How can I have the lump on my neck removed? (Photos)

Hello! I've had this lump at the top of my neck by my jaw that makes my jawline look a bit off. It is only on the right side of my neck. I'm not sure how long I've had it, whether it's been a few years or my whole life. It's not painful but I do feel it when I touch it and can kind of squish it around. Do you know how/if I can have it removed by some cosmetic procedure ? Or perhaps even if this may be a cause for medical concern? Thank you!
