EGFR and cancer: States adopted by signalling plasma membrane receptors, like the EGFR, can typically include monomers, which tend to be structurally and diffusionally more dynamic,1, 2 dimers,3 larger oligomers characterised by stoichiometry, size, geometry, and conformation,4, 5 and larger clusters, possibly underpinned by supra‐molecular interactions, and which are experimentally characterised by the type and number of receptors, their shape and size, and can vary between normal and cancer cells.6
