Does anyone know about Thymus Cancer? My mom was recently diagnosed with this after finishing chemo for Follicular Lymphoma. She actually graduated from 6 months of chemo for the Lymphoma and three weeks later she started having swelling on her neck and arm(left side). When she's up walking around she feels light headed and sometimes feels like she wants to pass out. She doesn't do much and actually likes to sleep a lot . I was wondering if anyone had any information on this type of cancer and what I could possibly do with her so she doesn't feel so tired all the time. Any Advise would be appreciated. Thank You so much!!!
