The first thing that should be determined is the location of the lump, whether it is growing on the rib cage or on the soft tissue surrounding the rib cage. Once this symptom occurs, you should go to a regular hospital and examine local radiographs or CT to clearly and accurately determine the location of the lump, as well as the nature of the lump initially. If a lump appears on the rib cage, most of them are benign tumors of the rib cage if there is no pain and other symptoms. Some patients with early malignant tumors may also produce a relatively hard localized mass. If there is no destruction of the ribs, that is, if there is a pathological fracture of the ribs, or if there is no invasion of the intercostal nerves, the pain may not be significant. Once the mass invades the intercostal nerve or causes a rib fracture, the pain will be very pronounced. Therefore, once this condition is detected, it should be seen promptly so as not to delay the best time for treatment.
