Breast Cancer/breast lump


Around four months ago, I noticed a lump that felt like a marble between the top part of the breast and clavicle.  I had an ultrasound, which showed the lump at the top of the implant,but could not tell me if the lump was from a rupture to the implant or part of the breast tissue.  I had a mammogram that showed dark areas in both sides and additional tests were requested.  I had an MRI done and they confirmed that it wasn't the implants and that they could not see anything of concern.  I was scheduled for a biopsy of the lump, however they cancelled the appointment & stated that because of the absence of imaging on the MRI, it was not needed.  The lump is very palpable and causes slight pain when touched and moved.  Should I demand a biopsy on the lump to confirm it is non-cancerous?  How can a MRI tell me if it is cancerous or not?  why can I feel it and the MRI did not pick it up when it is the size of a marble and can be felt by whoever touches it.  What should I do next?

I can noy explain why it can not be seen on your MRI scan. If I were you I would DEMAND a biopsy, easiest & simplest in the form of a fine/thin needle biopsy in order to KNOW what this is. If it can be felt as you describe it such a biopsy can be guided by touch. It can also be guided by ultrasound since you state that it could be seen there. Such a biopsy can also probably explain why MRI could not catch it. Good luck!
