Hi There,
I think you are asking me about prognosis. It is hard to predict what a particular person's experience will be. Your mother is experiencing some growth of her cancer. It is not necessarily mean that her cancer will be growing more quickly now.
As far as lymph node involvement by cancer, this a common but usually, lymph node involvement does not make a person sick. For women with ovarian cancer, the toughest part is when the cancer in the lining of the abdomen grows. That does cause bowel obstruction. It does not sound like your mother has symptoms of a bowel obstruction right now.
How does the end of life occur? For many women who experience ovarian cancer, there comes a time when it is not possible to eat anymore because of the cancer in the abdomen. this leads to malnutrition, lowering of the immune symptom, swelling and fluid in the legs that makes it hard to get out of bed.
When a person's performance status drops to a 3 or 4 (not getting out of bed), chemotherapy is no longer helpful.
I am sorry.This is rough stuff. It sure does not sound like your mother is at that point.
take care
