Mounting evidence shows 'cannabinoids' in marijuana slow cancer growth, inhibit formation of new blood cells that feed a tumor, and help manage pain, fatigue. The two best studied components are the chemicals delta tetrahydrocannabinol (often referred to as THC), and cannabidiol (CBD). Cannabinoids are the components in cannabis; some are commercially available to treat symptoms. Get detailed information in this clinician.

Most of these compounds will never make it into the clinic to treat patients for a huge range of reasons including toxicity, lack of effectiveness, unacceptable side effects, or difficulty of delivering the drug to tumours.
If cannabinoids are ever to get into clinical use, they need to overcome these hurdles and prove they have benefits over existing cancer treatments. But can they stop the disease from developing? Or could they play a role in causing cancer? In experiments with mice, animals given very high doses of purified THC seemed to have a lower risk of developing cancer, and there has been some research suggesting that endocannabinoids cannabinoids produced by the body can suppress tumour growth.
This is mainly because most people who use cannabis smoke it mixed with tobacco, a substance that definitely does cause cancer. In some parts of the world — including the Netherlands — medical use of marijuana has been legalised for palliative use relieving pain and symptoms , including cancer pain. But one of the problems of using herbal cannabis is about dosage — smoking it or taking it in the form of tea often provides a variable dose, which may make it difficult for patients to monitor their intake.
So researchers are turning to alternative dosing methods, such as mouth sprays, which deliver a reliable and regulated dose. We want to see safe, reliable and effective treatments become available for patients as quickly as possible. We receive no government funding for our research, and it is all paid for by the generosity of the public. This is obviously not a bottomless purse, and we do not have financial reserves to draw on.
Because of this limitation, we can only fund the very best research proposals that come to us that will bring benefits to people with cancer. Our funding committees have previously received other applications from researchers who want to investigate cannabinoids that have failed to reach our high standards for funding. If we receive future proposals that do meet these stringent requirements, then there is no reason why they would not be funded — assuming we have the money available to do so.
But whole plants or other organisms are a complex mix of hundreds of chemicals not all of which may be beneficial and contains low or variable levels of active ingredients. This makes it difficult to give accurate doses and runs the risk of toxic side effects. Foxgloves — a source of medically useful chemicals.
These drugs are now used to treat many thousands of people around the world with heart failure and other cardiac problems. But the entire plant itself is highly toxic, and eating just a small amount can kill.
But this naturally-occurring chemical causes severe stomach irritation, which led to the German company Bayer developing an alternative version — acetylsalicylic acid — which was kinder to the tummy. Aspirin is now arguably one of the most successful drugs of all time, and is still being investigated for its potential in preventing or even treating cancer. As we said above, there is no good evidence that natural cannabinoids, at the doses present in simple cannabis preparations, can treat cancer in patients.
There is a strong and persistent presence on the internet arguing that cannabis can cure cancer. Despite what the supporters of these sources may claim, videos and stories are not scientific evidence for the effectiveness of any cancer treatment.
We know nothing about their medical diagnosis, stage of disease or outlook. People who make these bold claims for cannabis only pick their best cases, without presenting the full picture.
This highlights the importance of publishing data from scientifically rigorous lab research and clinical trials. Firstly because conducting proper clinical studies enables researchers to prove that a prospective cancer treatment is safe and effective.
And secondly because publishing this data allows doctors around the world to judge for themselves and use it for the benefit of their patients.
Internet anecdotes and videos prove nothing and benefit no-one — we need reliable, scientific research, which as discussed above is exactly what is going on. Not only to the thousands of our scientists, doctors and nurses who are working as hard as they can to find more effective treatments for the complex set of challenging diseases we call cancer, but also the hundreds of thousands of people in the UK and beyond who support this life-saving work through generous donations of money, energy and time.
Our aim is to beat cancer, and we believe that the best way to do this through rigorous scientific research aimed at understanding cancer on a biological level and working out how to prevent, detect and treat it more effectively.
As a research-based organisation, we want to see reliable scientific evidence to support claims made about any cancer treatment, be it conventional or alternative. This is vital because lives are at stake. If someone chooses to reject conventional cancer treatment in favour of unproven alternatives, including cannabis, they may miss out on treatment that could save or significantly lengthen their life.
They may also miss out on effective symptom relief to control their pain and suffering, or the chance to spend precious time with their loved ones. Furthermore, many of these unproven therapies come at a high price, and are not covered by the NHS or medical insurance. And, in the worst cases, an alternative therapy may even hasten death. They can increase the heart rate, which may cause problems for patients with pre-existing or undiagnosed heart conditions. Some research has shown that using cannabis may protect against cancer.
But other studies have shown an increased risk of cancer. 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.
