Oncology Flashcards
1
Q
What is cancer
A
- uncontrolled cell proliferation and spread of abnormal cells (malignant, neoplasms, tumor, carinoma)
2
Q
Dysplasia
A
- bad formation
- dysfunctional cells grow
3
Q
Metaplasia
A
- cells grow in the wrong place and grow out of control
4
Q
Hyperplasia
A
- increase in number of cells
5
Q
Tumor:
1. adenoma
2. adenocarcinoma
3. sarcome
A
- non-cancerous
- cancer develops in glandular epithelial cells
- cancer develops in mesenchymal cells (muscle/bone etc)
6
Q
Incidence of cancers
A
- most common diagnosis = breast cancer/prostate cancer
- most commonly causing death = lung cancer
7
Q
Risk factors for cancer
A
- age
- previous cancer
- lifestyle
- viral exposure (Epstein-bar, H-pylori, herpes)
- unsafe sex
- urban air pollution
- smok
- tabaco
- alcohol
- obesity
8
Q
Patters of pain referral
A
- Somatic
- visceral
- neuropathic
9
Q
Somatic pain referrals
- C7-T5
- Shoulder
- L1-L2
- Hip joint
- pharynx
- TMJ:
A
lesion site to referral site
- C7-T5 = inter scapular area/posterior shoulder
- Shoulder = neck/upper back
- L1-L2 = SI joint/hip
- Hip joint = SI and knee
- pharynx = Ips. ear
- TMJ: head, neck and heart
10
Q
Visceral pain referrals:
- diagphragmatic
- heart
- urotherial tract
- pancreas/liver/spleen
- peritoneal/abdominal cavity
A
- diaphragmatic irritation = shoulder/lumbar spin
- heart: above diaphragm
- urotherial tract = back, inguinal region, anterior thigh and genitalia
- pancreas, liver, spleen, gallbladder = shoulder, mid thoracic, low back
- peritoneal or abdominal cavity = hip pain from abscess of poses or obturator muscles
11
Q
Neuropathic pain referral
A
- Nerve or plexus = anywhere in distribution of peripheral nerve
- nerver root = dermatome
- CNS: anywhere in region of body innervated b damaged structure
12
Q
Childhood cancers
A
- Most common malignancies = ALL, non-hodgkin lymphoma, and primary CNS tumors
- neuroblastoma is the most common extra cranial solid tumor in children(mass of cells established in one area)
- rhabdomyosarcoma is the most common soft tissue sarcoma and the seventh leading cause of cancer in children
- incidence peaks between 2-5 years and 15-19 years
13
Q
Prognosis for cancers
A
- varies
- about 65% of all people have 5 year survival rate
- a significantly lower survival rate in African American mean
- modified Barthel index can provide important predictions about the length of time until death
14
Q
Neoplasm ways to classifications and stage
A
- original cell type
- staging system
- the tumor, node, metatases system (TNM)
- variety of systems
15
Q
staging system for classifying and staging neoplasms
A
- specific for each type of cancer
