If there is a palpable mass, it is 32% and 31% respectively, with adjuvant chemotherapy (40% and 35%).[15] Positive lymph-nodes have been positively associated with a palpable mass and affect the prognosis to be now just 28% survival after 10 years (vs 79% without palpable mass and without affected lymph-nodes).[15] Involvement of the lymph nodes does not directly cause any harm, but is merely an indicator of systemic spread.[16]
