Comment:

Answer D

T1 disease is not palpable or visible with imaging, non-regional (extrapelvic) lymph node involvement is classified M1a. Tumour involving but not penetrating through the capsule is pT2 (p denotes ‘pathological’). Tumour found in both lobes by needle biopsy, but not palpable or visible by imaging, is classified as T1c.
