Cancer Flashcards
3 tumor cell types
-Benign-Differentiated - not cancerous
- In situ- “in position” or “in place.”
* An early stage in which the cancerous, cells remain in the original site
-Malignant-Invades surrounding and distant tissues
Tumor Classification type: solid tumor or liquid tumor
-Solid tumors begin in a solid structure such as bone, muscle, or organ and include carcinoma and sarcoma.
-Liquid tumors are also known as blood cancers or hematological tumors
Solid Tumors
-Carcinoma
Tumors that arise in epithelial tissues 80% to 90%
Sarcoma
- Tumors that arise in supportive and connective tissues
Myeloma
- Malignant tumor that originates in the plasma cells of bone marrow
Leukemia
- cancer that begins when the blood-forming cells create an excess of abnormal (WBC)
Lymphoma
- Develops in the glands or nodes of the lymphatic system causing abnormal cellular reproduction of WBC called
lymphocytes, which are a vital part of the immune system
Mixed-type cancer
-Cancer that has different tissue types or components from more than one type of cancer
Solid tumor stages
TNM
T size of tumor
N nearby lymph node involvement
M presence of metastasis
Overall Stage: I through IV; A & B
III / IV higher cancer stages; poorer prognosis
Cancer stages
Stage 0: carcinoma in situ; early in development, not all cancers
have stage 0
* Stage I: localized cancer; often has a good prognosis
* Stage II and III: locally advanced; criteria for II and III dependent on
type of cancer
* Stage IV: metastasized; cells have become undifferentiated
Classification / staging of liquid tumor or blood cancers
Lymphoma
Lymphoblasts
-Immature blood cells in the bone marrow
-B or T lymphocytes
Myeloma
-Myeloblasts
-Immature blood cells in the bone marrow
-Develop into granulocytes
Leukemia
-Acute or Chronic
Cancer Etiology
Disease of the genes; DNA / RNA
* Uncontrollable cell division
* Cancer is attributed to :
* Genetic inheritance, environmental carcinogens, and lifestyle choices
-diet
-uv exposure
-activity
Cancer Incidence and Prevalence
Survivorship: begins at time of dx and continues through person’s end life
* 14.5 million survivors in US (2015)
* Cancer risk: 1:2 men / 1:3 women
* Most common types: prostate, lung, and breast
Males 4x greater than younger ages
Females 2x greater thane younger ages
Adolescent / Young Adult (B – 14yrs)
Cancer Incidence and Prevalence
10,380 childhood new cases in US (2015)
~ 1,250 childhood deaths
Leukemia 25%
Brain and other central nervous system tumors represent 24%
Cancer Signs and Symptoms
Depends on size and location of cancer
* Whether the cancer is affecting nearby tissues or organs
* Unexplained weight loss
* Persistent headaches
* Persistent low-grade fever
* Repeated infections
* Chronic pain
CAUTION
Change in bowel / bladder habits
A sore that does not heal
Unusual bleeding / discharge
Thickening / lump
Indigestion / difficulty swallowing
Obvious change in a wart, mole, mouth sore
Nagging cough / hoarseness
Cancer Course and Prognosis
2nd leading cause of death; heart disease 1st
* Quality of life is highly impacted
* Five-year survival rates
Cancer Impact on Occupational Performance
Strength / endurance to preform grooming / bathing
* Eating habits
* Pain management
* Sleep cycle
* Meal preparation
* Employment
interventions
Multidisciplinary approach to pain management.
* Interventions include
* Patient education
* Training in proactive pain management
* Safe body mechanics
* Neuromuscular re-education
* Muscle tension reduction training
* Pacing activities
Additional Medical Complications and Considerations
Pain
* Compromised Bone
* Cancer-related fatigue (CRF)
* Cancer-Related Cognitive Dysfunction
* Immobility
* Lymphedema
* Psychosocial Disruption
* Cardiovascular Considerations
