Abstract:
Atypical ductal hyperplasia (ADH) as an indicator of increased risk for developing breast cancer is well established. Refinement in its molecular characterisation, especially as it relates to risk, continues to be challenging, largely because of its small and very focal nature. Also a challenge is appropriate management of ADH when present on core biopsy. Additional support for ductal carcinoma in situ (DCIS) as a precursor to invasive cancer, as well as recent molecular characterisation of DCIS are presented. The importance of margin assessment in cases of DCIS and the limited role for sentinel lymph node biopsy in this setting are reviewed.

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
