AP BIOLOGY

Detailed explanation-1: -They occur from damage to genes in a particular cell during a person’s life. For example, this could be a breast cell or a colon cell, which then goes on to divide many times and form a tumor. A tumor is an abnormal mass. Cancer that occurs because of acquired mutations is called sporadic cancer.

Detailed explanation-2: -When cells grow old or become damaged, they die, and new cells take their place. Sometimes this orderly process breaks down, and abnormal or damaged cells grow and multiply when they shouldn’t. These cells may form tumors, which are lumps of tissue.

Detailed explanation-3: -Neoplasia denotes the process of the formation of neoplasms/tumors, and the process is referred to as a neoplastic process.

Detailed explanation-4: -In adults, the type of cell that becomes cancerous is usually an epithelial cell. Epithelial cells line the body cavity and cover the body surface. Cancer occurs from environmental exposures to these cells over time.

Detailed explanation-5: -Cancers are caused by damage to the DNA in your cells. These changes are called “gene mutations.” Gene mutations can build up in cells in your body over time. Cells with too many mutations may stop working normally, grow out of control and become cancerous.
