The triple-negative breast cancer is an aggressive subtype that has a high rate of relapse and a poor five-year survival rate. The Tumor Microenviroment influences the behaviors such as proliferation, migration and the formation of metastasis. We present the complementary imaging and subsequent analysis of the Tumor Microenviroment using Lightsheet Microscopy, Scanning Laser Optical Tomography and TPEF. The samples were imaged in different size and resolution scales and the three-dimensional information is obtained using the SHG-signal of collagen and fluorescence of labeled key markers. The results presented here may help to create a patient specific model of breast cancer.
