is associated with debilitating complications.
Bone metastasis and Bone Marrow
This accounts for 85% of metastasis sites. The bone matrix is a very common target organ. It attracts cancer cells as a blood and nutrient-rich area where they can easily thrive.
Significant pain and increased risk of fracture are common because cancer cells weaken the bone.
The bone marrow is the production house of blood cells; thus, the spread of prostate cancer cells to the bone marrow can reduce oxygen-carrying red blood cells (Anaemia).
Hypercalcemia
Excessive calcium in the blood can also develop following bone metastasis, leading to vomiting, dehydration, and loss of appetite.
Cancer-associated anemia
Cancer-associated anemia can cause fatigue, breathing complications, and in severe cases, organ failure due to lack of oxygen.
Some of these complications can also occur when prostate cancer spreads to the liver, while the complications associated with lung metastasis are commonly confounded with other factors.
Spread of Prostate Cancer to Lymph Nodes
Finally, the spread of prostate cancer to lymph nodes not only increases the risk of further spread to other organs but can also block the transport of lymph and cause swelling.
When to go to doctors
Common Symptoms
In many patients, early-stage prostate cancer presents with no symptoms and are only identified through PSA informed tests. For men with symptoms, this will usually include;
• Blood in either urine or seminal fluid
• Sitting discomfort caused by an enlarged prostate
Though other non-cancerous conditions such as enlarged prostate and prostate inflammation can cause similar symptoms, it is better to get checked by your doctor if you experience the above symptoms.
These conditions are also linked with prostate cancer development, requiring you to treat them to avoid further complications.
Rare Cases Symptoms
In rare cases, patients will have advanced prostate cancer which may have symptoms of metastatic prostate cancer including;
• Swelling in the legs
• Weight loss and fatigue
• Bowel problems
It is important to note that some therapies for managing prostate cancer can cause these symptoms.
For instance, Zoledronic acid used to treat high blood calcium, and bone breakdown can also cause diarrhea and fatigue. You should speak to your doctor about your symptoms.
How important is it to catch metastatic prostate cancer early?
It is important to consult with your doctor if you experience any of these changes mentioned above.
This will help your doctor detect prostate cancer early and stop it from developing to advanced lethal disease.
Early cancer detection is central to the management of all cancers, including prostate cancer.
Currently, the treatment goal of advanced and metastatic prostate cancer is to slow cancer growth and spread.
In the absence of a definitive cure, it is critical to detect metastatic prostate cancer early to increase the usefulness of current management approaches.
Supplements and lifestyle changes may help you enhance the effectiveness of those therapies.
Best supplements to treat metastatic prostate cancer
Several natural supplements, including lycopene, pomegranate, omega-3 fatty acids, and green tea have shown anti-metastatic properties and promising results in clinical trials.
Plant phenolic compounds can help you fight prostate cancer and help slowing down the development of metastasis. (Dagogo-Jack and Shaw, 2018).
1. Lycopene
Anti-Cancer Properties: Lycopene demonstrates significant anti-cancer activity, reducing the risk of various cancers, including skin, breast, lung, prostate, and liver cancers. This is achieved through the reduction of oxidative stress and inflammation (Coates et al., 2004; Khan et al., 2008).
Modulation of Disease Progression: Studies on advanced prostate cancer reveal that lycopene effectively modulates markers associated with disease progression and recurrence.
Inhibition of Tumor Growth: Pre-clinical trials on mice with androgen-independent metastatic prostate cancer cells demonstrate that lycopene can decrease tumor growth, showcasing its potential in treating metastatic prostate cancer (Tang et al., 2011; Yang et al., 2011, 2012).
Cell Adhesion Enhancement: Lycopene metabolites released during breakdown enhance cell adhesion, promoting attachment and communication between cells. This mechanism is crucial in preventing metastatic prostate cancer cells from detaching and invading distant organs (Mein et al., 2008).
Anti-Migratory Effect: Lycopene’s anti-migratory effect, combined with its antioxidant properties, may aid in combating metastatic prostate cancer, offering better outcomes for individuals with localized prostate cancer compared to those with advanced disease.
PSA Level Reduction: Clinical trials, including a phase II trial, demonstrate that lycopene supplementation can reduce prostate-specific antigen (PSA) levels in men with prostate cancer. This reduction in PSA levels suggests potential benefits in fighting metastatic prostate cancer (Zhang et al., 2014; Barber et al., 2006; Kucuk et al., 2002).
Combination Therapy Potential: Combining lycopene supplementation with radical treatment, such as orchiectomy, shows promising results in reducing PSA levels and primary and secondary tumors in patients with metastatic prostate cancer (Ansari and Gupta, 2003).
Dosage Consideration: Studies emphasize the importance of considering patient heterogeneity and lycopene dosage, with variations in clinical benefits observed at different doses (Schwenke et al., 2009; Bunker et al., 2007; Gann et al., 2015).
Markers Modulation: The available evidence from pre-clinical and clinical trials indicates that lycopene supplementation can effectively modulate markers associated with metastatic prostate cancer, potentially reducing the risk of its development.
Personalized Cancer Prevention: While further trials are needed to address dosage discrepancies, the collective findings suggest that incorporating lycopene into supplementation regimens can be beneficial in personalized cancer prevention strategies.

2. Pomegranate
Anti-Oxidant and Anti-Cancer Activities: Pomegranate fruit is rich in bioactive polyphenolic ellagitannins, exhibiting potent anti-oxidant and anti-cancer properties (Coates et al., 2004; Khan et al., 2008).
Inhibition of Prostate Cancer Growth: Phenolic compounds derived from pomegranate inhibit the growth of prostate cancer cells, similar to lycopene (Gasmi and Sanderson, 2010).
Testosterone-Stimulated Cell Inhibition: Pomegranate extract effectively kills testosterone-stimulated prostate cancer cells and induces cell-cycle arrest in various prostate cancer cells (Koyama et al., 2010; Turrini et al., 2015).
Modulation of Metastasis: Pomegranate extract can modulate key aspects of cancer metastasis, impacting cell adhesion and the epithelial-to-mesenchymal transition (Rocha et al., 2012).
Reduction of Inflammatory Mediators: Globally, pomegranate extracts reduce pro-inflammatory mediators, potentially inhibiting the establishment of new metastatic niches.
Inhibition of Cell Migration and Invasiveness: Studies demonstrate that pomegranate juice significantly reduces the migratory and invasive properties of prostate cancer cells, achieved by reducing an enzyme crucial for prostaglandin production (Lansky et al., 2005; Kessenbrock et al., 2010).
Increased PSA doubling time: Clinical trials involving pomegranate juice show a significant increase in the doubling time of prostate-specific antigen (PSA), indicating a potential slowdown in prostate cancer progression (Pantuck et al., 2005).
Slowing PSA Increase in Recurrent Prostate Cancer: Recent randomized trials of multicomponent food supplements containing pomegranate extract show a slowing of PSA increase in men experiencing prostate cancer recurrence (Paller et al., 2017).
Clinical Benefits Without Adverse Effects: Extract/juice of pomegranate demonstrates clinical benefits, such as increased PSA doubling time, without inducing adverse effects in patients with rising PSA and no metastases (Paller et al., 2013).
3. Multicomponent dietary supplements
Various studies have explored the potential benefits of multi-component supplements, incorporating plant-based ingredients, in potentially slowing the progression of prostate cancer to a more advanced stage.
For instance, a placebo-controlled and randomized trial assigned 199 men with localized prostate cancer to either a food supplement containing pomegranate, green tea, broccoli, and turmeric or placebo control for 6 months (Thomas et al., 2014).
The study reported a significant reduction in PSA in the food supplement group compared to the placebo.
These ingredients were derived from raw and dried plant materials and cause no adverse events.
Similarly, a mixed daily supplementation with 35 mg lycopene, 55 ug selenium, and 600 mg green tea catechins showed some clinical benefits, albeit to a lesser extent (Gontero et al., 2015).
What are some supplements that can help you prevent prostate cancer?
Though genetic/epigenetic changes can influence the development and progression of prostate cancer, diet and nutrition are very important in the development of many cancers.
Inadequate levels of important antioxidants and dysfunctions in the body’s detoxification systems can increase your risk of developing prostate cancer.
In addition to lycopene and pomegranate, other supplements like Vitamin D and Omega-3 fatty acids can reduce your risk of developing prostate cancer.
Vitamin D has been shown to reduce the risk of prostate cancer development and progression by reducing oxidative stress and inflammation (Posadzki et al., 2013).
Similarly, polyunsaturated Omega-3 fatty acids can reduce oxidative stress and inflammation (Berquin et al., 2007), reducing the risk of prostate cancer development.
These supplements not only protect you from prostate cancer but also cancers occurring in other organs.
Conclusion
The causes of prostate cancer remain largely unknown, making it difficult to prevent its development. However, diet, supplements, and physical activity are natural ways to reduce your risk.
It’s important to note that a diet high in red meat and dairy products may increase the risk of prostate cancer, while incorporating tomato products and fatty fish into your diet may have a potential protective effect.
The accumulating evidence suggests that you can use lifestyle changes to modify the risk of prostate cancer.
Specifically, high body mass index (BMI) is strongly associated with cancer development and progression. Prostate cancer patients with high BMI are more likely to progress to lethal/metastatic prostate cancer independent of clinical factors.
Consistently, a low-fat diet rich in fruit and vegetables can lower your risk of prostate cancer. Consider reducing your consumption of meat, oils, and dairy products.

Reducing your BMI can reduce your prostate cancer-specific mortality and recurrence by more than 20% (Cao and Ma, 2011). The importance of healthy BMI is highlighted in the observation that weight gain after a prostate cancer diagnosis is associated with poor patient outcome (Bonn et al., 2014).
An active lifestyle can positively modify key components of prostate cancer development, including oxidative stress, inflammation, and immune function.
Indeed, studies have consistently shown that an active lifestyle can reduce your risk of developing prostate cancer. Preventing prostate cancer development is perhaps the best way to prevent metastatic prostate cancer.
You should aim to maintain a healthy weekly activity level to reduce your risk of developing lethal prostate cancer.
Activities that increase your heart and respiratory rates such as cycling, jogging, and swimming can reduce your prostate cancer risk by up 65% compared to men with lower weekly activity (Kenfield et al., 2011).
