Step-by-step explanation:
The specific number of Mayo definitions for the term cancer is not listed in the provided content. However, it is important to note that cancer is a broad term for a group of diseases characterized by abnormal cell growth with the potential to invade or spread to other parts of the body. Key characteristics of cancer include unregulated cell cycle due to DNA damage, rapidly dividing cells, mass formation called a tumor, and potential to cause serious harm or death if cells spread, a process known as metastasis.
The referenced materials mention several types of cancers such as pancreatic, brain tumors, breast, cervical, prostate, lymphoma, colorectal, kidney, lung cancer, melanoma, neuroblastoma, acute myeloid leukemia, multiple myeloma, and non-Hodgkin's lymphoma. These materials also address aspects like carcinogens, metastatic mechanisms, and the significance of multiple mutations occurring for cancer to develop.
