Ablation of breast nodules includes radiofrequency ablation, microwave ablation and laser ablation. The most common clinical ones are radiofrequency ablation and microwave ablation, through which the functional head of the ablation needle is punctured to the local tumor, and the radiofrequency magnetic field is used to make the local temperature rise rapidly to more than 60℃, which causes protein denaturation and necrosis of the tumor cells, thus inactivating the tumor cells, and then the nodules are finally eliminated through human absorption to achieve the effect of cure. Breast nodule ablation is suitable for benign nodules and benign tumors, and the instrument is not recommended for malignant tumors. For those who have lost the chance of surgery in advanced stage of breast cancer, radiofrequency ablation palliative treatment can be used to shrink the tumor, alleviate the symptoms and promote the healing of ulcerated wounds to achieve the therapeutic effect.
