Several organs are located under the right breast, including the liver, gallbladder, and pancreas. The right rib cage protects these vital organs, as well as the right lung, parts of the digestive system like the large and small intestines, and the right kidney, ureter, bladder, and urethra.
It's important to note that pain under the right breast could be a symptom of a variety of conditions, such as pleurisy, hernia, or rib injury. If you experience persistent pain or other symptoms, it's best to consult a doctor for a proper diagnosis and treatment.
