Soft tissue mass on forehead after trauma - can I get surgically removed? (photos)

I had forhead trauma 2 years ago that has resulted in me having a soft/rubbery lump on the left side of my forhead with some indentation above the lump when I apply compression to the lump it goes away but once compression is lifted it gradually starts to come back again the lump is painless i had a CT scan done that has showed no fracture of any other abnormalities. I would like to know what this could be? Is this something I could get surgically removed,? Kind regards Hassan
