Common prescription drugs may trigger or exacerbate the development of breast cancer. These medications may be linked with causing the disease in animal or man:
Spiroctan or Aldactone in the US (spironolactone)
Elavil (amitryptiline hydrochloride)
Prozac (fluoxetine hydrochloride)
Cholesterol lowering drugs
All fibrates and statin drugs, particularly Lipostat, or Pravachol in the US (pravastatin).
According to the National Cancer Institute, nitrogen mustard, vincristine, procarbazine and prednisolone (a steroid prednisone in the US) for treatment of Hodgkin’s disease and other cancers place women at a significantly higher risk for developing breast cancer 15 or more years later.
