NCIt definition : The estrogen receptor level measured in a primary tumor or in metastases. There are
essentially two distinct forms of breast cancer, one that tends to have an early onset
and is characterized by an ER- status, and one that tends to have a late onset and
is characterized by an ER status. However, these two variants tend to overlap with
respect to age, so it is possible for a young woman to have a late-onset form of breast
cancer and for an older woman to have an early-onset variant of the disease.;
