CBD Oil and Cancer – Can it Help? A Complete Guide

CBD oil is made using extracted CBD from the cannabis plant. CBD has been used to treat many physical and mental ailments due to its various properties.

Cancer is the biggest cause of death in NZ, with most of us knowing someone who has experienced it (1).

Because of cancer’s many side effects, many have turned towards natural options like CBD oil to help prevent cancer and ease treatment.

I have treated and helped treated thousands of patients with cancer and I share what I have learnt from this experience below.

CBD oil and cancer

CBD oil is a natural treatment option commonly used as an alternative to traditional medicine for many diseases, like cancer.

While more research is needed to determine if CBD is a good option for cancer prevention, there have been promising results, including decreased side effects due to cancer treatment when CBD oil is used.

If you or a loved one has cancer, considering CBD oil and medicinal cannabis is a good idea.

Cancer treatment

  • Can CBD oil be used to treat cancer? There is some evidence to say that it is effective but more research is needed.

Investigating the relationship between CBD and cancer is still a relatively new area, so research is still ongoing. However, substantial evidence shows that cannabinoids can reduce tumour growth and slow or even stop cancer growth.

Researchers in 2014 suggested that CBD may help slow colorectal cancer cell growth while not affecting healthy cells after looking at colon cancer models. Similarly, researchers in 2019 showed CBD could induce tumour cell death by regulating several essential proteins. This decreased overall tumour volume (2).

Inflammation is often high in cancer patients. Cannabinoids can combat this and produce anti-inflammatory effects, acting as protective agents in neuroinflammatory disorders (3). This makes CBD an excellent treatment candidate for cancers with high inflammatory rates, like skin cancer.

Although we are a long way from making conclusive decisions, there is nothing stopping you or a loved one from trying CBD oil for cancer. It is a safe and natural option that may prove helpful.

Complementary treatment

  • Can CBD oil be used to treat the side effects of cancer treatment? Yes, CBD oil and medicinal cannabis is an effective treatment for pain, nausea and low appetite.

While treatment is necessary to kill off cancerous cells, the side effects experienced are not pleasant! These effects can be painful and long-lasting. Luckily, researchers have investigated how CBD may be used as a complementary treatment to ease some of the side effects of cancer, including pain, anxiety, and insomnia.

Pain is often noted as the most common side effect experienced. Because of this, pain relief can be essential to improve the patient’s well-being. A recent review looked at several studies to assess how CBD works in relieving chronic pain, with a range of pain conditions examined. Researchers found CBD was effective in overall pain management across many different pain types (4).

CBD may encourage sleepy feelings in individuals who have insomnia and anxiety as side effects. A recent study looked at CBD’s role in decreasing anxiety and improving sleep quality in a group of people who took just one CBD capsule daily. After a month, the majority of patients reported reduced anxiety (80%) and better sleep (67%) (5).

Nausea and low appetite are also common during cancer and cancer treatment. There is some evidence that CBD oil can help reduce nausea. However, this is an area where THC, the psychoactive component of cannabis, is more helpful. THC has been shown to reduce nausea and improve appetite in relation to cancer.

Eating well during cancer is very important as it fuels your body and provides energy. Loosing weight and muscle with cancer only adds to more suffering and anxiety which is not ideal.

If the idea of getting high in off putting, which it is for many people, rest assured that this is not the case. Using medicinal cannabis and THC oil in a medicinal way is about getting the benefit without the high.

Preventative treatment

  • Can CBD oil prevent cancer? CBD oil may help reduce obesity and lower cholesterol levels in the blood.

Preventative treatments work by reducing the key risk factors for developing cancer. There are many factors, but some common ones include obesity and increased cholesterol levels.

While obesity is mainly influenced by lifestyle factors, such as a healthy diet and exercise regime, many studies have investigated the relationship between obesity and CBD use. CBD has been shown to affect weight loss and weight gain since one of CBD’s main side effects is a change in appetite (6).

Animal studies show CBD influencing metabolism and decreasing food intake due to CBD’s interaction with several brain and lymphoid tissue receptors. These receptors play a crucial role in body metabolism (7).

Research is divided on CBD’s role in lowering cholesterol; however, several animal studies have been promising. A 2011 study involving mice suggests that CBD treatment can regulate cholesterol homeostasis in microglial cells, keeping blood cholesterol levels stable (8).

How does CBD help with cancer?

  • CBD works on the endocannabinoid system and helps reduce the symptoms of cancer.

Because cancer is a highly complex disease, it’s hard to pinpoint how exactly CBD helps slow or stop cancer growth. While many studies show CBD effectively relieves cancer symptoms and side effects, some research is still mixed.

So how does CBD for cancer works, then? The key lies in how CBD can regulate commonly experienced cancer side effects, including nausea, anxiety, insomnia, and pain. This can help ease symptoms in the patient, easing the cancer recovery process.

The endocannabinoid system is present in our bodies and is essential for food intake, fat and glucose regulation, and metabolism. It consists of endocannabinoids, their receptors, and some enzymes. CBD works by interacting with these receptors leading to pain relief and appetite regulation (9).

How to use CBD oil for cancer

  • It is important to use the right product and dose of CBD oil for treating cancer.

Before using CBD for cancer prevention or treatment, talking to your doctor can be useful. They will determine whether CBD or another form of medication is best suited for your symptoms and the correct dosage needed for your body.

Usually, a suitable dosage level to start at would be 25 mg. It is best to start with a small amount to test CBD’s effects on your body before gradually increasing it. Most research investigating CBD’s therapeutic effects has involved smaller doses.

CBD oil can be taken by putting the sample directly under the tongue, which increases the absorption rate (10). Choosing a reputable CBD oil company is essential. Ideally, identify companies that consistently produce high-quality products.

CBD side effects

  • CBD oil is very safe and well tolerated.

While side effects are minimal, they can still occur! These include nausea, dizziness, diarrhoea, and appetite change (11). CBD may also interact with other medications you take, so talk to your doctor if you are worried about this.

Side effects can often be decreased by lowering dosage amounts, limiting use (especially when first trying CBD), and choosing CBD products from reputable companies.

CBD for cancer: The bottom line

While research is still ongoing, numerous studies have suggested the positive role CBD oil may play in easing cancer treatment symptoms and limiting cancer risk factors. CBD can affect our bodies in various ways, so it’s crucial to find the correct dosage for you.
