What are the symptoms of lung metastasis from colorectal cancer

Due to the insidious nature of rectal cancer and atypical early symptoms, many patients have already developed distant metastasis when diagnosed, which increases the difficulty of treatment and affects the cure rate of patients. The lungs are a common site of metastasis for patients with rectal cancer. There are many symptoms of colorectal cancer metastasis to the lungs, which can be judged based on the patient's own situation.

The lungs are the most common extrahepatic metastasis site of rectal cancer, with a high incidence rate. Lung metastasis of rectal cancer not only increases the pain of the patient, but also, if not treated in time, the median survival time is less than a few months, and only a small number of patients survive for more than a few years. Therefore, special vigilance is required in daily life. Understanding what abnormalities will occur when rectal cancer metastasizes to the lungs can help patients detect the disease in time, avoid delaying treatment, and affect the patient's survival time and quality of life.

Cough is the first symptom of colorectal cancer metastases to the lungs. It is not easy for patients to take it seriously in the early stage. As the disease progresses, patients will experience symptoms such as persistent coughing, coughing up blood, chest pain, chest tightness, and lumps. When there are complications such as carcinomatous lymphangitis, a large amount of pleural effusion, atelectasis, or compression of the superior vena cava, patients will also experience symptoms such as dyspnea and persistent fever, which poses a serious threat to the patient's life and health, and special vigilance is required.

When rectal cancer metastasizes to the lungs, the disease has usually developed to the late stage. At this time, patients must actively undergo effective treatment to avoid endangering their lives. When rectal cancer develops to the late stage, the patient's chance of cure is low. The purpose of treatment is to extend the patient's life as much as possible and improve the patient's quality of life. Therefore, patients who have been diagnosed need to choose a reasonable treatment plan.

When rectal cancer metastasizes to the lungs, the opportunity for surgical treatment has been missed because surgery can only be used for local resection and causes great trauma to the body. For patients with better physical conditions, palliative surgery can be used to remove local lesions, control the disease, and lay the foundation for other treatment methods.

Radiotherapy, chemotherapy and traditional Chinese medicine are the most common treatment options for patients with lung metastasis of rectal cancer, but radiotherapy and chemotherapy have significant side effects and need to be supplemented with traditional Chinese medicine.

Traditional Chinese medicine-assisted radiotherapy and chemotherapy can not only improve the therapeutic effect, but also reduce its toxic side effects. In addition, for some elderly, weak, and rectal cancer lung metastasis patients who cannot withstand surgery, radiotherapy and chemotherapy, conservative treatment with traditional Chinese medicine can be used to prolong life to the greatest extent, improve the quality of life, and even achieve long-term survival with tumors.
