Breast cancer in a patient under levodopa treatment
Abstract:
A case history of a patient who developed mammary cancer (T1N1bMo) after 5 1/2 years of continuous treatment with Levodopa for Parkinson's disease is presented. The prolactin inhibition by the Levodopa was verified, and the clinical and mammographic growth, the doubling time, and the labeling index of the tumor were determined. The results were not significantly different than those obtained from patients with breast cancer not under treatment with Levodopa. The rapid growth and evolution of this tumor suggests that prolactin does not have an inducer or promoter effect in mammary cancer.
