I have included a link that gives you a diagram. If it has travel to a different location away from the primary sites like liver , lung or distant lymph node spread ( not lymph nodes near the primary tumour) it’s diagnosis as stage 4 and that is recorded under the capital M . No spread would be M0 , a spread may be recorded as M1.
Hope that helps and many people wonder about that one !
They would have told you if it had spread ! They are very honest about it . They don’t sugar coat it so I really think they would have said . Your specialist nurse could reassure you if your at all worried !
