Ductal carcinoma in situ (DCIS) is a noninvasive type of breast cancer that starts in the lining of the breast ducts (the tubes that carry milk). Noninvasive means that all the cancer cells are confined to the ducts and glands. They have not broken through the duct wall into nearby breast tissue. Because the cells are …

Burkitt lymphoma is a rapidly growing cancer of the immune system that originates from B cells, a type of white blood cell that normally helps fight infections. This lymphoma is unique because it is almost always associated with a genetic mutation in the MYC gene, which causes the cancer cells to divide rapidly. Due to …
