I’m a 19 year old female and about 6 months

Patient: I’m a 19 year old female and about 6 months ago I noticed a bump on the right side of my chest. I didn’t think much of it but happened to mention it to my dad tonight and he felt it and is rather worried. He thinks I should go to the walk in tomorrow just to make sure. I googled and saw that many people to get lumps on their sternum and it’s completely normal. I’m not sure if this is on my sternum because it’s on the right side of my chest not the middle. Should I be worried?
