The present application includes a method for introducing a hormone directly into an affected area within a tumor. The method includes penetrating the affected area of the tumor with a biopsy needle in order to obtain a biopsy specimen. The specimen is withdrawn along with the biopsy needle. A hormone implant is inserted into the void space left behind as the specimen was removed. The method may also include directly inserting the implant and a treating substance into the tumor without the removal of the biopsy specimen. The implant may have various shapes in order to maximize surface contact. The implant is also configured to have a time release function to regulate dosage delivery.
