The special effect formula for coughing up blood of lung cancer is not real, without scientific reason and basis. 1. Single folk remedies, secret prescriptions and special-effective prescriptions do not have the function and efficacy of treating coughing up blood of lung cancer, and most of the drugs will damage the function of patient’s organs after application. Therefore, lung cancer patients are advised not to believe in any folk remedies or health products. 2. Symptomatic treatment: patients coughing up a lot of blood can be treated by interventional therapy, in which the vascular supply of the tumor is blocked by ligation or embolization, so as to alleviate the symptoms of coughing up blood. 3. Allopathic treatment: Since lung cancer is a malignant tumor, besides allopathic treatment, radiotherapy (killing cancer cells by radiation), chemotherapy (cisplatin, carboplatin, etc.), targeted drug therapy (gefitinib, ceritinib, cetuximab, etc.), surgery (open thoracic surgery, assisted thoracoscopic surgery, robot-assisted thoracoscopy, etc.) are also needed. When coughing up blood, lung cancer patients need to go to regular hospitals in time for consultation and standardized diagnosis and treatment under the guidance of specialists, and should never use drugs indiscriminately.
