I'm 20 years old and i have a lump in my breast for so long now. I never really cared about it until recently and i decided to go to my doctor. She felt it and said that it's slippery and mobile. When i asked her if i should be worried, she said no it's benign however still referred me to get an ultrasound on it due to family history of breast cancer( paternal grandmother had it) I'm scared and anxious about my appointment on tuesday.
