Rectal cancer tumor sprouting suggests that the tumor has spread and metastasized the surrounding cells and tissues, and the situation is more serious. The sprouting of rectal cancer indicates that the tumor cells have invaded the surrounding normal tissue cells and caused the surrounding tissues to overgrow and form the morphology of sprouting, which is the evidence of spreading and metastasis of the tumor tissues. This situation indicates that rectal cancer has already developed to middle or advanced stage, and requires early surgery and further postoperative radiotherapy according to postoperative pathological examination and immunohistochemistry examination results, in order to control the disease. Early detection of rectal cancer can be effectively controlled in the long run, so please do not worry too much. It is recommended to go to the hospital for consultation to confirm the diagnosis and standardize the treatment under the guidance of physicians to improve the cure rate and survival rate.
