Whether following quote can be relevnt to how host defence works on
cancer and other infections in dormacy:
"Iron Loading and Disease Surveillance
Eugene D. Weinberg

Iron is an oxidant as well as a nutrient for invading microbial and
neoplastic cells. Excessive iron in specific tissues and cells (iron
loading) promotes development of infection, neoplasia, cardiomyopathy,
arthropathy, and various endocrine and possibly neurodegenerative
disorders. To contain and detoxify the metal, hosts have evolved an
iron withholding defense system, but the system can be compromised by
numerous factors. An array of behavioral, medical, and immunologic
methods are in place or in development to strengthen iron withholding.
Routine screening for iron loading could provide valuable information
in epidemiologic, diagnostic, prophylactic, and therapeutic studies of
emerging infectious diseases.

Broadly, there may three states, primary, dormant and active in
chronic dormant typediseases as cancer, TB etc. I think, there may be
two types of progression in each state representing fight for survival
betwwen host defence and disease agents. As such one should be
direction towards cure/ treatment(host defence mediated) and other
direction towards progression of disease(disease agent mediated.
Whoever is stronger can wil ultimately. As such, I was willing to
better understand, possible direction towards cure/treatment by host
defence in all three states.
Btw, When host defence recognizes cancer cells & start working?
