What could cause a hard bump on the sternum?

Answer by  hchanrn (16)

If you had surgery on the sternum, ie any type of open thoracic surgery where the sternum is opened up or physical injury from a fracture, the sternum may heal up with a spur. Sort of like bone spurs that can form at the joints. Normally there are small bumps on the sternum where the cartilage and the sternum meet.

You may just have a boy protrusion of the sternum. It could be a benign mass. The bump may be an injury. Your doctor will be able to tell whther or not the lump is of bone or other matter in an x-ray.

A hard bump located on the sternum could possibly be a cyst. It could also be due to an injury.

Any type of bump or protrusion to the sternum is probably caused by some sort of injury. Since the sternum is bone and calcium, injury to this area is frequent and not uncommon. Sternal injuries are seen quite often in football players from taking a hard blow to the area.

It could be any number of things from an allergic reaction to something that needs to have a biopsy done. The only way to truly know the cause is to go see the doctor.

:/ good grief!! A bone spur such as this on the sternum is lack of hydrochloric acid in the stomach and therefore poor calcium absorption......
