The disadvantages of lung cancer ablation surgery are that there is a chance of damaging lung tissues, the disease may also recur, and some patients may experience discomfort such as pain, cough, bleeding, and fatigue after treatment. Lung cancer is a kind of malignant tumor originated from bronchial mucosa or glands in lungs, while ablation surgery mainly utilizes the thermal effect of ultrasound to pass through human tissues, gather in the designated target area, and accumulate the energy to a sufficient intensity, thus destroying the tissues in the target area and achieving the purpose of damaging the lesion area. Any deviation during ablation treatment may lead to failure of puncture or incomplete ablation of the lesion, especially if the tumor site is deep, which can damage normal lung tissue. As the ablation procedure only treats the local area but does not completely kill the cancer cells, the residual cancer cells left after treatment may recur again. Some patients may have uncomfortable symptoms such as pain, cough, bleeding, fatigue and vomiting after treatment, and a few patients may also be accompanied by complications such as pneumothorax and pleural effusion. If patients with lung cancer experience discomfort after ablation surgery, they need to find out the cause of the disease in time.
