Invasive cancer without metastasis can generally achieve clinical cure after surgery. Invasive cancer without metastasis is usually an early stage cancer with relatively mild condition. As long as the patient cooperates with professional doctors to undergo local surgical resection in a timely manner, and if necessary, follow the doctor’s arrangement to carry out postoperative chemotherapy, radiotherapy and other follow-up treatments, the cancer cells can be effectively eliminated and prevented from spreading and metastasizing, so that the patient can achieve the goal of clinical cure and have a long term survival. However, for invasive cancer with metastasis, i.e. intermediate and advanced tumors, extended or radical surgical resection is required and supplemented with postoperative radiotherapy as appropriate. Therefore, once the signs of malignant tumors are found, it is necessary to go to regular hospitals for professional examination to confirm the diagnosis and intervene in standard treatment as early as possible.
