along the nuclear membrane, more darkly
stained than normal(hyperchromatic).
iv. Nucleoli ---Abnormally large
Mitoses---reflect the high proliferative activity
of the parenchymal cells.
Morphologic feature of malignancy--- atypical,
bizarre mitotic figures, (tripolar, quadripolar,
or multipolar spindles)

tumor cells grow in an anarchic, disorganized
fashion

.

Alcoholic cirrhosis,
Hepatocellular carcinoma
Diet
Colorectal carcinoma
Obesity.
Obesity
Breast carcinoma
Endometrial carcinoma
Reproductive history:
--- lifelong cumulative exposure to estrogen
stimulation, particularly if unopposed by
progesterone, increases the risk of cancers of
the breast and endometrium,
Environmental carcinogens—
ultraviolet [UV] rays,
smog,
Well water (e.g., arsenic)
medications (e.g., methotrexate)
 The common neoplasms of infancy and
childhood
 Neuroblastoma,
 Wilms tumor,
 Retinoblastoma,
 Acute leukemias
 Rhabdomyosarcomas.
 The rising incidence of cancer with age is
likely explained by the accumulation of
somatic mutations associated with
 Chronic
inflammations
Helicobacter pylori)
gastritis
stomach CA
Immunodeficiency states.
lymphomas
Precursor lesions
 Precursor lesions
 Barrett esophagus (gastric and colonic metaplasia of the
esophageal mucosa in the setting of gastric reflux)
 Squamous metaplasia of the bronchial mucosa (in
response to smoking)
 Bladder mucosal metaplasia (in response to
schistosomiasis infection)
 Colonic metaplasia of the stomach (in the setting of
pernicious anemia and chronic atrophic gastritis)
 Endometrial hyperplasia, which is caused by sustained
estrogenic stimulation of the endometrium.
 Leukoplakia---squamous carcinoma.
 Germline mutations in a tumor suppressor
gene—breast cancer risk in females who
inherit mutated copies of the BRCA1 or
BRCA2 tumor suppressor genes is almost
threefold higher.
