Your Prostate Cancer Handbook

At any time during your prostate cancer experience

Throughout your cancer experience, you may turn your attention to boosting your health and resilience and also creating a body that is less supportive of cancer. You may need to evaluate and address symptoms such as anxiety, depression, and stress.

Also see separate sections in this handbook about further recommendations and approaches you can use at specific times during your cancer experience.

Top practices and therapies we have reviewed for improving cancer outcomes and body terrain at any time

Your body terrain is the whole environment in which your cancer grows and includes specific terrain factors that can impact cancer growth and development.

These practices and therapies have at least modest evidence for the medical benefits listed. We add to this list as we complete new reviews of practices and therapies.

Improving cancer outcomes

We present self-care practices and complementary therapies supported by evidence to promote better cancer outcomes or body terrainthe internal conditions of your body, including nutritional status, fitness, blood sugar balance, hormone balance, inflammation, and more. Those with the best evidence are presented first.

A practice or therapy may show a stronger effect or have more evidence in some situations than in others. The evidence supporting the effects for each practice or therapy is listed in the full reviews available through the image links.

Strong, good, or modest evidence of benefit for cancer outcomes

Strong evidenceconsistent, significant effects in several large (or at least one very large) well designed clinical studies or at least two meta-analyses of clinical studies of moderate or better quality (or one large meta-analysis) finding similar results (this is the CancerChoices definition; other researchers and studies may define this differently) indicates confidence that the practice or therapy has an effect as noted. Good evidencesignificant effects in one large or several mid-sized and well-designed clinical studies (randomized controlled trials (RCTs) with an appropriate placebo or other strong comparison control or observational studies that control for confounds) (this is the CancerChoices definition; other researchers and studies may define this differently) indicates that the practice or therapy is linked to the outcomes described with reasonable certainty. Modest evidencesignificant effects in at least three small but well-designed randomized controlled trials (RCTs), or one or more well-designed, mid-sized clinical studies of reasonably good quality (RCTs or observational studies), or several small studies aggregated into a meta-analysis (this is the CancerChoices definition; other researchers and studies may define this differently) means the practice or therapy may be linked to the outcomes described, but with a lower degree of certainty.

Eating Well: modest to weak evidence

• Lower risk of Gleason grade progression among men with low or low-intermediate risk prostate cancer eating a baseline diet higher in total fruits, whole fruits, total vegetables, greens and beans, whole grains, dairy, total protein foods, seafood and plant proteins and unsaturated to saturated fatty acids ratio and/or lower in refined grains, sodium, added sugars and saturated fats (modest evidence)
• Lower cancer-specific mortality among men with non-metastatic prostate cancer eating higher levels of vegetable fats after diagnosis and higher all-cause mortality among men with non-metastatic prostate cancer eating higher levels of saturated and trans fats (modest evidence)
• Slightly lower androgen levels among people with prostate cancer eating a low-carbohydrate diet (preliminary evidence)
• Increased risk of progression among people with prostate cancer eating eggs or poultry with skin, but no evidence of an effect with other types of meat (preliminary evidence)
• Longer prostate specific antigen (PSA) doubling time among people drinking pomegranate juice (weak evidence)
• PSA stabilization among people eating more tomato-based foods and taking soy supplements (weak evidence)

Cancer as a whole:

• Better survival among people with cancer as a whole following the recommended diet patterns of increasing vegetables and fruits and reducing red meat, processed foods, and saturated fats (modest evidence)

Moving More: mixed evidence

Cancer as a whole:

• Moderately better survival with cancer as a whole among people with higher activity levels after diagnosis (good evidence)

Sleeping Well: modest evidence

Sharing Love and Support: good and modest evidence

Manage anxiety: good evidence

Manage high blood sugar and insulin resistance: modest and preliminary evidence

Solid tumors as a whole:

• Slightly higher mortality among people with solid tumors with diabetes (good evidence)

Aspirin: mixed evidence

Cancer as a whole:

• Lower mortality among people with adenocarcinoma using aspirin regularly, particularly among those without metastasis, and with greater benefit among people who smoke (strong evidence)
• Better progression-free survival but no evidence of an effect on overall survival among people with cancer as a whole treated with low-dose aspirin during treatment with immune checkpoint inhibitors (good evidence)

Metformin: mixed evidence

Cancer as a whole:

• Lower cancer-specific mortality among people with diabetes treated with metformin (modest evidence)
• No evidence of an effect on survival among people with cancer (not specific to diabetics) treated with metformin in addition to immune checkpoint inhibitors in a combined analysis of studies

Vitamin D: good to weak evidence

Cancer as a whole:

• Moderately better cancer-specific survival among people with cancer with high vitamin D levels (good evidence)
• Lower cancer-specific mortality among people with cancer using vitamin D supplements after diagnosis (weak evidence)
• Lower overall mortality among people with cancer taking vitamin D supplements (modest evidence)

Preliminary or weak evidence of benefit for cancer outcomes or body terrain

Preliminary evidencesignificant effects in small or poorly designed clinical studies OR conflicting results in adequate studies but a preponderance of evidence of an effect (this is the CancerChoices definition; other researchers and studies may define this differently) means the practice or therapy may be linked to the outcomes described, although substantial uncertainty remains. Weak evidenceone or more case studies, supported by animal evidence OR small treatment effects of limited clinical significance OR studies with no controls OR weak trends of effects (this is the CancerChoices definition; other researchers and studies may define this differently) may mean that the effects are small or that a high degree of uncertainty remains about the links between the practice or therapy and the outcomes described.

No evidence or insufficient evidence of benefit for cancer outcomes

Ketogenic diet ›

Cancer as a whole:

• Insufficient evidence of anticancer effects with cancer as a whole among people eating a ketogenic diet

Reishi mushrooms ›

Specific to prostate cancer:

• No evidence of an effect on prostate-specific antigen (PSA) levels among men with prostate cancer treated with reishi mushrooms in a preliminary trial

Support groups ›

Cancer as a whole:

• No evidence of an effect on survival among people with cancer as a whole participating in support groups with their family caregivers in a combined analysis of studies

Intravenous vitamin C ›

Advanced prostate cancer 

• No evidence of anticancer effects among people with metastatic castration-resistant prostate cancer treated with infusions of ascorbic acid in an uncontrolled trial

Optimizing your body terrain

Your body terrain is the whole environment in which your cancer grows.  

See these completed body terrain handbooks for information about the connections between these factors and cancer, and for guidance on improving your body terrain. You can do much on your own, but professional healthcare management may also be necessary. Find health professionals who specialize in managing body terrain ›

We’re building more handbooks on body terrain.

Managing symptoms and promoting wellness

Self-care practices, supplements, mind-body therapies, and other complementary therapies may reduce symptoms and enhance your quality of life all throughout your cancer experience.

For some symptoms, we have complete handbooks, as linked below. For other symptoms and for quality of life and physical function as a whole, we list here the effects of complementary therapies and practices we’ve reviewed.  

We report the evidence relating to benefits from using these practices and therapies. Please also review the Safety and precautions page within the linked reviews for guidance on safe use. We recommend supervision from a medical professional trained in the use of complementary therapies.  

Strong evidenceconsistent, significant effects in several large (or at least one very large) well designed clinical studies or at least two meta-analyses of clinical studies of moderate or better quality (or one large meta-analysis) finding similar results (this is the CancerChoices definition; other researchers and studies may define this differently) indicates a high degree of confidence that the therapy is linked to the outcomes as noted. Good evidencesignificant effects in one large or several mid-sized and well-designed clinical studies (randomized controlled trials (RCTs) with an appropriate placebo or other strong comparison control or observational studies that control for confounds) (this is the CancerChoices definition; other researchers and studies may define this differently) indicates a relatively high degree of confidence that the therapy is linked to the outcomes as noted.

Preliminary evidencesignificant effects in small or poorly designed clinical studies OR conflicting results in adequate studies but a preponderance of evidence of an effect (this is the CancerChoices definition; other researchers and studies may define this differently) typically indicates that not much research has been published so far, although the outcomes may be meaningful. Weak evidenceone or more case studies, supported by animal evidence OR small treatment effects of limited clinical significance OR studies with no controls OR weak trends of effects (this is the CancerChoices definition; other researchers and studies may define this differently) may mean that the effects are small or that only very preliminary research has been published.

A therapy may show a stronger effect or have more evidence in some situations than in others. The evidence supporting the effects for each therapy is listed in the full reviews available through the links.
