Investigating the effect of inflammation on the progression of B-cell lymphoma dissemination in the sentinel lymph node

Daniel Molina Romero

Lymphomas are a group of heterogeneous blood cancers that arise from lymphocytes. The two primary clinical classifications of lymphomas are Hodgkin's lymphoma (HL), and non-Hodgkin's lymphoma (NHL). In particular, B-cell lymphoma refers to the malignancies ...

Metabolic dependencies of metastasis-initiating cells in breast cancer

Candice Megan T Young

Metastasis is the process by which cancer cells from the primary tumor travel through the blood stream to generate a secondary tumor site in a distant organ. Although very few cells are able to make this journey, the resulting effects are dire since most c ...
