Oncology - ✔✔ correct answer Branch of medicine dealing with tumors.
Oncology Nursing - ✔✔ correct answer Nurses that care for pts with CA.
Neoplasm - ✔✔ correct answer Neo = New , Plasma = New tissue growth
Cells that produce abnormal .
Neoplasm are tumors but all neoplasm are no CA.
Cancer - ✔✔ correct answer A group of cells that grow out of control, taking over the function of the
affected organ.
Cancer is not 1 disease but many with different causes, manifestations, treatments and prognosis.
Poorly constructed, loosely formed, and disorganized.
"confused cell"
An organ with a cancerous tumor eventually ceases function.
Benign - ✔✔ correct answer A cluster of cells that is not normal to the body but is noncancerous.
Benign tumors grow more slowly than malignant and have cells the same original tissue.
An organ with a benign tumor usually continuous to function normally.
Slow Growth, stays localized, encapsulated, differentiated..
Malignant - ✔✔ correct answer Tumor resist treatment and tends to worsen and threaten life.
Causes some of the same problems as benign, but are more threatening.
They can invade nearby issues or colonized In other parts of the body.

Some of the same problems are benign
dedifferentiated 9stop looking like cells that they took over.
Invades neighboring tissue.

Reoccurrence possible
Fatal without treatment
Cancers cells growth and reproduction involve a 2 step process. - ✔✔ correct answer 1. Initiation
Causes an alteration in genetic structure of the cell (DNA).
Cell alteration is associated with exposure to a carcinogen. The cellular change primes the cell to become
cancerous.
2. Promotion
The second step in cancer cell growth.
It occurs after repeated exposure to carcinogens causing cells to mutate. During this step a tumor forms
from mutated cell production.
A healthy immune system can destroy cancer cells before they replicate and become a tumor.
Any substance that weakens or alters the immune system puts the individual at risk for cell mutation.
Caner is a symptom of a weakened immune system.
Carcinogen - ✔✔ correct answer A substance or agent that increases the risk of cancer.
Risk Factors for Cancer - ✔✔ correct answer Exposure to radiation, chemicals, irritants, genetics, diet,
hormones and general immunity. Certain racial and ethnic groups also are at higher risk for some type of
cancer.
Risk Factor: Viruses - ✔✔ correct answer Oncoviruses (onco - mass + virus)
(RNA type viruses) are linked to cancer in humans.
Retrovirus
An enzyme produced by RNA tumor viruses and is formed in human leukemia cells.
