is it necessary that breast pain signifies cancer?
No. In fact pain more often than not means something other than cancer. Very likely is fibrous cysts which are painful to the touch and if large enough can be aspirated .
No don't worry it's normal but if it increases or is unbearable do a breast exam just to make sure
No, but you should see a doctor right away.
Not exactly, there could be other reasons! Do not panic! See a doctor by the way!
Breast pain and tenderness is often a symptom of your menstrual cycle.
