Poorly differentiated neuroendocrine carcinoma (NEC) is a rare and aggressive type of stomach cancer. It develops from specialized neuroendocrine cells found in the lining of the stomach. These cells normally help regulate digestive functions by releasing small hormone-like molecules. In NEC, these cells become cancerous and divide quickly, often forming a large tumor that can …

Adult T-cell leukemia/lymphoma (ATLL) is a rare type of blood cancer that develops from T cells, a type of white blood cell that helps the immune system fight infection and regulate immune responses. When ATLL mainly affects the blood and bone marrow, it behaves like a leukemia. When it grows as a solid mass in …
