It starts at a specific point in the manga, but I can't recall exactly without looking it up. You might want to check some manga forums or dedicated fan sites for the precise chapter.
The causes of lung lumps include smoking or dust, infection, autoimmunity, benign lung tumors, malignant lung tumors, and so on. Smoking or dust can cause an immune inflammation reaction, forming a granuloma. Nodules can also be caused by infections such as malaria, aspergillosa, and cryptococci. Immune diseases such as rheumatism, necrotizing, and sarcoidosis can also lead to the formation of noduli. Benign tumors of the lung, such as tumors, hamartomas, and cavernous tumors, may also cause these tumors. Lung cancer, such as lung adenomas or metastasizing malignant tumors, can also cause lung nodes to appear.
Sukuna does die in the manga. The way it happens is quite dramatic and ties in with many other elements of the story, adding depth and tension to the overall narrative.
The lung nodes could be cured. The treatment of lung nodes depends on the nature and cause of the nodes. Benign lung nodes can usually be treated with medication or surgery. For infected nodes, antibiotics can improve the absorption of the nodes. However, the treatment of malignant lung nodes is relatively difficult, and long-term treatment is needed to control the malignant tumor. Therefore, whether or not the lung nodes could be completely cured depended on the nature of the nodes and the individual's condition.
Lung nodes were damage caused by lung tissue damage. According to the information provided, the causes of the formation of lung nodes included foreign body aspiration, inflammation, vascular disease, benign tumors, malignant tumors, and so on. Scars after infection, inhaling harmful substances, smoking, inflammation, vasular diseases, benign and malignant tumors can all lead to the formation of lung nodes. The risk of lung nodes depended on their nature. Benign nodes were usually caused by foreign body aspiration, inflammation, vasectomy, or benign tumors. However, the specific formation mechanism and cause may require further pathological testing to determine.
The treatment of lung nodes depends on the cause and nature of the nodes. Lung nodes can be divided into infectious and non-infectious. For infectious nodes, treatment methods include taking corresponding anti-infective treatments according to different pathogen, such as antibiotics, anti-inflammatory drugs, and antimycotic drugs. For non-infectious nodes, the treatment method was based on the pathological type to choose the corresponding chemotherapy, radiation therapy, targeted therapy, or immune suppression therapy. For benign tumors, conservative treatment was a common method, including observation and traditional Chinese medicine treatment. Surgery was a common treatment method, especially for malignant or enlarged nodes with increased solid components. However, the specific treatment plan should be judged and decided by the specialist according to the specific condition of the patient.
