Is it true that gabapentin use causes breast cancer?

No. A Kaiser Permanente Northern California reanalysis with 7.5 additional years of follow-up found the previously weak association between gabapentin use and breast cancer lost statistical significance (OR 1.02, 95% CI 0.94-1.10), indicating gabapentin use does not cause breast cancer.
