Welcome to icliniq.com.
Your X-ray is fine (attachment removed to protect patient identity) and no lump is visible on the X-ray. The first possibility and common cause is a lipoma.
If possible, you may upload a picture of the lump. Also, let me know, whether it is just below the skin or attached to the sternum, in upper or lower part of the sternum, duration of lump.
So, from the description you gave, it is likely a lipoma which is a painless swelling, below the skin, slightly mobile and not attached to the bone. It is benign and usually needs no treatment. However, one may undergo minor surgery to remove it for cosmetic concerns.
It is not related to uric acid. For uric acid, have a healthy lifestyle, exercise and try to achieve weight loss. Also, limit non-vegetarian food if you are having in plenty. It needs treatment like Febuxostat if more than 10.
Hope this helps you and get back if you have any doubts.
