Patent ID: 6984498

Claim:
A method of cancer screening comprising the steps of: administering a compound to a patient for uptake into target cells, the compound having a fluorescent marker portion, and a radioactive portion in target cells, wherein said fluorescent marker portion is selected from the group consisting of 5-ALA, protoporphyrin IX, TCPP, hematoporphyrin derivative, photofrin, uroporphyrin, coproporphyrin, TPPS, and TMPP, and said radioactive portion is a radioisotope of copper; collecting the targeted cells from the patient; stimulating the collected targeted cells with a frequency of light that will cause pre-malignant and malignant cells to fluoresce; conducting tomographic scanning of the patient after the stimulating step if fluorescence is observed; and conducting radiation therapy by site selective ionizing radiation treatment from said radioactive portion of said compound wherein the compound is administered in a dose emitting between about 5 Gy and 25 Gy radiation.
