In many types of cancer they talk about "chemo brain" which represents fatigue and brain fog
and memory issues. Also, the cancers themselves can have tremendous fatigue, especially in
the cancers, such as blood/immune cancers (Lymphoma and Multiple Myeloma) where there is
*anemia* as a major symptom.
There is actually a very real connection between the blood cancers
and ME/CFS . Some people go on from having ME to then also getting these types of cancers.
(Witness the Rituximab crew.....the patients who were treating their Lymphoma and ended up
having ME remissions on that drug.....then now the major study in Britain I think it is.....
with treating regular (non cancer) pts with Rituximab. My belief is that the immune abnormalities
CAN very much so, relate to cancers.
