does not spread
controlled growth rate
smaller cell nucleus
non-cancerous

chromosomal abnormalities

grading system for cellular characteristics - Answer-Grading addresses how malignant a
tumor is. The more aggressive and less similarity to the tissue of origin, the higher the
grade.
The higher the grade, the poorer the outcome
Gx:
grade not determined

G1:
well differentiated
low grade of malignant change
malignant and strong growing

G2:
more moderately differentiated

G3:
poorly differentiated
few normal characteristics

G4:
no normal characteristics
finding tissue of origin is nearly impossible

What is the nurse's role in surgery for patient's with cancer? - Answer-Coordinate care
Encourage patient to express their feelings
Encourage patient to look at and touch the operative site
Encourage patient to participate in care ( ex: wound dressings)
Provide support group contact for patients and families
Have some who has coped with the same issue come for a visit
Referral to a mental health care provider may be needed if the patient has persistent
depression
Develop exercise regimes to maintain strength and function

explain how radiation works for patients with cancer - Answer-Given over multiple
doses/days
Directed at the tumor to kill or halt mitosis of tumor cells

TELETHERAPY:
Radiation is delivered from outside the patient so the patient is not radioactive

BRACHYTHERAPY:
Radiation is delivered from within the patient therefore the patient is radioactive

UNSEALED isotopes are given IV or PO and the patient is radio active until the isotope
is eliminated. Excreta is radioactive.

SEALED isotopes are solids implanted in or near the cancer. The patient emits radio
waves but excreta is not radioactive. Implants may be left in permanently or for short
prescribed time periods.
