Hi, im awaiting to go to the breast clinic as went to GP last week with sore left breast. She's referred me and I've got an appointment in 10 days. My breasts have always been quite lumpy and get very sore before my periods. However, the pain started just after my last period this time and hasn't gone away. The left breast has a burning pain through most of it and is bigger than the right. Has anyone else had this pain without an obvious lump and it's been cancer? I'm 52 next week and have young children and can't sleep or think straight at the moment.
