I am a cancer doctor.
I am sorry about your wife's situation.
what chemotherapy agents is she getting?
what type of cancer does she have?
is she drinking enough fluids?
Rituximab , Doxoubicin , vincrishre? , ctclophosphamide ,
sounds like she is battling a lymphoma.
Lymp cancer and bone marrow and is drinking 2ltr of water per day .
she needs to see a doctor right away about this difficulty in urinating.
this could be due to a blockage of the kidneys from enlarged abdominal lymph nodes.
it could be due to kidney failure.
it could be due to cancer spread to the spinal cord causing spinal cord compression and neurogenic bladder dysfunction.
there are many potential causes.
she needs to be seen at the emergency room right away
or call her cancer doctors right away.
