Let’s take a closer look at how CBD may help people with cancer.
In animal models of cancer, there is strong evidence that cannabis can inhibit tumour development.
CBD may potentially improve the intake or efficacy of certain cancer-fighting drugs Trusted Source.

Here are a few researches that look promising:

• A 2019 review Trusted Source of in vitro and in vivo studies focusing on pancreatic cancer found that cannabinoids can help slow tumor growth, reduce tumor invasion, and induce tumor cell death. The study authors wrote that research into the effectiveness of different formulations, dosing, and precise mode of action is lacking and urgently needed.
• A 2019 study Trusted Source indicated that CBD could provoke cell death and make glioblastoma cells more sensitive to radiation, but with no effect on healthy cells.
• A large, long-term study Trusted Source of men within the California Men’s Health Study cohort found that using cannabis may be inversely associated with bladder cancer risk. However, a cause and effect relationship hasn’t been established. A 2014 study in experimental models of colon cancer in vivo suggests that CBD may inhibit the spread of colorectal cancer cells.
• A 2014 review Trusted Source of 35 in vitro and in vivo studies found that cannabinoids are promising compounds in the treatment of gliomas.
• Research from 2010 demonstrated the efficacy of CBD in preclinical models of metastatic breast cancer. The study found that CBD significantly reduced breast cancer cell proliferation and invasion.

These are just a few studies addressing the potential of cannabinoids to help treat cancer. Still, it’s far too soon to say that CBD is a safe and effective treatment for cancer in humans. CBD shouldn’t be considered a substitute for other cancer treatments.
