Hello, the situation you said is relatively simple, and the specific situation is still unclear, so it is impossible to make an accurate judgment.

Suggestion:

This situation should consider several situations, one is the tumor or mass in the abdominal cavity; The second is the tumor or mass of the abdominal wall itself; Third, it may be local abdominal hernia (such as incisional hernia, etc. So I suggest you go to the hospital for an operation to make sure.
