Small lump sitting on upper rib cage.

hi guys, I have noticed a small lump on the very upper area of my rib cage on my right hand side. it's a small soft lump and has that squishy sort of feeling of a gland but i didn't think there would be any glands in an area of skin/muscle between my actual ribs and my skin. it's barely noticeable in pictures but hopefully you can see it. There is nothing on the symmetrical side on my left.

As i said it is barely noticeable but if you trace your eyes to the right a few centimetres from my nipple where there is a brighter spot of skin (because the light is hitting the raised lump)
