Technologies are generally described for detecting diseased tissues through fiber optic based Raman spectroscopy, image acquisition, and/or RF induced hyperthermia treatment of the detected tissues in an integrated manner. A fiber optic bundle for carrying optical and RF signals for the spectroscopy, visual imaging, and RF ablation may also be used to detect a temperature of the treated tissue such that level and duration of the RF signal can be controlled for optimum results. A shielding configuration in the form of a coaxial waveguide of the fiber optic bundle may be used to guide and deliver the RF signal. Sources and detectors for the optical and RF signals may be integrated into an endoscopic probe containing the fiber optic bundle or be externally positioned. An integrated or remote controller may be employed to manage the optical imaging, spectroscopy, RF ablation, and thermal sensing operations.
