18
Q

what is differentiation

A

how it looks compared to normal cells both in structure and function.

19
Q

what is anaplasia

A

is a state where tumor cells lack differentiation

20
Q

what is pleomorphism

A

cells and nuclie are variable in size and shape

21
Q

what are the characteristics abnormal nuclear structure

A

nuclie will have an abundance of DNA and are hyperchormoatic

22
Q

what is different in anaplasia with mitosis

A

a large number of mitotic spindsl and may be tripolar or quadpolar

23
Q

what happends to polarity in anaplasia

A

it can be lost so the cells lose organization

24
Q

what does it mean to be in situ with a cancer

A

that it has not yet left the basement membrane or the area where its supposed to be.

25
Q

what is direct seeding of cavities or surfaces of a malignent tumor

A

when it directly invades the cells next to to.

26
Q

what is hematogenous

A

when the malignant tumor is spread through the blood vessels common in liver and lungs due to volume of blood flow

27
Q

what is perineural invasion and spread

A

when the cancer invades the ct coat of nerves and travel around the nerve, common in head, neck prostate and pancrease cancers and can generate pain.

A

squamous cell carcinoma with pearls found in smokers and men, adenocarcinoma most common in women and non smokers. Small cell carcinoma highly malignant, large cell carcinoma undifferentiated.

43
