Neoplasia

2. Process of new growth in which normal cells undergo irreversible genetic change
9. abnormal numbers of chromosomes
11. Benign tumor of adipocytes
12. tissue growth
18. extreme variability in nuclear size
19. wide variation in cell siza
20. growth factor that stimulates fibroblast and increase production of collagen
21. tumors spread beyond the original host via physical transplantation following direct physical contact between animals of the same species
23. ovarian and pancreatic adenocarcinomas spread transcoelomically, resulting in multiple tumor masses throughout the abdomen
25. process by which the immune system identifies and kills microbially infected cells or foreign cells

1. wide variation in cell shape
3. an irreversible alteration of genetic material, first step of neoplastic transformation
4. antigens antigens present on both tumor cells and normal cells
5. Development of new blood vessels
6. spread Tumor invade through veins to reach the vena cava, commonly sarcomas
7. antigens antigens restricted to tumor cells
8. cancerous tumors that invade locally and spread by metastasis
10. outgrowth of initiated cells in response to selective stimuli, second step of neoplastic transformation
13. nonneoplastic supporting structures like blood vessels, fibroblast, and inflammatory cells
14. antigens embryonic antigens normally not expressed in adult tissue
15. noncancerous tumors that do not invade locally nor spread
16. malignant transformation, third step of neoplastic transformation
17. development of lymphatic vasculature in tumors
22. tumor consisting of tumor cells termed parenchyma
24. notable weight loss and debility
26. poor cell differentiation
