i am a 19 yrs old mother. my baby is now 1 yr and 2months, i only got 4 months of breastfeeding on my baby,, i can feel some pain on my breast and on my nipple. and when i squeeze it, there is a color less and sticky liquid coming out of my breast.. is the discharge liquid normal for a mother who only got 4 months of breast feeding? do mother who breast feed got breast cancer if they stop breast feeding?
