<human>: Condense the text into a few key points

Around December 20th, my 43 year old mother began having shortness of breath, and after a week went into the local hospital and had several chest X-rays and CT scans, and the doctors found fluid in her lungs. They drained her lung fluid and sent it to Mayo Clinic, and a biopsy performed January 7th confirmed non-Hodgkin's Lymphoma, large B-cell as well as the test results from Mayo. She began RCHOP chemotherapy and has been getting her lung drained once a week. We are waiting on the test results from her bone marrow test and she has a PET Scan Thursday to determine the stage of cancer she is in.

What I'm asking is, what can she expect for her treatments? The general success rate for treatment is 65%, and that number will change after test results come in. What are other people's experiences personally or with friends or family? What can we expect, and what are some of the best ways to help my mother as she goes through her treatment? Also, as her chemo will eliminate her white blood cells, what are some ways to help keep her healthy?

Thank your for any advice or help you can provide!
