Hi, so I'm 24 years old and for the past few weeks I've been having pain in my left breast, it's been feeling sore, heavy and  swollen. I put it down to being due ony period but it's just persisted and with it just being the left side I had a feel and checked my breast and found quite a deep hard lump :( Saw my GP yesterday and I have to wait for an appointment to go down to the hospital. I'm really anxious and worried as breast cancer runs in my family.
