2. What is cancer?
Cancer is the abnormal proliferation of any of the different kind of cell.
Cancer- Latin word which means “Crab”

3. OncologyStudy of cancer
Onco- Greek word which means Tumor
Tumor
Tumor is uncontrolled growth of cell.

4. Types of Tumors

5. Types of Cancers
On the basis of cell type On the basis of tissue of origin

6. On the basis of cell type

7. On the basis of tissue of
origin
Fibro-sarcoma- in fibroblast
Erythoid leukemia- in RBC

9. Development of Cancer

10. Causes of Cancer
Radiations Chemicals Viruses

11. Tumor Viruses

12. Properties of Cancer Cells
 Less adhesive
 Secrete Proteases
 Angiogenesis
 Fail to undergo Apoptosis
 Loss of Density dependent inhibition
