Re-stating our Position on Vitamin B17

Ask Greg FAQ's, Blog Comments Off


I have (stage) IV breast cancer and I am doing well on Prejeta, Herceptin and Tomoxifin.  My last scan was NED. I was reading your book and following your nutrition and exercises as well as mind, body and spirit.

Your book I’m referring to is “Cancer: 50 Essential Things to Do.”  I really like your book and it has helped me greatly through my healing journey.

I did read that there was a vitamin curing stage four cancers called B17. I was wondering what your thoughts were about taking this vitamin, if it was safe and if you thought it would be a good idea to take while I am on Perjeta, Herceptin and tamoxifen?

Any advice would be greatly appreciated.



Dear Michelle,

I am not a fan of vitamin B17, also known as Laetrile and/or Amygdalin.  In over 20 years of following the claims made for this “cure,” I have never been able to talk to even one patient who can verify this is the reason for their recovery and survival.

The Cochrane Collaboration says:  The claims that laetrile or amygdalin have beneficial effects for cancer patients are not currently supported by sound clinical data. There is a considerable risk of serious adverse effects from cyanide poisoning after laetrile or amygdalin, especially after oral ingestion. The risk–benefit balance of laetrile or amygdalin as a treatment for cancer is therefore unambiguously negative.

You can find others who think differently.  Just Google “Vitamin B 17.  But my advice is, “No.”

Be well,

Greg Anderson

Hi Greg,

Many thanks for sharing your story and for being available to help others. I have ampullary cancer with liver and possible lung metastasis. Oncologists seem certain that I’m a goner, and recommend chemotherapy to keep me alive a bit longer. They have very little experience with this type of cancer, and say they generally treat it the way they would treat pancreatic cancer. I totally disagree with their prognoses, realizing that a certain, albeit small, percentage of people in my condition survive for the long term. I’m determined to be one of them, and I don’t think it will happen by accident. I will have to make it happen. Outwardly, my health is excellent. Vital signs are consistently normal, my color is good, my weight is holding steady and I’m doing a lot of walking and some weight lifting. My life partner/caregiver is totally wonderful and with me every step of the way; and my family is very supportive. I’m extremely grateful for all of these. I’ve had two months of chemotherapy with Gemzar and Cisplatin, which I tolerated very well. The most recent scan shows that the tumors grew slightly, and the oncologist said this could have happened between the time of the previous scan and the beginning of the chemotherapy, and wants to do six more weeks with Gemzar and Cisplatin. Meanwhile, I went to another treatment center, and while their approach was considerably better than others, the treatment plan was about the same. The only difference was that the CTCA oncologist said the scans make it clear enough that the current regimen is not working, and recommended going on to a more aggressive chemotherapy (Xeloda). He seemed slightly more optimistic about my long-term survival possibilities, but was not inspiring. I have strong misgivings about taking any more chemotherapy, given that several sources tell me it’s effective against only a handful of cancers, and mine isn’t one of them. Also, the oncologists prescribing it are not planning on my long-term survival, and chemotherapy attacks my health and immune system at a time when I might very well need them most. I also have strong misgivings about quitting chemotherapy, because it just might be attacking tumors that aren’t visible, and conventional medicine doesn’t seem to offer much else. Is this the time to quit chemotherapy, continue the previous regimen, or start a more aggressive regimen? Any guidance or encouragement would be greatly appreciated.




I cannot give you medical advice.  But I can tell you that the use of chemotherapy is third in effectiveness to surgery and radiation. 

Make sure you are in touch with the ampullary cancer survivors at

If you have read some of my books, you know that I am not a fan of chemo.  The facts do not support its widespread use.

Kerry, my guidance is this:  if you have not had the surgery, do so.  Think next of radiation seeds (brachytherapy).  And then chemo, perhaps fractionated doses in an attempt to stabilize the disease.   

Add to that a full holistic wellness program.  See below as a great starting point.  Build up your immune system.

You have the perfect attitude.  Survivors are fighters.  And you are certainly a warrior.

Stay in touch.  I wish you well.

Dear Greg,

Is there any way to raise your white blood count after chemotherapy?


Hello Elaine,

Low white blood cell (wbc) counts typically resolve themselves although it may take a week or more to reach acceptable levels following high-dose chemo.

The orthodox method is the Neupogen or Neulasta injections.  They have a place if the wbc reach critically low levels.

Instead of those injections, I tend to favor a super-healthy diet of cooked, NOT RAW, veggies of a variety of rich colors.  Uncooked food is a risk because of potential infections.  Plus add lots of water, a glass every waking hour. 

Since the biggest risk of low wbc is infection, stay away from crowds and people who are sick with colds or flu-like symptoms–think children.

Finally, I’d add a big dose of “joy” each and every day.  Doing something that makes one’s spirit soar results in one’s immune system doing likewise.




Dear Mr. Anderson,

I’m scared. I write because you represent such hope to me. I’m not quite sure how to solidly put one foot in front of the other. I have a recurrence of cancer. I’m getting information that chemotherapy is the best treatment. So, after reading your book, I’ve asked about “fractionated chemotherapy” and they’ve agreed that this is a great idea. Do you know the Block Treatment Center here in Chicago? Do you know any survivors who live in Chicago and would hold my hand or pray with me?  I am profoundly grateful that you make possible a place for me to write this.



Dear Susan,

I am going to answer this email with several short but powerful health-producing truths:

1.  Recurrence does not equate with death.

2.  Recurrence calls for reassessment.  Carefully examine your doctors, diet, exercise, mind/body, relationships, meaning/purpose in your life.  Study the pyramid on the website.  Reassess your entire life.

3.  You do not state what type of cancer you are dealing with.  While fractionated dose chemo may be the correct medical treatment, it is even more critical to “create wellness” in your life.

4.  The Block Treatment center is well-known and I respect their work.

5.  We have survivors throughout Greater Chicago.  What type of cancer are you dealing with?  In what area of Chicago do you live?

6.  Please try at least one of our tele-support group sessions.  Information is on the website.

7.  We will add you to the prayer list and people around the globe will immediately begin praying for God’s will to be made real in your life.

8.  Thank you for thanking me and the entire CRF team.  We believe in hope, health and healing.  We believe it is possible for you!  Join us.




Dear Greg,

My husband has stage IV lung cancer and I need hope and faith.  He has a good attitude but is physically declining.  I need help to keep my spirits up as I am an exhausted caregiver.

Thank you.


Dear Andrea,

Take time for yourself each and every day.  You cannot be strong for another if you are weak yourself.  I wish you well.

Greg Anderson



Dear Greg,

My husband had nasopharangeal cancer. He had surgery and radiation. He lost 50lbs and has gained 10lbs back. He has little saliva–the taste has improved. I would like to know if anyone with this problem has had any help. He did have acupuncture which helped some. Bob is a runner and active –not having the saliva is a big problem. I am praying for a miracle. 


Dear Winnie,

Dry mouth is an ongoing challenge.  What works for some may not help others.  Some of the major answers include:

Try easy-to-swallow foods:  steamed vegetables (use microwave steamer bags or a microwave steamer), pasta with any kind of sauce, baked sweet potatoes, protein shakes/smoothies, shrimp, crabmeat and stir fry dishes.

Foods you may wish to avoid:  anything breaded, grilled steaks, fried chicken, fried fish and most breads.  And always carry a bottle of water.

Try the prescription med called Salagen (pilocarpene).

Try the Biotene products; toothpaste, mouthwash and others. You can find them at drug stores. 

My best,

Greg Anderson



Hi Greg,

I need some advice.  My wife has been diagnosed with Metastatic breast cancer; both bone and liver are involved.  We live a few miles outside of Jackson, MS.  She has looked at treatment centers including Cancer Treatment Centers of America in Zion, IL and MD Anderson in Houston, TX.  She really likes the Cancer Treatment Center of America approach of complementary medicine therapies and conventional therapies.  She is afraid that MD Anderson does not offer complementary medicine therapies along with conventional so she is ready to write off MD Anderson based on that theory. I on the other hand believe that MD Anderson would be the best place since I personally know people that have had cancer treatment there with great results.  Could you please help me with this? 




Difficult though it may be, you need to defer to your wife’s conviction. 

I know both of these places well.  They both do good work.  The advantage of MD Anderson is the research they do.  The advantage of CTCA is their holistic approach.

In the end, your wife’s belief is probably the deciding factor.  I encourage you to support her convictions, John.

Keep looking up,




Dear Greg.

What do I do when I am in remission? I had stage 3 asytoma.



The first thing I want you to do is live gratefully.  Remission!  The cancer is not progressing!  That is something to be very grateful about.  Gratitude changes our experience of life quicker than any other attitude.

Then go to the website to download the Cancer Recovery Contract. Sign it and keep it in a place where you will see it everyday.  Implement what the contract calls for.  It will maximize your health and your life.

Finally, do something that brings you true joy each and every day.  Feel the joy.  When you do, that life and love will sustain the well-being that you seek.

I wish you all “green lights.”

My best,

Greg Anderson



Dear Greg,

About what percentage of people in the world die of cancer?



The statistics are not clear as most countries do not have adequate cancer registries. 

The best source is the World health Organization.  You can check their information at

Prostate Cancer FAQ’s

Ask Greg FAQ's Comments Off

Dear Greg,

8 weeks after prostate removal, my PSA is 1.2  After my next PSA I will see my cancer doctor (I think).  What is the next step, and if my PSA is 1.2 or higher, what does that mean? Can it cause nerve twitching in my legs?



PSA at 1.2 is safe and requires no action.  Only at 4.0+ is PSA a problem–and then only if it is consistently rising.  The twitching in the legs is probably temporary and related to the surgery.

Next steps:  diet and exercise.  Prostate cancer responds.


Dear Greg,

Ten years ago my husband had seed implant for prostate cancer.  Now the doctors have discovered an enlargement on his prostate as well as a “red spot” on his K7 vertebrae.  We have searched the internet and found an alternative cancer treatment center (3 week treatment in house) costing approx $6,500 per week.  Do you know of any foundations/groups/trusts that we could apply to for financial assistance?  Please reply.  Thank you.  This is quite important.

Dear Patricia,

I have been asked this question for years.  Unfortunately, I do not know of any organizations who offer financial assistance for alternative cancer treatments.

Most alternative cancer programs offer scholarships, discounts and deferred payment programs to qualified applicants.  I suggest you make your need known to them directly.

Now I add a point of personal advice based on 20 years of observations:  all of the detoxification and nutritional regimens offered by alternative cancer centers are reasonably simple practices you can and should be doing from the comfort of your own home. 

Prostate cancer responds well to these efforts, especially when implemented in conjunction with a low-impact exercise program.  I have attached our nutritional support guidelines for your consideration.  Get rid of the sugars and load up on the veggies.  “Whites out.  Greens in.”  That may sound simplistic but unless you are doing this, you are not maximizing the nutrition/detox alternatives.

In addition, you may wish to contact a naturopathic physician in your area.  They may guide you to consider other minimally-invasive, less-toxic alternatives which you seek.  Ask specifically about IP-6, Inositol.  These alternatives can be implemented at a fraction of the quoted costs.  I believe they are equally effective.

In short, prostate cancer is a highly-manageable disease.  There are numerous lower-cost comparably-effective options available to you.  Please consider them before you pay $20,000+ to a clinic.  I believe you can get well and stay well.

Keep looking up,

Greg Anderson
