Radiation Oncology/Physical Oncology


 * Physical oncology (PO) is defined as the study of the role of mechanical signals in a cancerous tumor
 * The mechanical signals can be forces, pressures ("pull", "push" and "shear" designating the forces / pressures that push, pull or are tangential)
 * A cancerous tumor (or "solid tumor" in the jargon of oncologists to differentiate them from hematological malignancies) is an organ consisting of two tissues
 * In the center the cancerous tumor proper and around the ExtraCellular Matrix (ECM), sometimes called stroma, chorion or connective tissue
 * The cancerous tissue is derived from a normal tissue of the body: breast cancer arises from a cancerous transformation of the normal mammary glandular tissue
