Breast cancer

Desiree
Had a physical with my pcp. Discussed problems I have been expierencing; weight gain, hot flashes, tired, sore breast, discharge, sharp pain in breasts, texture of breasts changed. He has me getting a mammogram, 24 hour urine test and a sleep study. I'm only 28 I know that's just a number. Anyone else experience this, could it be breast cancer?
