It is still unclear whether using cannabis has any anti-cancer effects. But there is some evidence that the chemicals in cannabis might help with symptoms such as nausea and pain.
But these studies have had mixed results when used in clinical trials. Because of the mixed results, the general feeling of experts is that there needs to be more research into the chemicals found in cannabis and their possible benefit. Cannabis, particularly cannabis oil, is a popular topic. Cannabis oil is only one of a number of treatments people might come across. It can be sold in the UK as long as it is sold as a food supplement and the sellers are not making any claim about its medicinal properties.
There are a number of examples where people say that using CBD oil has had a dramatic effect on their health. But these are individual stories and not based on clinical research trials. If you are thinking of using CBD oil, we suggest you talk to your healthcare team. If you are looking for information online you want to be sure that it is accurate and up to date.

Some people find complementary therapies lift their spirits and help them relax and cope with stress. Surgery is the main treatment for brain tumours. But some tumours cannot be removed because they are too difficult to reach, or the risk of damaging the brain is too high. We want to make sure we're there when you're diagnosed, through treatment, and beyond.

Cannabis oil and cancer. Two main cannabinoids have been identified: Additionally , in vivo studies in thymic aplastic nude mice revealed a significant inhibition of A lung metastases following CBD treatment [ 51 ] and a significant downregulation of PAI-1 protein was demonstrated in A xenografts of CBD-treated rats [ 52 ]. It is worth noting that CBD decreased invasiveness in a range of therapeutically relevant concentrations 0. Together, these findings provide a novel mechanism underlying the anti-invasive action of CBD on human lung cancer cells and imply its use as a therapeutic option for the treatment of highly invasive cancers.
Thyroid cancer is the most common endocrine malignancy and Ligresti et al. Later on, Lee et al. The presence of N-acetyl-L-cysteine NAC , a precursor of glutathione, markedly attenuated the induction of apoptosis and restored the diminished levels of cellular thiols. The observation that CBD induced oxidative stress in thymocytes, EL-4 cells and splenocytes [ 56 ] substantiates the notion that, unlike monocytes, T cells both primary and immortalized, are all sensitive and respond similarly to CBD, with a central role of ROS generation.
Colon cancer is a major cause of morbidity and mortality in Western countries. A recent paper from Izzo's group [ 57 ] demonstrated the chemopreventive effect of CBD in a preclinical animal model of colon cancer based on azoxymethane AOM administration in mice.
In vitro studies, supported the beneficial effect of CBD. In the light of its safety records, these results suggest that CBD might be worthy of clinical consideration in colon cancer prevention.
Angiogenesis consists of the formation of new blood vessels from pre-existing ones and represents another promising therapeutic target for cancer therapy. Surprisingly, so far no study has investigated the effect of CBD on angiogenesis.
Our data currently awaiting publication [ 58 ] demonstrated that CBD potently inhibited HUVE cells proliferation, migration and invasion through the induction of endothelial cell cytostasis without triggering apoptosis. Interestingly, CBD also affected endothelial cell differentiation into tubular capillaries as well as the outgrowth of capillary-like structures from HUVEC spheroids in vitro. In addition, the anti-angiogenic properties of CBD were demonstrated also in vivo , using a matrigel sponge model.
Collectively , these preliminary data demonstrate that, besides its well known pro-apoptotic anti-proliferative and anti-invasive actions, CBD may also exert anti-angiogenic effects, thus further strengthening its potential application in cancer therapy. Collectively, the non-psychoactive plant-derived cannabinoid CBD exhibits pro-apoptotic and anti-proliferative actions in different types of tumours and may also exert anti-migratory, anti-invasive, anti-metastatic and perhaps anti-angiogenic properties.
On the basis of these results, evidence is emerging to suggest that CBD is a potent inhibitor of both cancer growth and spread. Interestingly , the anticancer effect of this compound seems to be selective for cancer cells, at least in vitro , since it does not affect normal cell lines. The efficacy of CBD is linked to its ability to target multiple cellular pathways that control tumourigenesis through the modulation of different intracellular signalling depending on the cancer type considered.
The most common effect of CBD is the increase in ROS production that seems to be determinant for triggering its beneficial action in all the considered cancer cell types. In some cases lung, leukaemia, colon a clear contribution of these receptors has been demonstrated through the use of specific antagonists, but in other cancer types glioma and breast their relevance appears only marginal or absent.
Besides the in vitro data, the efficacy of CBD in reducing tumour growth and, in some cases, metastasization was confirmed in experimental animal models. However, the potential clinical application of CBD for cancer therapy needs some consideration. Its low toxicity is certainly a good starting point. The route of administration appears more problematic since CBD oral absorption is slow and unpredictable. Interestingly, this range of concentration was demonstrated to be active in inhibiting lung cancer cell invasion [ 52 , 53 ], thus suggesting that in some cases the oral route could be the appropriate choice.
Moreover, oromucosal administration may represent a first choice in the presence of nausea and vomiting. In the light of its safety record and considering that CBD is already currently used in patients with multiple sclerosis, the findings here summarized suggest that CBD might be worthy of clinical consideration for cancer therapy.

CBD and breast cancer In Ligresti et al. CBD and glioma CBD also possesses anti-tumoural properties in gliomas, tumours of glial origin characterized by a high morphological and genetic heterogeneity and considered one of the most devastating neoplasms, showing high proliferative rate, aggressive invasiveness and insensitivity to radio- and chemotherapy.
CBD and lung cancer Given the poor response of lung cancer to available therapy and its aggressive biological nature, a series of targets and new therapeutic strategies for their treatment are currently being investigated [ 47 — 50 ].
