The presence of pressure pain below the navel does not necessarily mean cancer, but is mostly due to inflammatory diseases, so patients can rest assured. For cancer, auxiliary examinations are needed to reach a judgment. In particular, pathological biopsy is needed to confirm whether it is cancer or a benign disease. The organs below the belly button are mainly the uterus, bladder, and also the intestines. The presence of inflammatory disease in these organs is associated with lower abdominal pressure pain. When peritonitis occurs, pressure pain can also be present, but it is manifested as full abdominal pressure pain. Patients are advised to visit the hospital and cooperate with the doctor for a detailed examination to help understand the presence of acute abdominal disease and, if necessary, to cooperate with the doctor for active treatment.
