18
Q

A

biopsy of lymph node

19
Q

When does a lymph node need to be biopsied?

A

> 1 cm
not related to infection
present > 4 - 6 weeks

20
Q

Lymphoma stage 1 is:

A

localized to single lymph node or group

21
Q

Lymphoma stage 2 is:

A

confined to ONE SIDE of the DIAPHRAGM

22
Q

Lymphoma stage 3:

A

occurs on BOTH SIDES of the DIAPHRAGM

23
Q

Lymphoma stage 4 is:

A

really bad

liver or bone marrow involvement

24
Q

What age adult is typically affected by lymphoma?

A

the younger adult

25
Q

What are the two types lymphoma? Which is more predictable?

A

Non-Hodgkin’s Lymphoma
Hodgkin’s Lymphoma

Hodgkin’s is more predictable

26
Q

What is a common initial presentation of Non-Hodgkin’s Lymphoma?

A

lymphadenopathy

27
Q

Predictable or unpredictable pattern of spread?

less predictable than Hodgkin’s

A

lymphoma

31
Q

What does the management of lymphoma include?

A

Radiation
chemotherapy
bone marrow transplantation

32
Q

What is the TNM tumor classification system?

A

T for tumor size - 0 to 4
N for lymph node involvement - 0 to 3
M for distant metastasis 0 or 1

worst is T4, N3, M1
