PFTs are crucial in cancer care for several reasons. They help in assessing the baseline lung function of cancer patients, which is vital for planning treatments such as surgery, chemotherapy, and radiation therapy. These treatments can impact lung function, so having baseline data allows for better management and monitoring of potential side effects. PFTs are also vital in detecting lung involvement in cancers such as lung cancer, mesothelioma, and metastases from other primary cancers.
