Cancer Biology: Hormone Receptor leh HER2 te hi a ni
Awle, tunah chuan tlem han laih thui deuh ila. Hormone therapy hi i tan a tha em tih chu dah bo ila, zawhna lian tak lo awm tur chu chemotherapy i mamawh leh mamawh loh hi a ni.

Oncotype Dx test hi eng nge ni?
I cancer chu HR-positive, HER2-negative a nih chuan, chu chu a chunga table-a type hmasa ber, zawhna "Chemo ka mamawh em?" tih hi chhan harsa ber a ni. Hetiang case-ah hian doctor-te chuan `Oncotype Dx` ang chi genomic test an hmang thin.
He test hian i cancer sample tlemte atanga gene 21 a zirchiang a. Chumi atanga chhut chuan i cancer hian nakin lawka a lo lang leh theihna chance a nei tlem, a hniam emaw, a sang emaw tih hriattirna score a pe che a ni.
