PAINFULL LUMP IN BREAST

If there is relation to your menstrul cycle it might be nothing. Get checked.

Please get this checked.  It is too risky.   Ten years ago I had some green oozing from my right nipple.  No pain what so ever.  Went to the doctor.  He says, its problably just a plugged milk duct.  I don't recall if I had a mammogram or not I think I may have.  Ten years later, I accidently bump myself right under my right armpit and I'm thinking, gees, that kinda smarted.  Two hours later, Im thinking, gees, that still kinda stings.  I was one month away from my monthly mammogram so I thought what the heck lets go in a month early and just take care of it.  Guess what.  Invasive Ductal Carcinoma.  to make it simple, cancer in the milk duct.  so I ask myself what was that really ten years ago.  
Anyhows, the doctor told me that if I had waited another month or two it would have changed my whole prognosis.  so, please please go get it checked now, now, now.  
And FYI,most of the the tumors are in what they call the upper quadrant.  Let me tell you where that is.  Take your finger, put it on your nipple, and draw a line up to your armpit.  Where the breast and the armpit come together is the most vulnerable spot for cancerous tumors. However, they can be anywhere and there are several types of tumors so please go get it checked out.
