The most common type of tumor that grows in the lungs is a primary tumor of the lung, referred to as lung cancer. The vast majority are malignant. This is not always the case, but some may also appear benign, such as misshapen tumors, and it is most critical to define the pathology at this time. If the tumor is centrally located, a bronchoscopic biopsy is recommended at this time. If the tumor is peripheral, it is recommended to apply lung aspiration for biopsy. After the pathology is clarified, if the tumor is benign and has compression symptoms, it needs to be removed. And if the malignant tumor has distant metastasis, this is when it is not recommended and surgery should be chosen.
