The terms used to describe cancer in word list; L
Leiomyosarcoma, a malignant tumour featuring differentiated smooth muscle cells, is rare in the oesophagus. In a recent series, such tumours comprised 4% of all combined smooth muscle and stromal tumours. They were large tumours that presented in older adults, and all patients died of disease.
Liposomal therapy; is a new technique that uses chemotherapy drugs that have been packaged inside liposomes (synthetic fat globules). This liposome, or fatty coating, helps them penetrate the cancer cells more selectively and decreases possible side effects (such as hair loss, nausea, and vomiting). Examples of liposomal medications are Doxil (the encapsulated form of doxorubicin) and Daunoxome (the encapsulated form of daunorubicin).
Lobular Carcinoma In Situ (LCIS). Cells that are not normal but that stay inside the milk-making part of the breast.
Louis Leakey; found the oldest possible hominid malignant tumor in 1932 from the remains of either a Homo erectus or an Australopithecus. This tumor was suggestive of a Burkitt’s lymphoma (although that nomenclature was certainly not in use then). Diseases that we know to be rare cancers today have had a long history.
Lymphatic invasion; means that cancer cells are found in the lymph vessels.
Lymph nodes. Filters along the lymph fluid channels; they try to catch and trap cancer cells before they reach other parts of the body.
Lymphangioma. is a benign tumour characterized by multiple endothelial-lined spaces that vary in size from capillary channels to large, cystic spaces containing lymph. The vascular spaces are lined by a single layer of endothelial cells, though papillary projections or tufting may be seen.
