What is the cause of multiple lung nodules after breast cancer surgery? What should I do?

Multiple lung nodules are usually found when patients undergo CT scans and find multiple round or quasi-round high-density shadows in their lungs. Multiple lung nodules after breast cancer surgery may be related to long-term smoking, pneumonia, tuberculosis, lung metastasis, primary lung cancer, etc. There is no fixed treatment method and targeted treatment is required. The specific analysis is as follows:

1. Long-term smoking: If breast cancer patients do not quit smoking in time during treatment and continue to smoke for a long time, the nicotine in cigarettes will damage the lungs, resulting in multiple nodules. It is necessary to quit smoking in time and stay away from secondhand smoke.

2. Pneumonia: It is mostly caused by infection with pathogens such as bacteria and viruses. Since breast cancer patients have relatively poor body resistance, the chance of pneumonia is relatively high, and lung abnormalities will be found during imaging examinations. It is necessary to follow the doctor's advice and take medications such as amoxicillin capsules, azithromycin tablets, and cefixime capsules.

3. Pulmonary tuberculosis: It is mainly caused by infection with Mycobacterium tuberculosis. If breast cancer patients have close contact with Mycobacterium tuberculosis carriers or latent carriers, the probability of infection will be relatively high, which will induce coughing, sputum, chest pain, etc., and will also cause abnormal imaging examinations. It is necessary to follow the doctor's advice and take drugs such as isoniazid tablets, rifampicin tablets, and ethambutol hydrochloride tablets.

4. Lung metastasis: If breast cancer surgery cannot completely remove cancer cells, the cancer cells may metastasize to the lungs after surgery, which will cause lung nodules. You need to follow the doctor's advice to receive treatment through radiotherapy, chemotherapy, targeted therapy, etc.

5. Primary lung cancer: Lung cancer is a malignant tumor that originates from the trachea, bronchial mucosa or glands. If a breast cancer patient also has lung cancer, lung lesions will be found during lung examinations. Lung cancer requires individualized treatment under the guidance of professional doctors, such as surgery, radiotherapy, chemotherapy, etc.

Patients are advised to go to the hospital as soon as possible and receive individualized treatment from the doctor. Active treatment can delay the progression of the disease.
