The Chorus recounts the events leading to Antigone's tragedy. Oedipus, Antigone and Ismene's father, had two sons, Eteocles and Polynices. Upon Oedipus' death, it was agreed that each would take the throne from one year to the next. After the first year, however, Eteocles, the elder, refused to step down.
Ultraviolet (UV) radiation from the sun is the number-one cause of skin cancer, but UV light from tanning beds is just as harmful. Exposure to sunlight during the winter months puts you at the same risk as exposure during the summertime, because UVA rays are present in daylight.
Cumulative exposure to sunlight causes most cases of squamous cell carcinoma. Frequent use of tanning beds also multiplies the risk of squamous cell carcinoma; people who use tanning beds are 2.5 times more likely to develop squamous cell carcinoma than those who donât. But skin injuries are another important source.
