The presence of pain in the right side of the ribs is not necessarily cancer. If it is cancer, the chances of this are very small. First of all, there must be a history of cancer, such as prostate cancer, breast cancer, in advanced stages, these cancers may metastasize to the ribs, so it is necessary to actively improve the localized pain in the area of the MRI examination for clarification. If there is a fracture on the right side of the rib cage, it can also cause localized pain. Prolonged one position or long time repetition of a certain movement, repeated rotation of the chest, can also cause pain on one side of the rib cage. Because of these bad habits, it is easy to cause the soft tissues of the ribs to be stretched repeatedly, local congestion, edema, and the formation of aseptic inflammation, which will cause local pain. Some tumor diseases of the chest and lungs may also cause pain in the right side of the ribs. Localized purulent infectious diseases of the right side of the ribs will cause local soft tissue destruction, redness, swelling, heat and pain, and if there is pus formation, the pain will be more obvious.
