Breast cancer is a major and growing health issue among women. Invasive breast cancer is the most common type cancer affecting women worldwide, and the second-most-common type overall, according to the Susan G. Komen foundation. This year, an estimated 232,000 cases will be diagnosed just in the US. Early detection and successful treatment are crucial for survival.
According to doctors and patients we have worked closely with, breast cancer tumors can be effectively treated with cannabis oil. However, they caution, the ratios of the tumor-busting cannabinoids THC and CBD must be matched to the classification of breast cancer—with certain kinds of breast cancer, namely those that are estrogen-
positive, the tumor could actually grow if too much THC is used.
Although there are many types of breast cancer, they are usually grouped into four categories, depending on how they show up on diagnostic tests:
- Estrogen receptor positive (ER+) or progesterone receptor positive (PR+): About two in three cases of breast cancer (more in older women) have receptors for one or both of these hormones.
- HER2/neu (a.k.a. HER2 or ErbB2): HER2/neu is a protein that is over-copied by certain types of breast cancer. HER2-positive cancers spread more rapidly than other types of cancer.
- Triple negative: These breast cancers do not have estrogen or progesterone receptors and don’t show overproduction of HER2. Triple-negative breast cancers spread aggressively because they don’t respond to hormones or drugs that target HER2, but chemotherapy is an option.
- Triple positive: These types of breast cancer are ER+ and PR+, and they have too much HER2 production. They can be treated with hormones, HER2 drugs, and chemo.
Research has shown that PR+, HER2-positive, and triple-negative breast cancers can be effectively treated with cannabis. The protocols recommended by doctors we work with tend to have high CBD-to-THC ratios, often around 4:1.
Cancers that involve estrogen, however, may actually spread in response to large amounts of THC. Patients with ER+ or triple-positive breast cancer do better with lower ratios of THC to CBD—a ratio 1:1 or 1:3 is preferable, according to doctors and patients we’ve spoken with.
This recommendation comes from doctor and patient experience, not from clinical evidence. Although we have been unable to find any research on this, UPG is hearing from doctors, nurses, and patients that these dosages are best for treating these different types of breast cancer. We would like to hear from everyone who has
experience or knowledge about this topic, and we invite you to share your thoughts in the comments.
Do not forget to schedule your regular check-ups with your doctor.

I am in the uk and have her2 breast cancer secondary
Elaine,
We are so sorry to hear about your diagnosis. Did you have any questions?
Lauren
hello im rowel and i lived in philippines, i just want to know if you can shift the oil for my sister she is in stage 4 of breast cancer, and it is spread all over her lungs I hope that your the answer for our prayer,,,, I hope you can help us to extend the life of my sister
Rowel,
Unfortunatley it is illegal to ship out of state and to other countries. You may want to ask this question on the Facebook page called “Cannabis Oil Success Stories”. Maybe there is someone there that has contacts in your country.
Brent
Lauren…I’m in a legal state…N. Bend OR. Can you make a referral in Southwestern OR?
I have a rare Estrogen + Sarcoma of the uterus. High THC fuels growth for me. I seem to be ok with up to 44% thc. I just travelled to the US to become a medical marijuana refugee
I eventually found the info i was looking for. One needs to take a slightly higher THC dose AT NIGHT while one’s hormones are sleeping. And high cbd in the day. Hope this helps
What state did you move to? Are they giving you chemo and radation? Is the treatment working? Sorry I have so many questions I live in a state where it is not legal. I’m only 26 and have to go have a mammogram done on my breast because they found a mass through an ultrasound that they did and I am freaking out! I would like to avoid chemo and radiation because of the “risks” and opt for doing it naturally but I don’t even know if that’s possible
Catherine,
California is the easier route when it comes to becoming a legal cannabis patient. It is highly recommended to have a consultation with one of our oncology nurses in order to understand which formulation is best for your condition and what the dosages should be. This kind of guidance is hard to find as dispensaries rarely carry all formulations and are legally not alowed to give dosing instructions. If you would like to schedule a phone or skype consultation, please click here for the scheduling system.
All the best,

Please check out and research Cannabis Oil for cancer treatment. I did take two chemotherapies and it almost killed me from side-effects! There some ‘other’ alternatives out there, but you must choose and I suggest you look up results and/or testimonies regarding usage. The medical doctors (oncologists) only know One-way and the negative results (death!) outweigh the benefits.
If you are going to do chemo/rad… Research and find doctors who know about fasting protocols for a few days before chemo/radiation treatments to reduce or in come cases eliminate side-effects and increase treatment results.
I am post menopausal,taking anastrazole for triple positive breast cancer.
Please could you clarify ratio of thc to cbd, and if this ratio needs to be different at certain times of the day.
Not clear on this yet.
Thanks.
Cornelia,
We cannot recommend dosing to as that is best left to our oncology nurses and physicians. If you would like a consultation, please click here to choose a date and time. Triple positive bc is tricky and needs to be overseen by a professional.
All the best,
UPG
Hi cornelian . . Did you follow this through and get any answers on the ratio of THC to CBD?
I’m Stage 3 HER2 + and I have been taking the oil for one month and I’m not sure what the ratio was of CBD to THC but I’ll check it out thanks.
Hi Leslie,
I would really like to know if this helped you by taking the oil, my mom is stage 4 and we’re running out of options. I hope I can hear from you soon.
Kind regards,
Jane Parker
There are so many women in my life that I wish I could have shared this with. I’m going to share this article with my family as my Grandma and a few other family members have had breast cancer.
HI , my question is ,what needs to be the ratio for HER2 /neu 3% positive
Thank you in advance for your info , it is so helpful .
Chrystel,
This would be a question for a medical professional. If you would like to book an appointment with our oncology nurse, you can see her sheduling system here.

Check your cholesterol levels…People with high cholesterol intake or known high cholesterol from tests, will respond well to the cholesterol lowering acting of marijuana…Those with already low cholesterol levels will only benefit marginally from marijuana/cannabis use…The side effects of CBD oil for example can include constipation( which can hamper a detox program), lethargy( which impedes an exercise program), & memory loss( which can lead to using only the CBD oil as a tool, instead of a more multifaceted intelligent approach)…The side effect of the increased hunger, can off rail a raw plant based diet approach into a more protein, sugar or cholesterol hungry, American Standard diet…The side effects of CBD oils are not being discussed in anti cancer conversations…Using CBD oil when one is already low cholesterol can be detrimental…It is not a catch all cute as it is often touted…
Sorry several typos above, I am on an iPhone…
Not ” acting” but ‘ action’…
Not ” cute” but ‘ route’…
To add: If one has taken too much CBD oil or other marijuana based medicine, one may need to recover by antidoting…
Things like Aloe Vera juice, L- Carnitine, Maca, Cacao, Cinnamon- can replace levels that have been overly lowered by taking say CBD oil when it was not necessary…( & only in those cases)…Arnica Montana heopathic can also patch things up…
It should also be noted that CBD oil can impeded wound healing from surgery, biopsy, mammogram injury…Use with caution if injuries have not healed…
” homeopathic”, ” impede”…
I was diagnosed with triple negative breast cancer 3 years ago, given the all clear in Feb 2015, then found out it had spread to my brain, lymph nodes and lung. Would you think the same ratio of THC/CBD should be used now as with triple negative breast cancer? I’ve never used it before.
Ar,
This would be a question for our oncology nurse. She can ask you all of the medical questions to better understand what is going on in your body. Additionally, she can give you an overview of products and dosing practices that have shown positive results in women with your condition.

Where the research was conducted?
What is CBD means?
How ratios is calculated for a patient?
How the effect of this oli was measured?
Was paciwnts taking other treatments like chemotherapy?
Natalia,
CBD stands for Cannabidiol. Tatios are calculatied specific to patients by a nurse in this industry. We do have nurse practioners and oncology nurses on staff if you are interested in scheduling an appointment. I have added the links to the nurses shcedules here for your convenience.
Some patients do combine both conventional medicine with cannabinoid therapeutics. It is a choice if you would like to combined or not.
I hope this has helped,

I was diagnosed with breast cancer this spring. I had a lumpectomy and my tumor was 1.1 cm and I had clear margins. I did do Brachytherapy and just had a mammogram and no cancer. But I am worried that could spread somewhere else. I did test positive for estrogen receptors and wondering what ration would work best for me. I do have a product that one drop contains 500mg of CBD and 5Mg of THC . What do you recommend?
Jill,
We cannot give medical advice. You may want to consult with our oncology nurse to ask the question about formulations dosages. Formulations are very specific when it comes to Estrogen positive cancers. I have attached the nuses scheduling system here for your convenience.

I have stage 4 ovarian cancer. My tumor tested ER positive. Would your staff be knowledgeable for cannabis oil dosing for my condition?
Holly,
Yes, our oncology nurse is well veersed in dosing as well as the dosing and formulations for ER+ conditions. I have attached the nurses schedule here for you convenience. You will be able to choose a date and time for a phone or skype consult. If you live in the Bay area of California, face to face consults are on Mondays and Fridays.
I hope this helps,

Hello,
My mom has tripple negative breast cancer grade 4,
which kind of ratio do u recommended?
what it
Ortal,
Each patient is treated differently. This is not a one size fits all protocol. Much depends on age, weight, other medications, past treatments, other conditions, and so on. Your question cannot be easily answered. this is why getting guidance form a medical professional is imparative, especially with breast cancers.
I hope this helps! If you would like to furhter discuss, feel free to call our offices at 415-524-8099

Im waiting to hear cause for my DCIS – breast cancer, with high grade. I have ordered cannabis oil and had no idea that the thc and the cbd need to be in any particular ratio. Im not even sure the provider will be honest enough to supply me with the information!!! I understand that he normally does’good’ quality approx 70-80 pc thc. Im very happy to speak to the oncology nurse, but before I do, do I cancel the order, or can I just take more or less of the stuff, as per grading of my cancer and according to the nurse, or will this have to be a completely new order. Please help
Anita,
We cannot advise you on your current order as we do not know the formulation. It is a red flag if you cannot see the test results. All cannabis oil should have test results.

I was diagnosed breast cancer, it is progesteron positive and estrogen positive (30%) and HER2 negative, gradus 2-3. Please could you tell me the ratio between THC and CBD.
Thank you for your answer,

Hello Sasa,
Your type of breast cancer requires guidance from an oncology nurse or a physician. Each patient is different due to progression of the disease, age, height, weight, previous procedures, additional meds or supplements. It is very important that you get the correct formulations and dosages. If you could like to sign up for a consultation with an oncology nurse, please click here for the scheduling system. There is a one time fee for the hour which will help you to avoid the tangled web of this industry.
If you have any questions, feel free to call our offices at 415-524-8099.

Lauren
Hi!
I am interested in calling your group, and understand a payment is involved. Can you tell me how I can determine how much my phone consultation would cost?
I just need advice on ratios to keep my cancer from becoming active again. I have ER+/PR+ breast cancer and the article doesn’t address this type. To make matters worse, ER+ ratio is different from PR+ ratio.
Hello Cyndi,
Here is the link for a consultation. Our nurses charge $150 per hour. Please know that it is free to call our offices, it is only the consultations that have a fee for medical advice and direction.

Thanks!!!
One more question. I noticed the article doesn’t address breast cancer when a mutation in the BRCA gene exists. There are two types – BRCA1 and BRCA2. Do you have any information about successful cannabis treatments for breast cancer associated with BRCA gene mutations?
Thanks for all the information you publish!!
Cyndi
Cyndi,
Our nurse practitioner is well versed in this area. You should also tak a look at Dr. V’s page. She is a breast cancer expert and a collegue of ours. Here is Dr.V’s website.

Thank you!
I have Invasive ductal carcinoma…triple positive. I had a lumoectomy with sentinel node biopsy. My margins were clear…tumor size just under 2cm….during surgery when they checked my nodes they were clear but after pathology tested further they found a few specks of tiny cancer cells during the staining. Now its been almost 5 weeks since surgery …I have an appt this next week to see an oncologist ….I am not happy to do radiation and chemo is a no for me . I have applied to get my marijuana medical card. I was planning on using cbd oil to help….has anyone just used the oil and not radiation and had positive results. I have also changed my diet to foods that are cancer fighting non estrocenic food….plus I have been taking…reservatrol, grape seed extract…vitamin e…and d….B complex …..and astragalus. I have o negative blood type and any of the treatments that put me at risk for bone or blood cancers scare me. Any suggestions. I am 44 will be 45 this year.
Pamela,
We always suggest a consultation with one of our nurses. We have oncology nurses and nurse practitioners on staff to assess what is best for you and your conditon. Cannabis is not a one size fits all protocol. A consultation will cover a full assessment of your current condition and what is the best formulation and dosing for you. All of your current medications and supplements will be weighed in to this consultation.
I have added the scheduling link here for your convenience.

I would like to know how many cases were involved, and how many variations.
I was ER/PR+, Her2Neu- on the left and Her2Neu positive, ER/PR negative on the right. I took mass amounts of cannabis oil for 5 1/2 weeks before my double mastectomy or any chemo. I physically shrank my masses. Going from a Stage 2, possible 3 to a Stage 1 diagnosis. I take cannabis oil every day instead of any Tamoxifen, Arimidex, or any other aromatase inhibitors. May 5th will be my two year cancerversary. I have had clean brain scans, chest x-rays, and MRIs thus far. I maintain a healthy diet. I would like to know what implied that the oil increased the mass size if you would share? Was the patient consistantly taking oil? Perhaps they needed higher quantities? Just wondering. I had wonderful results with both ER/PR+ and Her2Neu+, bi-laterally. I continue to take both high CBD and THC oils. Thank you. Dawn Ann
Hello Dawn,
Much of the reports comes from various physicians and nurses who are treating these patients. It is wonderful that you are having such positive results. Yes, their diets, consistancy and dosing is so important and at this point ther is not enough clinical research to have conclusive evidence to whos cancer was speread by which oil, dosing schedue or diet. We with there was!

Science indicates that every cancer and every patient is different. However, all cancers and all living things require fuel to maintain the living state. Drug sensitive cancers typically burn carbohydrates, whereas drug-resistant cancers typically burn fats. Sugar burning cancers are therefore easier to kill because apoptosis is more readily induced. Theoretically based on my understanding of life, in order to kill cannabis-resistant cancers a pro oxidants must be added to the treatment regiment (for example,intravenous high-dose vitamin C, or intravenous insulin therapy).
Why has the recommendation for TNBC changed (again)? It was high thc to cbs, then high cbd to thc and now back again?
What gives? Have you found out further information on the absorption of cannabis oil rectally and vaginally? It seems for virtually all canfers, oral is the best dosing route for absorbtion of cannabis oil.
Thank you.
Dana,
It seems that researchers and physicians are finding varying results. This is a critical area that needs funding for extensive research.

I had a lumpectomy five years ago and did 6 weeks of radiation… but the cancer has returned. I now have stage four breast cancer that has metastasized to the lung and bones. There was also a tumor in my eye but that one has totally disappeared after 6 injections of Avastin directly into the eye mass. My cancer is HER2 neu negative, ER PR positive. I am currently taking Letrosol and Ibrance.
I want to try the cannabis treatments and was ready to buy some Indigo and try to make the oil myself according to the instructions of cannabis cure pioneer Rick Simpson. But after reading this blog, I am confused as to the ratio of THC oil to CBD oil and where to find tested oils. I am bi-coastal living part time in LA but mainly in NYC. I remember reading that the Cuomo administration demanded that the THC be removed from the marijuana products. But can you help me with the correct dosage and protocols regarding my exact diagnosis?
JR,
Thank you for your inquiry. We highly suggest making a consultation appointment with one of our oncology nurses. Breast cancer is treated very specifically and a high THC regime/high dosage, such as the protocol you mentioned, may not be the correct approach for BC. Many beloeve that high dosages, in some cases, can be counter productive. If you are intersted in making a consultation appointment, please click here.
If you prefer not to seek medical guidance then please proceed with caution.
Wishing you well.
Lisa
could I please get a recommendation for breast cancer diagnosis with herceptin positiv, estrogen negativ and G3?
Aminah,
In order to understand the best formulationand dosing for your condition you must speak with a medical professional. This is not a one size fits all and your medical history, current medicationa sn and supplements combined with any other health issues all play a part in honing in on the best protocol for you,
It is a red flag if you are guided by someone who knows nothing about your medical history and medications.
I Hope this helps!

@drbob Melamede ”Drug sensitive cancers typically burn carbohydrates, whereas drug-resistant cancers typically burn fats.”
Most cancer cells are unable to do this as they have abnormalities in the genes and enzymes needed to metabolize ketone bodies for energy, they need glucose and glutamine http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3941741/
Brent. – I received a recommendation letter from a medical doctor who provides recommendations. She informed me , however, that she is prohibited from giving “dosing advice” of any kind, including discussing potential drug interactions. I am perplexed. I was required to bring health records and a list of all medications – and if this doctor cannot help guide me on dosing , who can? Why would your nurses be able to help with this information and this doctor cannot? Since I already paid for my time with one doctor , I would be reluctant to have to pay another doctor for more information. Just trying to understand all the resources I will need in this process and what monies I should expect to pay.
Thanks,
Confused in LA
MV,
Many physicians are afraid of losing their licenses. From what we have heard, physicians are worried that they will get in trouble for “Aiding and Abedding” of a controlled substances. Most of these docotors work within a group or institution. These insitutions must follow federal law.
Our nurses are in private practice. They are working in a cannabis legal state with legal patients. Within California they are able to give dosing instructions as well as drug interaction guidance.
This is one of the many grey areas of this industry. Hopefully, it will become more streamline and accurate with the state regulations coming.
