I am 39 years old and a mother of 3 year old girl. I have been experiencing pain in both my breasts since last two days and feel lumps too. This happens usually before my menstrual cycle and pain and lumps fade away by the end of the periods. My periods is due in 10 days time. The pain already stared and I feel lots of lumps. Should I go for cancer screening now or wait till my periods get over?
