I am not a doctor, but I have survived breast cancer twice. I have never heard of a cancerous tumor "bursting," however, I would strongly suggest your friend get a second opinion immediately. Mammograms are very good at detecting even the smallest tumor, yet they are not perfect and cannot detect all cancers.
MRI's are much more definitive. The most important thing your friend can do is ADVOCATE for herself, and insist on further testing. I hope this answer helps, and I wish your friend the very best.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
