The claim that a common household ingredient like sodium bicarbonate, or baking soda, can treat cancer is a pervasive and dangerous myth circulating on the internet. Often promoted as a simple, miraculous alternative to conventional medical treatments, this theory lacks any scientific validation. In fact, medical authorities and scientific evidence confirm that not only is this “remedy” ineffective against cancer, but it can also cause severe, life-threatening harm and accelerate a patient’s decline by delaying legitimate medical care.
⚠️ WARNING – Risk of Fatal Metabolic Alkalosis and Organ Failure!
Self-administering high doses of sodium bicarbonate, especially via injection or infusion, is extremely dangerous. It can overwhelm the body’s tightly regulated pH balance, leading to a severe condition called metabolic alkalosis. This can cause cardiac arrhythmias, seizures, kidney failure, and death. This practice must be avoided under all circumstances. Always consult a qualified oncologist for cancer treatment.
Baking Soda and Lemon Juice for Cancer – A Dangerous Myth
The Origin of a Discredited Theory
This dangerous hypothesis was popularized by a former Italian doctor, Tullio Simoncini, who had his medical license revoked. He claimed, without evidence, that all forms of cancer are caused by a common fungus, Candida albicans. Consequently, he proposed that cancer could be “washed away” using sodium bicarbonate, an antifungal agent. This simplistic and appealing idea quickly gained traction online, offering false hope to vulnerable patients.
Despite the complete absence of credible studies, this unproven treatment is promoted as an effective alternative to evidence-based oncology, such as chemotherapy. However, medical authorities in the United States, the Netherlands, and worldwide warn that the effects of self-prescribed sodium bicarbonate on a cancer patient can be devastating.
Legal Consequences and Patient Harm
The dangers of this practice are not merely theoretical. In 2006, Tullio Simoncini was convicted by an Italian court for wrongful death and fraud after a patient died following his “treatment.” Subsequently, a serious investigation began in the Netherlands in 2007 after a 50-year-old woman with breast cancer died in a hospital in Amsterdam. It was discovered she had been receiving sodium bicarbonate injections and infusions at a clinic associated with Simoncini.
Following this tragedy, the Dutch Health Inspectorate issued a public warning, stating that sodium bicarbonate infusions are dangerous, ineffective, and pose a direct threat to vulnerable patients. They found a direct link between the woman’s death and the bicarbonate administration. Despite these convictions and warnings, Simoncini and others have continued to promote these claims online, often for significant financial gain.
Specific Biological Limitation
Disruption of Systemic pH and Metabolic Alkalosis
The human body maintains blood pH within a very narrow, slightly alkaline range (7.35 to 7.45) through complex buffering systems in the blood, lungs, and kidneys. Introducing large amounts of an alkaline substance like sodium bicarbonate overwhelms these regulatory mechanisms. This action does not selectively target tumors but instead causes a systemic and life-threatening imbalance known as metabolic alkalosis.
Technical Warning: Metabolic alkalosis leads to severe electrolyte disturbances, particularly low potassium (hypokalemia) and calcium (hypocalcemia). These imbalances can trigger severe cardiac arrhythmias, muscle spasms, seizures, and respiratory depression. Furthermore, the kidneys are put under extreme stress as they attempt to excrete the excess bicarbonate, which can lead to acute kidney injury, especially in patients already compromised by cancer or its treatments.
Administration Protocol and Safety Limits
Warning Against All Forms of Self-Administration
There is no medically approved protocol for using sodium bicarbonate as a cancer treatment. The methods promoted online are not based on clinical research and pose extreme risks. This section serves as a warning against attempting any such protocol.
-
- Treatment Duration: There is NO safe duration for this unproven and dangerous practice. Any use delays effective medical treatment, allowing the cancer to progress.
- Maximum Daily Dose: There is NO safe dose of sodium bicarbonate for treating cancer. The quantities required to theoretically alter a tumor’s local pH would be systemically lethal, causing severe metabolic alkalosis long before any potential therapeutic effect could be achieved.
- Administration Condition:
- Oral: Ingesting large amounts can cause severe gastrointestinal distress, gas, bloating, and electrolyte imbalances.
- Intravenous (IV): Administering sodium bicarbonate intravenously outside of a controlled, intensive care setting is exceptionally dangerous and can be immediately fatal. It should only be done by medical professionals to correct severe metabolic acidosis, not as a cancer therapy.
Contraindications and Precautions
Absolute Prohibition for Cancer Patients
The use of high-dose sodium bicarbonate is absolutely contraindicated for any individual outside of a hospital setting for a diagnosed condition like acidosis. The risks are magnified in cancer patients.
-
- Absolute Contraindications: Forbidden for individuals with cancer, kidney disease, heart failure, high blood pressure (hypertension), or liver disease. The sodium load can worsen fluid retention and hypertension, while compromised organs cannot handle the severe pH and electrolyte shifts.
- Vulnerable Populations: This practice is dangerous for everyone. It is particularly life-threatening for the elderly and patients weakened by cancer (cachexia), whose bodies have diminished physiological reserves.
- Major Drug Interactions: Sodium bicarbonate alters stomach and urinary pH, which can dramatically affect the absorption and excretion of numerous medications, including certain chemotherapy agents, antibiotics, and heart medications.
- Documented Adverse Effects: Nausea, vomiting, headache, dizziness, muscle spasms (tetany), irritability, cardiac arrhythmias, seizures, respiratory depression, kidney failure, and death.
- When to Seek Emergency Care: Stop immediately and seek emergency medical help if any symptoms like muscle twitching, confusion, irregular heartbeat, or difficulty breathing occur after ingestion.
Therapeutic Alternatives
Evidence-Based Cancer Care
If you or a loved one is facing a cancer diagnosis, it is critical to rely on scientifically validated treatments. Disinformation can be deadly, as it encourages patients to abandon therapies that could save or prolong their lives.
Validated Medical Treatments
The only proven treatments for cancer are provided through conventional oncology. These are rigorously tested for safety and efficacy. They include:
-
- Surgery
- Radiation Therapy
- Chemotherapy
- Immunotherapy
- Targeted Therapy
- Hormone Therapy
Consulting with a board-certified oncologist is the only responsible first step after a diagnosis.
Supportive Botanical and Integrative Therapies
Important: No herb or supplement can cure cancer. However, some may help manage the side effects of conventional treatment and improve quality of life when used under the guidance of an oncologist.
-
- Ginger (Zingiber officinale): Strong evidence supports its use for managing chemotherapy-induced nausea.
- Turmeric (Curcuma longa): Its active compound, curcumin, has well-documented anti-inflammatory properties. Research is ongoing, but it should not be used without a doctor’s approval as it can interact with medications.
Note: Always discuss any supplements or herbal products with your oncology team, as they can have significant interactions with cancer treatments.
Recent Medical Research (2020-2026)
Distinguishing Legitimate Science from Pseudoscience
Modern cancer research does investigate the tumor microenvironment, including its acidic pH. Some cutting-edge, experimental studies explore ways to modify this environment to make chemotherapy or immunotherapy more effective. For instance, a 2022 study in Nature Communications explored using nanoparticles to deliver bicarbonate to tumors in mice to enhance immunotherapy.
Crucial Distinction: This highly complex, targeted research has absolutely no connection to the simplistic and dangerous act of drinking or injecting baking soda. These studies use advanced delivery systems to target the tumor directly without causing systemic metabolic alkalosis. The “baking soda cure” myth dangerously misinterprets this legitimate science.
The overwhelming scientific and medical consensus remains that the Simoncini protocol is baseless, fraudulent, and harmful.

Specialist’s Summary
The theory that sodium bicarbonate can treat cancer is a disproven and dangerous myth originating from the fraudulent claims of a disgraced former doctor. This practice does not cure cancer; instead, it causes a potentially fatal condition called metabolic alkalosis by disrupting the body’s essential pH balance. Pursuing this “remedy” leads to harmful delays in receiving legitimate, evidence-based medical care. The only responsible course of action for a cancer diagnosis is to consult a qualified oncologist and follow established medical protocols.
Frequently Asked Questions
Can baking soda and lemon juice cure cancer?
No. There is absolutely no scientific evidence to support this claim. It is a dangerous myth that can lead to severe health complications, including death, and prevents patients from receiving effective medical treatments.
What are the real risks of trying the baking soda cancer treatment?
The primary risks are severe metabolic alkalosis, which disrupts bodily functions and can cause cardiac arrest or seizures; acute kidney injury; and dangerous delays in starting proven cancer therapies, which allows the disease to progress unchecked.
Why is the “cancer is a fungus” theory incorrect?
Decades of research have definitively shown that cancer is a genetic disease caused by uncontrolled cell division, not a fungal infection. Biopsies of tumors do not show fungal colonies. This foundational claim of the baking soda myth is biologically false.
Are there any valid natural treatments that can cure cancer?
No. No diet, supplement, or herbal remedy has been proven to cure cancer. Some integrative therapies can help manage symptoms and improve quality of life when used alongside conventional treatments, but they must always be discussed with and approved by an oncologist.

Well, chemo certainly does NOT cure cancer, that is just a total money making racket for doctors!! It has a 3% cure rate!!!! The body is not meant to be pumped full of poisons that kill the immune system, how on earth can your body fight disease and recover without an immune system?? Keeping the body in an alkaline state is a way to control cancer, an acidic system (caused by the rubbish in foods) is what causes cancer! So treat the cause and not the symptom!!”
OMG!!! Chemo does not cure cancer? Really!? Please tell that to all parents to children who have survived leukemia. 40 years ago, when there were no effective chemotherapies, 10 out of 10 kids died. Today 9 out of 10 survive. Tell me again that chemo does not cure cancer.
I totally agree
Now who on earth believes this nonsense? IF it was true, all cancer research would be stopped and lemon trees would be planted in masses. Then it’s kiwi fruit, then it’s strawberries, always some kind of natural ingredient that “cures” cancer. Show me the scientific proof done at a reputable university, then I will believe it. Please don’t let terminally ill or any cancer patients do this, they need expert help. This article states that this is so not true…
No one is asking you to believe something outrageous. If you knew what a sham the pharmaceutical industry and for that matter the entire medical industrial complex is, you wouldn’t find this so strange. People who declares, like Marietjie Mare does, “cancer research would be stopped and lemon trees would be planted in masses.” are obviously still stuck in the mindset that “mainstream medicine would NEVER lie to me!” wakey wakey Marietjie! (no one get’s rich from healthy patients and if you do your homework you’ll find out that every successful cure for cancer has been suppressed so far and the doctors that developed them, persecuted insanely!) People are so gullible, honestly!
Very true Ulanda.The cancer industry wants customers not cures
Lemon is not a cure but Chemo cure you? I want to hear what this so call “scientists” talk about Chemo.
Yep, quiet and endorsed it as cure. I say go to hell with the scientists and urge them to work for science not money.
This article does not cite ANY scientific studies… But this one does…

Interesting…
Maybe if the one saying chemo (adding more toxins to your body) is a better idea than using something that is picked off a tree (lemons) had some kind of study to reference to back up their claims, this would be a relevant article.
Since there’s not, maybe it was written by someone paid by a drug company… Maybe not.. You decide.
I live in the UK where medical treatment is free and it is costing the NHS billions of pounds a year.
My question is if there is such a cheap alternative to cure cancer then why is it not being used thus saving the national health service millions of pounds in expensive chemo drugs.
I would like to believe that this is a miracle cure but I am a little sceptical.
Richard, you’re still living in la-la land. Wake Up.
The ultra rich and upper class have had a death grip on the medical industry, ‘news’ outlets and western governments for that matter for, well, the beginning of civilization buddy. Its a simple sham. Global corporations develop food full of harmful unnatural chemicals (preservatives, coloring, texturing, flavoring chemicals). They lobby the governments and educational institutions to avoid nutritional programs for doctors, and the pharmaceutical companies literally write the rules and academia of doctorate programs and teach how to administer drugs and perform operations. They teach doctors in depth about the body and it’s interaction with disease. They do not teach HEALTH. Therefore, you have an uninformed public eating complete garbage, getting sick, and going to the hospitals for TREATMENT not cure. And the doctors have absolutely little clue about the role nutrition plays on the body. The science is now coming out in masse from the studies being done in educational institutions around the world, and it will not hit the doctors hands because doctors are bound by the industries that keep disease going.
Thanks to all this and many other things going on in society, the rich get richer, the poor get poorer and sicker, the economy slags behind, and people are drugged up and malleable subjects.
Eugenics is the proper descriptor.
You’re welcome for the debriefing about the reality of the planet you live on.
Go to the’ Truth about Cancer’ website…these guys are dispelling the ‘quackery’ and absurdness around the current medical establishments treatment in the bucket loads…They surveyed a lot of Oncologists and 82% said they wouldn’t put chemotherapy into their own bodies, and definitely not into their children’s or spouses. It’s far too toxic. On every bag of Chemo is the warning ” This causes cancer’…unbelievable..so does radiation and surgery to some degree, increases the spread of the disease. The medical establishment has some serious ‘waking-up’ to do but because it is a multi billion dollar business and many people are very reliant on the jobs it provides…progress won’t be very fast.
So many things can help, including meditation and facing one’s issues.
Its for each person to decide for or against invasive treatments. Who knows, maybe some dose of the ‘bad’ substance wakes the body into action and makes the person take their life to the fullest potential.
Let’s look at this from a logical point of view. I’m not saying which side is accurate because I’m not a molecular scientist. But I do know this: fact – cancer cells cannot survive in an oxygenated state. Raising the body’s alkaline above 7.3 will in fact put your body in an oxygenated state. I personally raised my body’s alkaline from 5.5 to 7.0 in only 6 hours by drinking one 6 ounce glass of water with a 1/2 teaspoon of baking soda. I did this because I wanted to test the waters myself before telling my sister (and possibly getting her hopes up) who has stage 4 appendiceal cancer and 5 bouts of CHEMO have proven futile. I encourage anyone interested to try it – but first make sure with your doctor that you do not have any particular illness that could possibly be harmed by raising your alkalinity. I assure you it will indeed raise your body’s alkalinity.
You can decipher this for yourself. Question – why are there no real studies proving this concoction to be true? Common sense says because there is no pharmaceutical company in the world who is going to fund a study that could potentially KILL their MONSTER stream of income. And there is no government on earth that is going to fund a study that if proven to be true will put many countries into a terrible financial tailspin creating the worst recession in history. CANCER is BIG, BIG, BIG business. THIS FACT CANNOT BE DENIED!!!
Also, think about what happened with Simoncini. Hundreds of people testify that he helped them rid themselves of the disease and only 1 person died using his treatment for which he was prosecuted. Now ask yourself, how many oncologists have been prosecuted when people die from their CHEMO cocktails? Why is that? Studies indicate the average cancer chemo treatment in the U.S. runs in the neighborhood of $250,000. The average glass of lemon water with sodium bicarbonate runs less than $1.
You be the judge.
The cancer research industry has a vested interest in not finding treatments for cancer that are cheap and widely available – that is why there is no research on effects of acidosis and lemon/bicarb’s effect on this, cannabis treatments, herbal or even dietary treatments. Industry is about making money and this is the prime motivation for research.
