1. CBD May Help Reduce Tumor Size and Growth
Initial findings suggest that CBD may act to directly limit the growth and spread of cancer cells. While this topic has yet to be explored in detail for dogs, CBD has been linked to helping mitigate cancer cell growth and even kill cancer cells in human and mice models of cancer.
CBD treatment and cancer cell reduction has been associated in studies of leukemia, colon cancer, and breast cancer, among others. It’s thought that CBD may act to suppress cell growth through a variety of mechanisms, including protecting DNA inside cells from oxidative damage, which can lead to cancer cell formation.
Other studies are suggesting that CBD may increase the efficacy of existing treatment plans when used as a concurrent supplement. A 2018 study showed that radiation alongside CBD dosing was more effective for killing pancreatic and lung cancer cells in mice than radiation therapy alone.
If substantiated, CBD should allow veterinary oncologists to reduce the amount of radiation used on dogs with cancer, thereby reducing adverse side effects on the healthy surrounding tissues.
A similar recent study found that CBD helped augment chemotherapy treatment in mice with pancreatic cancer. Specifically, data showed that mice treated with a combination of CBD and gemcitabine (a chemotherapy drug) lived almost three times longer as those treated with gemcitabine alone.
When it comes to CBD’s potential as a primary cancer treatment, further research is of course needed. But if preliminary findings are anything to go by, then there’s good reason to believe CBD will soon become a mainstream tool in the fight against canine cancer.
2. CBD Helps Minimize the Harmful Side Effects of Other Treatments
Beyond directly reducing tumor growth, CBD plays a wider and far more well-established role in helping dogs through the difficult side effects of chemotherapy and radiation—as well as the upset of a cancer diagnosis.
