Unit 13 Cancer Screening Flashcards
What is Cancer?
What is a Tumor?
Cancer is the name given to a collection of related diseases. In all types of cancer, some of the body cells begin to divde without stopping and spreading to surrounding tissues
When cells become abnormal, old or damaged and they survive when they should die and new cells form without needing to. These extra cells can divide without stopping and may form growths called tumors
What does it mean that Cancerous tumors are malignant?
This means they can spread into or invade nearby tissues
What are some Non-Modifiable Cancer Risk Factors?
- Age
- Inheritied
- Family Hx
- Associated with congenital disease or autoimmune diseases
What are some Modifiable Cancer Risk Factors?
- Smoking
- Alcohol
- Radiation
- Obesity
- Lack of B12
- Lack of education
- Smoked foods, red meat, cold meat cuts, salty fish
What are the 4 Major Cancer Types?
- Carcinomas (80 to 90% of all cancers)
- Sarcomas
- Lymphomas
- Leukemias
Cancer Types
With Carcinomas, where do these cell types originate?
Arise from Epithelial Cells
- Breast (1st) (Ductal or Lubular carcinoma)
- Lung (2nd)
- Prostate (3rd)
- Colon/Rectal (4th)
- Skin (5th) (Basal Cell Carcinoma, Melanoma)
Cancar Types
With Sarcomas, where do these cell types originate?
Develope from Connective Tissue
- Muscle (Rhabdomyosarcoma)
- Bone (Osteosarcoma)
- Cartilage (Chondrosarcoma)
Metastasize Hematogenously
Cancer Types
With Lymphomas, where do these cell types originate?
Originate in Lymphoid Tissues (Hodkins and Non-Hodgkin Lymphomas
- Lymph Nodes
- Spleen
- Intestinal Lining
Spread by Infiltration
Cancer Types
With Leukemias, where do these cells types originate?
Cancers of the Hematologic System
- Bone Marrow (Myeloma); Invasion and infiltration
What are the Early Signs of Cancer?
“CAUTIONS”
- Changes in bowl and bladder habits
- A sore that does not heal in 6 weeks
- Unusual bleeding or discharge
- Thickening or lump in breast or elsewhere
- Indigestion or difficulty in swallowing
- Obvious change in a wart or mole
- Nagging cough or hoarseness
- Supplemetal s/s (rapid unintensional weight loss, changes in vital signs, frequent infections, night pain, proximal M. weakness, changes in DTRs)
Also,
- If patient does not improve with PT treatment
What are Early Signs of Cancer that the PT can observe?
- Changes in Vital Signs
- Proximal Muscle Weakness
(Troubke climbing stairs, getting up from sitting, positive trendelenburg, SOB) - Changes in DTRs
(Decreasesd or absent due to compression by tumors)
What systems should we observe for S/S of Cancer?
- Integumentary
- Pulmonary
- Neurologic
- MSK
- Hepatic
When screening the Integumentary system for cancer, what s/s should we look for?
- Skin and nail bed lesions
- Unusual mole
- Bleeding or discharge from mole, skin lesion, scar, or nipple
- Sores that dont heal
- Nail bed changes (Clubbing, can be lung Cx; Splinter hemorrhages, can be hematologic Cx)
When screening the Pulmonary system for cancer, what s/s should we look for?
- Pleural Pain
- Dyspnea
- Noew onset of wheezing
- Productive cough with rust, green, or yellow-tinged sputum
When screening the Neurologic system for cancer, what s/s should we look for?
- Changes in bowl and bladder function (cauda equina syndrome, saddle anesthesia, LE weakness)
- Changes in DTRs
- (+) Babinski reflex
- Clonus
- Balance/coordination problems
