Flashcards in Chapter 21A Terms Deck (18):
1

Substances that causes cancer.

Carcinogens

2

Abnormal mass of tissue arising from an abnormal proliferation of cells.

Neoplasm

3

To spread from one part of the body to another part not directly connected to the first part. Cancerous tumors do this and form new tumors in distant parts of the body.

Metastasis

3

A neoplasm. An abnormal growth of cells. They form from the new growth of tissue in which cell division is uncontrolled and progressive.

Tumor

4

A broad goup of diseases involving unregulated cell growth. (web)

Cancer

5

A gene that has the potential to cause cancer. (web)

Oncogenes

6

The process of programmed cell death. (web)

Apoptosis

8

The changes in shape, nuclei, or organization of adult cells. It is typical of precancerous cells.

Dysplasia

9

A normal gene that can become an oncogene due to mutations or increased expression.

Proto-Oncogenese

10

Early form of cancer that is defined by the absence of invasion of tumor cells into the surrounding tissue. (web)

Carcinoma in situ

11

Any additional sites where the cancer has spread. (web)

Secondary Tumor

12

The creation of cancer, normal cells are transferred into cancer cells. (web)

Carcinogenesis

13

The likely course of a disease or aliment. (web)

Prognosis

14

Drugs which inhibits or prevents the function of cells. (web)

Cytotoxic Drugs

15

A cancerous tumor. An abnormal mass of tissue with cells that can invade surrounding tissue and spread to multiple locations throughout the body.

Malignant Tumor

16

An abnormal mass of tissue that usually remains at the site where it forms.

Benign Tumor

17

Protein in humans which is encoded by TP53, functions as a tumor suppressor preventing cancer. (web)

P53

18

A gene that codes for a protein that suppresses cancer in its normal, healthy form.
