[|Human|] HI I have a small, hard lump slightly of centre at the end of my sterum, If i look down while breathing out and pulling my tummy in its quite obvious, its noticeable.  Its not attached to skin by seems to be on the process thing where last ribs meet.
[|AI|]  Thanks for your question on Chat Doctor. By your description and history, I think you are talking about typhoid process. It is terminal part of sternum and in some individual, it is separate bone and can give feeling of hard lump on touch. So mostly it is typhoid process of sternum. So no need to worry much for this as it is a normal thing. But better to rule out other things by ultrasound examination of local part. If ultrasound is normal then no need to worry about this thing. It is normal typhoid process.
