Most of the cases of vague pain in the right rib cage are not cancer, but clinical examination is needed to clarify the diagnosis. There are many clinical reasons for the vague pain in the right side of the rib cage. Firstly, patients need to clarify whether there is any history of trauma, such as rib fracture, heavy blow to the chest, fall, etc. Next, it is necessary to exclude any right-sided intra-abdominal organ pathology, such as long-term cholecystitis, gallbladder stones, hepatitis, etc., which can cause vague pain in the right rib cage during attacks. In addition, chronic chondromalacia and intercostal neuritis on the right side may also cause vague pain in the right rib cage. Of course, malignant tumors of the ribs can also cause rib pain. Malignant tumors metastasizing or invading the ribs from other parts can also cause rib pain, such as thoracic cancer and lung cancer invading the ribs. If patients have vague pain in the right rib cage, they can first visit the hepatobiliary surgery or thoracic surgery department of regular hospitals to clarify the cause of the disease and then treat it symptomatically.
