CBD, short for cannabidiol, is part of a class of compounds called cannabinoids. These compounds interact with the body’s endocannabinoid system (ECS), which plays a crucial role in maintaining homeostasis and regulating various physiological functions. Through its interaction with the ECS, CBD can influence processes such as inflammation, immune response, and cell growth.

CBD has shown promise in shrinking tumours, and this article will explore the research supporting this claim.

But before we continue, it is important to stress that CBD and medical cannabis is not a cure for cancer. Both have shown a certain level of efficacy in reducing tumour size in initial research and trials, but much more research is required before any real claims can be made.

Key Takeaways

  1. CBD’s Potential in Cancer Treatment: CBD demonstrates significant potential in cancer treatment, with studies indicating its ability to reduce tumour size and enhance survival rates when used alongside standard treatments.
  2. Consultation with Healthcare Professionals: It is essential to consult healthcare professionals before integrating CBD into cancer treatment regimes to avoid potential interactions and ensure safe, effective treatment.
  3. Legal and Regulatory Aspects: The legality of CBD varies by region. In the UK, CBD products must contain no more than 0.2% THC and cannot be legally marketed for medical use. Staying informed about current laws and regulations is vital.
  4. Future Research Directions: Ongoing research is crucial to determine optimal dosing, administration methods, and the long-term safety of CBD. The potential for combining CBD with other therapies also warrants further exploration.
  5. Enhanced Quality of Life: CBD’s ability to alleviate symptoms and its relatively favourable side effect profile offer hope for improved cancer treatment outcomes and enhanced quality of life for patients.

How CBD may help to shrink tumours

The therapeutic potential of CBD in tumour reduction has garnered considerable attention from scientists engaged in cancer research. Although further studies are necessary to comprehensively comprehend its efficacy, existing evidence indicates that CBD possesses anti-tumour properties that operate through diverse mechanisms.

Inducing apoptosis

One of the key ways CBD may contribute to tumour reduction is by inducing apoptosis, or programmed cell death, in cancer cells. Apoptosis is a natural process that eliminates damaged or abnormal cells from the body. CBD has been shown to stimulate apoptosis in cancer cells, effectively triggering their self-destruction and preventing further tumour growth.

Inhibiting angiogenesis

In addition to apoptosis, CBD has demonstrated the ability to inhibit angiogenesis, the formation of new blood vessels that supply tumours with nutrients. By disrupting the process of angiogenesis, CBD can cut off the tumour’s blood supply, starving it of essential resources and impeding its growth.

Regulating the immune system

Moreover, CBD’s interaction with the immune system plays a significant role in its anti-tumour effects. CBD has been found to modulate immune responses, enhancing the body’s natural defence mechanisms against cancer cells. It can stimulate the immune system to recognise and destroy cancer cells more effectively, bolstering the body’s ability to fight tumour growth.

Reducing inflammation

Furthermore, CBD possesses anti-inflammatory properties, which may contribute to its tumour-shrinking potential. Chronic inflammation is often associated with cancer development and progression. By reducing inflammation, CBD can create an unfavourable environment for tumour growth and metastasis.

The evidence for CBD shrinking tumours

The evidence supporting the tumour-shrinking properties of CBD is derived from a combination of animal and human studies. Animal studies have delivered promising results, showing that CBD can inhibit the growth of tumours in various types of cancer. These studies often involve implanting tumour cells in animals and then administering CBD to observe its effects on tumour size and progression.

Similarly, human studies have also provided valuable insights into the tumour-reducing potential of CBD. Although the number of clinical trials is still limited, preliminary findings have shown promising results. For instance, a small clinical trial involving patients with glioblastoma, a type of brain cancer, found that CBD, when used in conjunction with standard treatment, was associated with a reduction in tumour size and improved survival rates.

Potential side effects of CBD as a cancer treatment

Before utilising CBD as a cancer treatment, it’s crucial to understand the potential side effects it may entail. Although CBD is typically well-tolerated, some individuals may encounter adverse effects such as fatigue, appetite changes, dry mouth, diarrhoea and dizziness. It’s important to recognise that the intensity and occurrence of these side effects can differ among individuals based on their unique physiology and response to the treatment.

In comparison to traditional cancer treatments like chemotherapy and radiation therapy, CBD is generally considered to have a more favourable side effect profile. Traditional treatments often come with a range of side effects that can significantly impact a patient’s quality of life. These may include hair loss, nausea and vomiting, fatigue, weakened immune function and more. In contrast, the side effects of CBD are generally milder and may be better tolerated by patients.

It is, however, crucial to consult with a healthcare professional before using CBD as a cancer treatment, especially if you are already undergoing other cancer therapies. They can assess your specific situation and provide guidance on potential interactions and the best approach for integrating CBD into your treatment plan. Monitoring and open communication with your healthcare team are essential to ensure the safety and efficacy of any treatment regimen.

Legal and regulatory issues surrounding CBD and cancer treatment

The legal and regulatory landscape surrounding CBD and its use in cancer treatment is an important aspect to consider. In the United Kingdom, CBD is legal. Products containing CBD are only permitted a maximum of 0.2% THC (the psychoactive compound in cannabis). It is also very difficult for CBD products to be legally marketed as being for medical use.

Additionally, in the UK, the law around cannabis-based medicines in general and CBD in particular is in something of a state of flux. In general, the easiest way to keep on top of current laws and policy is to check on the website of a reputable vendor.

Future directions in CBD research for cancer treatment

The field of CBD research for cancer treatment continues to evolve, and there are several potential areas for future investigation. One area is the exploration of optimal dosing and administration methods to maximise CBD’s effectiveness while minimising side effects. 

Additionally, there is a need for clinical trials that specifically evaluate CBD’s efficacy in different types and stages of cancer. Further research is also needed to better understand the long-term safety profile of CBD and its potential interactions with other cancer treatments. 

Moreover, investigating the synergistic effects of CBD in combination with other therapies, such as chemotherapy or immunotherapy, holds promise for enhancing treatment outcomes. Overall, continued research efforts are crucial to expand our knowledge of CBD’s potential in cancer treatment and provide evidence-based guidelines for its use in clinical practice.


Is CBD a prescribable option for cancer treatment?

At this time, CBD is not a prescribable option for cancer treatment. It is not currently approved by any regulatory body as a treatment for cancer. However, some medical professionals may recommend CBD as an adjunct therapy to traditional treatments.

Can CBD cure cancer?

Currently, there is no evidence to suggest that CBD can cure cancer on its own. However, when used in combination with conventional treatments, CBD may have the potential to enhance treatment outcomes.

Is it safe to use CBD with other cancer treatments?

It is important to consult with a healthcare professional before using CBD in conjunction with other cancer treatments. Some interactions may occur, and careful monitoring by a medical team is necessary for safety and efficacy.

CBD for tumour control in brief

In conclusion, CBD holds significant potential in cancer treatment. Its anti-tumour effects, ability to alleviate symptoms and relatively low side effect profile make it an intriguing therapeutic option. The evidence suggests that CBD can shrink tumours by inducing apoptosis, inhibiting angiogenesis and modulating the immune system. 

That said, further research is needed to fully understand its effectiveness and optimal use in different types of cancer. Legal and regulatory issues pose challenges for patients and healthcare providers, but potential solutions, such as clearer regulations and improved access, are being explored. As the field of CBD research continues to advance, it offers hope for improved cancer treatments and enhanced quality of life for patients.
