Tumor cell: Receptors: are not on all tumors, and are checked for estrogen (er); Progesterone (pr) and now her-2-neu. If er and pr +, anti-estrogens are of some benefit. They cause tumor cells to stop dividing, and tumors to shrink. They are variable in ductal cancers, but very commonly positive in lobular carcinoma.
