Cancer patients may be cured through active treatment at an early stage. When cancer is detected at an early stage and actively treated, the cure rate is usually very high, but it also depends on the nature, size and stage of the tumor, and the survival rate of advanced cancer is very low. Cancer manifests mainly in the form of localized lumps, which usually develop invasively and may produce symptoms such as ulceration, infection, bleeding, pain, etc. Lymph node and distant organ metastasis may also occur. Cancer can be cured, especially well-differentiated tumors and tumors in early stage, after timely and standardized treatment, the survival period of patients can be prolonged. Cancer patients should have regular medical checkups, pay attention to their body weight and the presence of abnormal masses, and go to the hospital in time when any abnormality occurs.
