Aberrant expression of E-cadherin has been associated with the development of metastases in patients with breast cancer. A staining result was considered to be positive for ALDH1 and pAKT if the H-score was higher than the reference staining of non-malignant breast tissue, which served as a control. The term "aberrant breast tissue" is defined as "an island of breast tissue usually located in proximity to the normal breast" [ 4 ].

The nodule is usually sessile; it may be lobulated and present a granular surface. Aberrant SRPK1 expression is implicated in various signalling pathways associated with oncogenesis, a number of which, such as the PI3K/AKT, NF-КB and TGF-Beta pathway, are implicated in multiple dierent . There is not a time frame in which the Member is required to have the reconstruction done post Mastectomy under the Women's Health and Cancer Rights Act of 1998.
