How the
Incidence of Skin Cancer Depends on the Pattern (short bursts or over
a long period of time) and the Amount of Exposure
This picture
consists of two graphs:
The first
graph shows how the risk of three different skin cancers changes if the
pattern remains constant but the amount of sun you get increases. In all
three cases, melanoma (CMM), basal cell carcinoma (BCC), and squamous
cell carcinoma (SCC), an increase in sun exposure leads to increased incidence
of skin cancer.
The second
graph shows how the risk of different skin cancers changes if the pattern
changes but exposure to UV rays remains the same. The incidence of BCC
and the incidence of CMM increase when the pattern of sun exposure changes
from more continuous to more intermittent, but the incidence of SCC remains
the same regardless of exposure pattern.
