Neoplasia

3. wide variation in cell shape
8. Benign tumor of adipocytes
10. malignant transformation, third step of neoplastic transformation
12. growth factor that stimulates fibroblast and increase production of collagen
13. ovarian and pancreatic adenocarcinomas spread transcoelomically, resulting in multiple tumor masses throughout the abdomen
14. spread Tumor invade through veins to reach the vena cava, commonly sarcomas
17. cancerous tumors that invade locally and spread by metastasis
19. notable weight loss and debility
20. noncancerous tumors that do not invade locally nor spread
21. Process of new growth in which normal cells undergo irreversible genetic change
22. tissue growth
23. antigens embryonic antigens normally not expressed in adult tissue
24. abnormal numbers of chromosomes
25. poor cell differentiation

1. antigens antigens present on both tumor cells and normal cells
2. antigens antigens restricted to tumor cells
4. development of lymphatic vasculature in tumors
5. an irreversible alteration of genetic material, first step of neoplastic transformation
6. tumors spread beyond the original host via physical transplantation following direct physical contact between animals of the same species
7. extreme variability in nuclear size
9. wide variation in cell size
11. process by which the immune system identifies and kills microbially infected cells or foreign cells
12. outgrowth of initiated cells in response to selective stimuli, second step of neoplastic transformation
15. nonneoplastic supporting structures like blood vessels, fibroblast, and inflammatory cells
16. tumor consisting of tumor cells termed parenchyma
18. Development of new blood vessels
