Tumors may metastasize early. Although early stage tumors have relatively small lesions, small number of tumor cells and low destructive power, the possibility of recurrence or metastasis cannot be completely ruled out. Some patients with early stage tumors who have undergone radical resection surgery but their conditions are not under control may still suffer from recurrence or metastasis, so they should cooperate with professional oncologists to carry out subsequent treatments, including chemotherapy, radiotherapy, endocrine therapy and targeted therapy. If the tumor is detected at an early stage and radical resection surgery is taken in time, and the result is more satisfactory, the prognosis is better and recurrence or metastasis may not occur. Therefore, once the tumor is detected at an early stage, it is necessary to go to the regular hospital as soon as possible to improve the relevant examination, carry out pathological analysis and clarify the tumor typing in a timely manner, and cooperate with professional oncologists to formulate effective treatment plans to effectively inhibit the growth of the tumor.
