Antigen presenting cells have the ability to phagocytose and express antigen on their surface to facilitate the formation of antibodies.

Surveillance immunity refers to the lymphocytes that are responsible for monitoring or controlling cell mutations or uncontrolled growth due to genetic mutations.

Neoplastic cells express histocompatibility complexes on their surface that make them recognized by these lymphocytes and this is how they are responsible for inducing self-destruction or phagocytosis of the neoplastic cell.

Humoral immunity refers to the chemical substances that function as mediators of cell activity, these are: pro and anti-inflammatory cytokines, complement chain, nitric and nitrous acid, oxygen free radicals, interleukins, growth factors and tumor necrotic factor alpha - beta
