Summary

This study tests whether a single oral dose of cannabidiol (CBD) can reduce the anxiety people with advanced breast cancer feel before undergoing CT or PET scans. Participants are randomly assigned to receive either CBD or a placebo, and their anxiety levels are measured before and after the dose. The trial also tracks side effects and how acceptable the treatment is to patients.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: cannabidiol (CBD), taken as a liquid by mouth
What this could lead to: If effective, a single dose of CBD could offer a quick, non-drug option to calm anxiety before medical scans in people with advanced cancer.
What could go wrong: This is a small, early-stage trial, and CBD may not outperform a placebo. Side effects are possible, and results may not apply to all cancer patients.
