Hi Darlene - There's no telling what that sensation in your breast might be from. That said, why not get it checked out? Pain/tingling is generally not a symptom of breast cancer, but inflammatory breast cancer is characterized by a hot sensation, pain, and redness, much like an infection. Since this is happening in only one of your breasts (pretty much ruling out somekind of systemic thing),  best to get it looked at. - PJH 

Hi Darlene,

When I found 1 of my lumps and went for my mammogram and ultrasound I told the radiologist it didn't relly feel like warm sensations through my breast but more like milk filling up in them after having a baby. I didn't breast feed but my breast did feel up with milk and you don't forget those motherly feelings. So definetly get checked out if you haven't already. It's best to know than worry about it. Good Luck
