My 33 year old niece has just been diagnosed with diffuse B-cell NHL. She has a mass in her chest cavity and has undergone her first chemo threatment. She just gave birth 4 months ago to a beautiful baby girl. Her family is devastated. If anyone has any experience on what to expect please let me know. Don't know what stage it is in, but doctors wanted her to undergo chemo a.s.a.p.. All this started out out as a cough and doctor kept telling her it was bronchitis!!! thanks!
