I will be 22 in 3 weeks and I recently found a lump in my left breast above my nipple, I called my doctor and had an appointment 2 days later, he sent me to have an ultrasound done, it came back and he said my "lump" is 3.8 centimeters an something about " echo" and " float", and that there is no liquid inside my lump, my app was June 26, my doc said to keep eye on it and if it he's bigger to call him for another app before my 6 week breast check up. My lump has indeed gotten bigger ,harder and more tender. I'm so confused as to what is actually in my breast and even though its not time should I make an app?! Help!
