Prostate Cancer: The Science of Prevention & Treatment | Dr. William Li

Prostate cancer is one of the most common cancers in men, but emerging research shows that the body has powerful, natural mechanisms to prevent and slow its growth. In this episode of Dr. Li Unplugged, I break down the science behind angiogenesis—the process by which tumors hijack the body’s blood supply to grow—and explain how food and lifestyle choices can help regulate this process.

In This Video, You’ll Learn:
✔ The role of angiogenesis in cancer development and how the body naturally suppresses microscopic tumors. (00:40)
✔ How prostate cancer forms—and why most cases remain harmless while others become aggressive. (08:38)
✔ Lycopene-rich foods (tomatoes, watermelon, guava) reduce prostate cancer risk by 29% in large-scale studies. (12:09)
✔ Tree nuts (walnuts, almonds, cashews) contain bioactives that inhibit tumor blood supply. (14:30)
✔ Ferulic acid and caffeic acid (found in coffee, spinach, beets) have been shown to modulate angiogenesis. (15:08)
✔ The impact of exercise—how it lowers inflammation, boosts immunity, and improves cancer defenses. (22:45)
✔ Key risk factors that contribute to prostate cancer, including inflammation, smoking, and environmental toxins. (23:49)

I really appreciate how this video doesn’t just focus on the problem but also provides practical solutions. Learning about foods that can help prevent prostate cancer—like tomatoes, nuts, and green tea—is so valuable. Small, everyday choices really do add up when it comes to long-term health!

Minutes 12~ 26 /. Foods that help by cutting-off blood supply to prostate tumors are 1- Lycopene found in cooked red tomato sauce 2~3 times weekly. 2- a daily handful of tree nuts like Walnuts, brazil nuts, Almonds, pine nuts & Legumes 🫘 and Omega3 supplements. 3- Ferulic Acid in eggplant, spinach, beets as well as. 4- Cafeic Acid found in Coffee or Dark Chocolate. In short { Mediterranean Diet }. 5- Other foods like Celery, Capers, Oregano and Apples etc . . 5- foods rich in dietary fiber ( soluble & non-soluble ) coz they feed our microbiome and work by reducing inflammation 6- Colorful veggies, vegetable greens wide range & berries 👍 7- foods that improve immunity like violet onions, garlic, mushrooms، cruciferous veggies : broccoli sprouts, mushrooms, cabbage, cauliflower etc . . 8- and of course Xtra-Vergin Olive Oils. 9- beside food we need to Exercise regularly ( but don’t trigger angiogenesis by overworking or causing trauma to the neighborhood of prostate like riding horses without a cushion 😂 ) 10- Manage stress and get enough quality sleep.

Thank you doctor. I was diagnosed with low-grade prostate cancer two years and changed my diet. I cut out red meat, chicken, eggs and dairy. I switched to a pescatarian diet (fish, vegetables, fruit, healthy fats like olive oil, nuts avocados etc. I lift weights, do daily brisk walking and run hill sprints twice a week. My PSA levels have remained steady and am still on active surveillance. I'm feeling good and in great physical shape for 64! Thank you for reinforcing that I'm on the right track!👍

For everyone reading this, finding the banned book called “the hidden herbs” by anette ray should be your top priority

🌟 Absolutely eye-opening, Dr. Li 🌟

I’ve never heard angiogenesis explained in such a simple, powerful way—connecting blood vessels to prostate cancer risk and prevention blew my mind. The idea that microscopic tumors need to hijack our blood supply to grow really shifted how I think about early cancer prevention.

Also, the science behind lycopene, tree nuts, and even coffee? That’s the kind of practical knowledge every man over 50 needs. I’m heading straight to the kitchen for tomatoes and walnuts. 🍅🥜

This wasn’t just informative—it was empowering. Thank you for giving us real science without the fluff. 🙏

Anyone else here changing their grocery list after this? Let’s share tips—what foods are you adding first?

Great video ! you have to wonder about the PSA test (which is basiclly a crap shoot) if 50% of men over 50 are walking around with small tumors less than 2-3mm...that is the problem with the PSA test, the powerful imaging ability of the MRI and the general lack of knowledge in the general public regarding diet and health. Also the emotion surounding the word "cancer" which I think the medical industry plays off somewhat.

Very informative video! For those in a hurry, the first half discusses the importance of preventing angiogenesis (creation of new blood vessels) around tiny tumors most of us have to prevent their growth.
The second half covers nutrients that do that -- lycopene (in tomatoes, watermelon, guavas, pink grapefruit), ALA omega 3s (in tree nuts), ferulic acid (in eggplants, spinach and beets), caffeic acid (in coffee), foods high in fiber and antioxidants and broccoli sprouts.

Hi Doc, I've watched your program and it is very educational, is it possible to list for us the auto immune food that we can eat to prevent inflammation and cancer.

@johnsmerdon-p4d 4 hours ago

I know you mentioned exercise but the foods is important for me .i heard you mentioned cooked tomatoes, what about raw tomatoes will that also do.?

@wakabuilder 1 year ago

I LIKED THE TALK ON PROSTRATE CANCER. I GOT A LOT SMARTER AND MORE KNOWLEDGEABLE ON THE TOPIC.

Thanks again

not enough people are talking about anette ray and the hidden herbs… that book is next level

I have prostate cancer and have been using food as medicine to treat it. I in my last MRI the original lesion they were concerned about had resolved itself and a newer lesion was unchanged. PSA has not dropped yet but urine flow and bladder emptying are better than they have been for 20 years. your book started me on the right path. Thanks

Outstanding! I have already been doing much of what you recommend. Your additional information on how cancer spreads was really helpful. Keep up the good fight.
