If my mammogram shows a mass, does that mean cancer?

No. That mass could be a benign cyst, or other anomalies. Mammograms and other diagnostic tools (such as Positron Emission Tomography scans or PET scans) are valuable tools for detecting small masses that could be tumors.

But only a biopsy can prove that any detected mass or anomaly is cancerous.

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.
