Abstract:
With increasing local regional control and survival rates, the incidence of distant metastasis is increasing. Head and neck malignancies traditionally metastasize to the lung, liver and bone. We present a case of an elderly woman who was loco-regionally controlled after radiotherapy for carcinoma of the tonsil, but later presented with breast metastasis. To our knowledge, this metastatic pattern has never been reported in published literature. We also discuss the management of breast metastasis and the need to avoid unnecessary mastectomies in such patients.

Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
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...
