What are the 4 abnormal skin changes with aging?

2) basal cell/rodent cell (malignant)
3) squamous cell (malignant)
4) malignant melanoma
actinic=
light
Which skin abnormality is used to describe pre-cancerous?
actinic keratosis
Which abnormal skin change is this?
-repeated exposure to UV light
-overtime the skin cells come irreparably
-damaged, superficial flattened papules covered by a dry scale
-may be blotch looking and multiple lesions
-benign, at first, but may advance to squamous cell carcinoma
actinic keratosis
What is the most common type of skin cancer?
basal cell carcinoma/rodent cell carcinoma
Which abnormal skin change is this?
-slow growing skin cancer that rarely metastasizes
-translucent at first with a depressed center
-sore that does not heal
-more common in males, more intermittent UV exposure
basal cell carcinoma/rodent cell carcinoma
What is the 2nd most common type of skin cancer?
squamous cell carcinoma
Which abnormal skin change is this?
-faster growing than basal cell carcinoma
-starts as whitish, flaky skin which reddens with ulceration
-may develop from actinic keratosis
-more chronic and cumulative exposure
-can metastasize
squamous cell carcinoma
What is the difference between basal cell carcinoma and squamous cell carcinoma?
What are the risk factors for basal cell carcinoma and squamous cell carcinoma?
-over 50 y/o
-skin doesn’t tan well or previous bad sunburns
-exposure to coal, tar, creosote, arsenic, petroleum products
-living around the equator or at high altitudes
-overexposure to xrays
