Are there signs if Lyphoma spread? - what is a lyphoma

My sister, 29 years was due to pneumonia in the hospital last week. After X-rays, doctors found a mass of 14 cm in the right lung. The biopsy reports say there is no B-cell lymphoma Hodgekins My sister seems to be a healthy girl who just ran a marathon in New York in November. A month later, he is joint pain and rash, we thought, was on the marathon. She went to the doctor and told him it was an allergy. A month ago, began to suffer chest pain and coughing up blood. My question is, how do you know whether to distribute it? Are there signs? What are the chances of survival?
