Lump in breast, Help!

i found a small hard lump in my breast it doesnt hurt nor does it move around alot my right breast has felt tingly the past few days kinda itchy but cant seem to make it stop, the lump isnt on the skin it feels deep, am 30yrs old and also having problems getting pregnant, i am going to see a doctor in a week should i wait or should i go earlyer? my mum had cervical cancer when she was younger and iv also had cyists in my hand in the past but these really hurt and caused alot of pain, could this be just another one or something to worry about
