There is a hard lump in the middle of the heart’s mouth fossa, which can be seen in the bone tissue, sebaceous cysts, bone tumors and so on.
1. Bone tissue: the main bone tissue in the fossa of the mouth of the heart is the sternum, if I am relatively thin and weak, can be clearly pressed to the sternum, so that the sternal peripheral nerves are stimulated and cause pain. Or if you have had a fracture of the ribs or sternum in the past, and a bone scab is formed after healing, there will also be a hard lump and pain when pressed.
2. Sebaceous cysts: Sebaceous cysts can easily appear due to the high oil secretion of the chest skin, and some of them will be painful when pressed.
3. Bone tumors: For example, osteoma and chondroma can form hard lumps in the fossa of the heart and become painful when pressed.
If there are hard lumps in the fossa of the heart and pain when pressed, it is recommended to go to the hospital for further examination in order to clarify whether there are lesions or not, so as to take corresponding measures to avoid delaying the condition.
