Hi
My sister's cancer symptoms are cancer cells that are showing up in her lymph glands in her neck and chest, causing them to swell. Doctors have been unable to determine the source of the cancer cells. She's been on chemo for several months, during which time her symptoms have been stable. In the past week, the lymph glands in her neck started to swell and are now quite painful.
What are the likely causes for this to happen? Does this mean the cancer is winning, or perhaps that doctors varied the type of chemo they gave her in her most recent treatment?
