Related to this is the ketogenic diet for cancer, or the suggestion that cutting out carbohydrates can throttle glucose production and starve cancers. In fact, some advocates have even asserted that ketogenic diets eliminate the need for chemo and radiotherapy.
This understandably sounds attractive, but there is no evidence for this claim. The bottom line is that while good nutrition is important in cancer and indeed to health in general , the reality is that no diet can cure cancer — no matter how glossy the pictures might look in a diet book or on Pinterest. The hope is that cannabis, homeopathy or a herbal supplement will eradicate cancer whilst sparing the patient the potentially unpleasant treatment effects of chemo and radiotherapy.
This is not surprising as cannabis has been used recreationally and medicinally for centuries. THC in cannabis has known anti-emetic properties , and for decades agents derived from it have been used in the clinical management of pain and nausea. Beyond this, however, claims that cannabis has any efficacy as a cancer treatment are unsupported by evidence, as a wide-ranging US study recently concluded.
Cannabis may not have an impact on cancer, but at least THC has some helpful effects. Homeopathy , however, is a different story. In multiple studies , homeopathy has been shown to have no effect beyond placebo. In fact, its central tenets are completely at odds with known physics and are demonstrably wrong. Yet homeopathy remains popular. While the preparations might be in themselves biologically inert , there is a serious danger that patients will cling to the false hope offered by them and reject medical intervention that could be beneficial, which can have fatal consequences.
There are certain things we do know contribute to cancer. Yet cancer often arises in individuals with no obvious risk factors, giving it a seemingly capricious nature and leaving people struggling to find an explanation. In lieu of a clear villain, suspicion can turn on all manner of common household chemicals. Deodorants, for example, are frequently an object of concern, given their proximity to sensitive areas of our skin.
In particular, the idea that antiperspirants might cause breast cancer gained traction throughout the s. Alarming as such rumours are, numerous studies have shown this supposed link to be entirely fictitious. Artificial sweeteners too have a long history of being the target of dubious claims. Over a decade later, such rumours persist — sustained pressure by activists in even led Pepsi to remove aspartame from its products — a decision quietly reversed in Inevitably, it was only a matter of time before a link to cancer was alleged.
However, numerous studies on sweeteners including saccharin, aspartame, acesulfame potassium, sucralose and neotame show no evidence of such a link. The finger of blame is often pointed in the direction of powerlines, microwave ovens and cell phones. The microwave energy at which most domestic appliances operate completely lacks the ability to ionize DNA and damage cells, a fact confirmed by years of experiments and observations.
Readers of my original article on cancer myths might notice this one was tackled there too, but the repetition here is not accidental. The idea that big pharmaceutical companies are secretly suppressing a cure for cancer is a zombie myth, refusing to die no matter how many times it is killed by the sheer force of evidence against it.
Firstly, cancer is not a single monolithic entity, but rather an entire family of diseases with wildly differing characteristics. Even if such a cure did exist, it seems highly unlikely that if profit is the motive that pharmaceutical companies would sit on such a goldmine rather than exploit it.
CB1 receptors have been noticed in the T lymphocytes and it is proposed that their activation may be connected with the cytokine biasing induced by cannabinoids The highest level of CB2 expression has been observed in B cells, followed by NK cells, monocytes, polymorphonuclear neutrophils, and T cells It has been shown that the expression level of CB2 correlates with the cell activation state and with the presence of immune modulators The immune system is postulated to be involved in the control of growth and development of many types of cancer.
One of the key regulators of the antitumor immune response is cytokines profile. It is postulated that a Th1 response is crucial for an effective immune response against many tumors Phytocannabinoids with high affinity for CB2 receptors, such as THC, exhibit modulatory effects on both cellular and humoral immunity.
Nonpsychotropic cannabinoids with low affinity for CB receptors have also been proven to exhibit immunomodulatory action. Most of the studies indicate that cannabinoids exhibit immunosuppressive action The most extensively examined immunomodulatory effects of cannabinoids in context of cancer are regarding the changes in the activity of T cells.
It has also been proposed that cannabinoids can affect T cells by the induction of apoptosis 73 , Another possibility is that cannabinoids effects on immune cells are at least partially induced indirectly via other suppressive mechanisms such as release of cortisone The effects on the Th17 cells subsets have not been fully described to date.
Interestingly, CB receptors seem to take part in the modulation of those phenomena Indeed, there are reports indicating the suppression of anticancer immune response by THC. It has been demonstrated that THC suppresses host immune reactivity against cancer in murine lung cancer model Lewis lung carcinoma, 3LL and line 1 alveolar cell carcinoma L1C2 , leading to the increase in the tumor growth CB2 receptors antagonists also blocked the effects of THC administration.
Similar results were obtained in the study of mouse mammary carcinoma. It has been demonstrated that THC exposure leads to the significant increase in the 4T1 carcinoma growth and metastasis due to the inhibition of the specific antitumor immune response Observed effects were mediated by CB2 receptors It is possible that tumors originating from tissues of low CB receptors expression would be significantly less sensitive to cannabinoids anticancer action and, eventually, due to THC immunosuppressive properties, such tumors may find a favorable environment for growth and development.
It is also possible that anticancer properties of cannabinoids may be compensated by their immunosuppressive action, finally leading to promotion of the tumor growth. Chronic inflammation has been associated with the development of neoplasia; therefore, reducing inflammation may, to some extent, contribute to the prevention of carcinogenesis. Viability of noncancerous cells seems to remain unchanged or sometimes even elevated by cannabinoids 34 , 35 , 36 , 39 , On the other hand, cannabinoids can trigger apoptotic cell death in some types of nontransformed cells, especially those of high proliferative properties such as endothelial cells The cellular response to cannabinoids relies on different mechanisms in cancerous and noncancerous cells.
It has been demonstrated in vitro that cannabinoids can exhibit a stimulatory activity in nanomolar concentration and an inhibitory activity in micromolar concentration biphasic response , which significantly exceeds concentrations usually detected in blood of marijuana smokers Concentration of THC used in described experiment corresponded to its serum concentration obtained by smoking or oral administration of THC Besides the above described proapoptotic effect in cancer cells, cannabinoids exhibit some other important and potentially valuable properties.
It has been demonstrated that they can inhibit angiogenesis by blocking an activation of the vascular endothelial growth factor VEGF pathway. Cannabinoids have also been shown to reduce spontaneous and induced metastases in animal models and to inhibit an invasiveness of cancer cells in vitro breast, lung, cervical cancer, and glioma 86 , 87 , 88 , 89 , These effects are partially connected with a modulation of the activity of extracellular proteases and their inhibitors 86 , The pharmacological inhibition of ceramide biosynthesis and the expression of p8 protein lead to the prevention of the mentioned effects The studies conducted to date indicate that antiangiogenic and antimetastatic characteristics of CB receptor agonists, similar to their antiproliferative effects, rely on the stimulation of ceramide biosynthesis and a modulation of pathways involving p8 protein.
Cannabinoids that are not agonists of CB receptors CBD , have also been shown to exhibit such properties. Increased levels of FAAH substrates e.
Data collected to date regarding anticancer effects of cannabinoids are almost completely limited to preclinical studies conducted on cell lines and animal models. The first experiment that was conducted on human subjects was a pilot clinical study on nine terminal patients with recurrent glioblastoma who were resistant to the standard therapy Patients received THC intratumorally.
This way of administration was safe and patients did not exhibit any overt psychoactive effects. In some patients the tumor growth rate decreased. Changes observed upon THC administration in two patients can be connected with anticancer effect of THC according to previous preclinical studies decreased cell proliferation, occurrence of apoptosis Despite these interesting observations, it is not possible to draw significant conclusions from the study on a group of nine.
This shows a need for further clinical trials, which could help to assess the dosage and the potential interaction of cannabinoids with other substances. These studies are currently ongoing or have ended recently, but the results have not been published to date. Cannabis plants produce a substantial amount of cannabinoids and other secondary metabolites. It has been demonstrated that extracts of Cannabis exhibit stronger effects on the subjects with spasticity than pure THC Some cannabinoids have been demonstrated to attenuate psychoactive effects of THC or smoked marijuana 13 , Pure cannabinoids are more convenient for study and to a subsequent standardization as a medical preparation, but still Cannabis extracts with specified amounts of cannabinoids seem to be valuable aim for further studies, also as potential anticancer agents.
An interesting idea is a combination of cannabinoids with conventional anticancer drugs, which can exhibit synergistic potential. The promising results from studies on animal models of glioblastoma treated with THC and temozolomide have led to, mentioned above, clinical trial of this chemotherapeutic agent and Sativex 94 , Similar observations from the study on pancreatic adenocarcinoma showed that gemcitabine administered with cannabinoids synergistically inhibited cancer cell growth To date, Cannabis or its preparations have found an application in a palliative medicine due to its analgesic and antiemetic effects, an attenuation of the side effects of chemotherapy or a capacity to treat spasticity in multiple sclerosis.
We are still initial stages of incorporating Cannabis products in the clinical care. There is still a lack of profound safety and efficacy clinical trials and it is very difficult or even impossible to assess the potential benefits and risk of using cannabinoids in many cases.
Many aspects wait for an elucidation: The most common way of using recreational marijuana is smoking, which is unsuitable way of an administration from a medical point of view. Another important issue is the lack of easy accessible biomarkers showing the responsiveness of patients to a cannabinoid treatment.
Moreover, antitumor effects of cannabinoids have to overcome their known immunosuppressive effects which can be potentially protumorigenic. The interactions between cannabinoids and classical cytotoxic agents have to be precisely defined.
These observations lead us to the conclusion, that further profound studies are doubtlessly needed to verify the idea of introducing cannabinoids into the cancer treatment.

Abstract To date, cannabinoids have been allowed in the palliative medicine due to their analgesic and antiemetic effects, but increasing number of preclinical studies indicates their anticancer properties. Introduction Nowadays, we observe an increasing public and scientific interest in the medical applications of Cannabis plants.
Endocannabinoid system and cancer Despite numerous studies conducted during the last decade, there are still inconsistent data regarding the exact role of cannabinoid system in cancer development.
