Four courses of chemotherapy for lung cancer, what is the problem with honest bleeding from the nose
Nasal bleeding in lung cancer patients after 4 courses of chemotherapy may be caused by non-disease factors such as drug factors and tumor recurrence. It may also be caused by an exacerbation of the disease, such as lung infection, brain metastases, etc.
1. Non-disease factors
1. Drug factors: If cisplatin injection, carboplatin injection and other chemotherapy drugs that are more harmful to the body are used during chemotherapy, it may damage the patient's bone marrow hematopoietic function, resulting in thrombocytopenia, which in turn causes nasal mucosal capillary rupture and bleeding;
2. Tumor recurrence: If lung cancer patients have genetic mutations, after 4 courses of chemotherapy, they may not be able to kill all the cancer cells in the body, and some cancer cells will remain and spread and metastasize, which can be manifested as the growth of new organisms in the nasal cavity, and will be accompanied by bleeding and other symptoms.
2. Disease factors
1. Lung infection: If lung cancer patients do not take good care of their bodies during chemotherapy, or do not take warm measures after chemotherapy, they are easily invaded by bacteria or viruses, which can induce respiratory inflammatory reactions such as pneumonia or bronchitis, and at this time, it will also cause capillary congestion and dilatation in the nasal cavity due to inflammatory stimulation, and even rupture and bleeding.
2. Brain metastasis: When lung cancer develops to an advanced stage, cancer cells will metastasize to distant places, the more common of which is metastasis to the cranial brain, at which time brain metastases will be formed, which will compress the surrounding tissues, and will also affect normal blood circulation and nerve conduction, and in severe cases, it will lead to increased intracranial pressure, and the above symptoms can also occur at this time.
In addition to the above relatively common causes, it cannot be ruled out that they are caused by other conditions, such as peptic ulcers, coagulation dysfunction, etc. It is recommended that family members take him to the hospital for treatment in time to avoid delaying his condition.
