What are the 3 steps to carcinogenesis

Initiation- exposed to carcinogen

Promotion- neoplasm; mutates

Progression- ⬆️mutation; ⬆️growth; clinical dz

5

Neoplasia

Process of uncontrollable cell growth/formation of tissue mass

6

Benign

Slow growing and harmless

7

Malignant

Fast growing, metastasizes

8

What regulates tumor growth?

Host immune system

Adequacy of blood supply/nutrients

Hormonal/growth factors

9

Metastasis

Invade surrounding tissues

10

3 paths tumors metastasize

Lymphatic- through lymph nodes

Hematogenous- through blood stream

Transcolelomic- direct seeding; across body cavities

11

What are Carcinogens? Examples?

Cancer causing agents; genetic defect, radiation, diet, hormones
