Kidney cancer tumor cells are particularly prone to metastasis, with the lungs being one of the common sites for metastases. Once lung metastasis occurs in patients with kidney cancer, numerous symptoms can appear. Typical symptoms include coughing, scanty sputum, severe irritating dry cough, palpitations, chest tightness, shortness of breath, and even chest pain, as well as coughing up blood or severe hemoptysis. Therefore, patients with lung metastases from kidney cancer who exhibit these symptoms should seek medical attention promptly and undergo a lung CT scan. Additionally, patients may experience an increase in body temperature, fevers, weight loss, dizziness, anemia, and particularly fatigue. There may also be a loss of appetite and a general feeling of weakness, which should draw the patients' attention.
