Wow that's really great news and for some reason I had a good feeling about your mom from beginning. Many people hear the word "mass" and assume its cancer - sometimes its a benign (not spreading) tumor. Naturally if the non threatening tumors in lung or brain, it just has to be removed. The nerve wracking part is waiting for the treatment and laboratory results. You did very well (((Sabrina)))) and I hope this will encourage you mom to appreciate everyday.
