Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
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...

01:19Ascites
DefinitionAscites is the buildup of fluid inside the peritoneal cavity. It occurs when fluid moves out of the vascular system faster than the peritoneal lymphatics can remove it. This fluid shift is most commonly seen in liver cirrhosis but can also appear in several other systemic disorders.EtiologyCirrhosis remains the leading cause of ascites. Other conditions that can contribute include:Heart failureConstrictive pericarditisAbdominal cancersNephrotic syndromeSevere protein–calorie...
