Cancer Flashcards
Does not spread
Benign
Encapsulated
Doesn’t spread
Me stashed to other parts of the body
Malignant
Most important risk factor to skin cancer
Overexposure to uv radiation
Gradually forms an ulcer with firm raised border
Squamous cell
How many people in America develop skin cancer
1 in 5
Metastasizes rapidly to lymph and blood vessels
Melanoma
Other ways you can develop skin cancer
Irritation from infection
Chemicals
Physical trauma
How large must the diameter be for it be melanoma
6 mm
Arises from stratum spinosum
Squamous cell
Arises from stratum basale
Basal cell
What percent of basal cell is cured
99%
Grows quickly and metastasizes to lymph nodes if not removed
Squamous cell
Slow growing, metastasis seldom occurs
Basal cell
What cause squamous cell
Sun
Scaly reddened Papule
Squamous cell
By age fifty how many hair follicles does a person have
Dropped by 1/3 and continues to decline which leads to thinning or baldness
Most common type of cancer
Skin
Cancer of melanocytes
Malignant melanoma
Small rounded elevation
Papule
What percent of skin cancers are melanoma
5
Shiny dome shaped nodules with a central pearly beaded edge
Basal cell
Most deadly
Melanoma
What causes bags under the eyes
Decreasing elasticity and loss of subcutaneous tissue
C
Color
During old age what happens to the amount of subcutaneous tissue
Decreased which leads to intolerance of cold
What is survival rate of melanoma
Fifty percent
Where is basal cell normally found
Overexposed regions of face
Where does melanoma begin
Wherever there is pigment
Some develop from pigmented moles
Arises from accumulated dna damage in skin cell and appears as spreading brown to black patch
Melanoma
A
Asymmetry
Early removal allows a good chance of survival
Squamous cell
B
Border irregularity
Where is squamous cell most likely found
Scalp ears and lower lip
What is the treatment of melanoma

Tiny colorless hairs on bald people
What helps delay skin aging

Plenty of fluids
Cleanliness
Male pattern baldness
Genetically controlled
Graying hair is genetically controlled by what
Delayed action gene
Abnormal cell mass
Neoplasm
Gray hair occurs when
Amount of melanin in hair decreases or becomes absent
Least malignant
