Hdi, may I answer your health queries right now ? Please type your query here...I have a small, hard lump in my breast. I am only 32 years old. I am not too worried, but I will make an appointment with my doctor. My question is about what it means for the lump to be "movable" versus immovable? The lump does seem to move, but how can I tell that it is not just my other breast tissue moving?
