PSMA has been confirmed to be over expressed in vascular endothelial cells of various malignant solid tumors, such as breast cancer and renal cancer, which can provide growth advantages for various cancers by cutting the signal molecules involved in angiogenesis. Positron emission tomography (PET) imaging using radiolabeled molecules targeting PSMA can detect a variety of non prostate cancer solid tumors such as breast cancer and glioma. According to previous studies, PSMA can detect primary and metastasis lesions of breast cancer patients, and has a higher uptake value in triple negative breast cancer and HER2 overexpressed patients. The uptake may be related to tumor grade.
