The lesion in her lungs was measured at 41 millimeters in June 2018 and had reduced to 10 millimeters by February 2021.
Scientists have advised caution after a report emerged of a woman whose lung cancer tumor shrank after she took regular doses of CBD oil.
People have also wondered whether CBD could be used as a cancer treatment, but this link remains inconclusive, according to MedicalNewsToday.
Meanwhile, scientists not involved in the case report have said that while the case appears encouraging, it should be taken with caution.
Indeed, the case report authors note that it is difficult to conclude whether the THC in the woman’s oil contributed to the tumor reduction or if it was just the CBD component that may have had a positive effect.
These showed that the tumour was progressively shrinking, reducing in size from 41 mm in June 2018 to 10 mm by February 2021, equal to an overall 76% reduction in maximum diameter, averaging 2.4% a month, say the report authors.
It may be worth exploring further the use of cannabidiol (‘CBD’) oil as a potential lung cancer treatment, suggest doctors in BMJ Case Reports after dealing with a daily user whose lung tumour shrank without the aid of conventional treatment.
Chemically similar to these endocannabinoids, cannabinoids can interact with signalling pathways in cells, including cancer cells. They have been studied for use as a primary cancer treatment, but the results have been inconsistent.
This is just one case report, with only one other similar case reported, caution the authors. And it’s not clear which of the CBD oil ingredients might have been helpful.
