Yes, cytopathology can be used to assess the depth of cancer invasion in certain cases. Cytopathology is the examination of cells and tissues under a microscope to diagnose diseases, including cancer. In certain types of cancers, such as skin cancer (melanoma), cytopathology techniques like fine needle aspiration cytology (FNAC) or brush cytology can be used to assess the depth of invasion by analyzing the characteristics of the cancer cells obtained from a biopsy. This information can help determine the stage and prognosis of the cancer, as well as guide treatment decisions. However, it is important to note that cytopathology may not always provide the full extent of invasion and other imaging or histopathological techniques may be needed for a comprehensive evaluation.
