Although it was not revealed at the time, first lady Laura Bush was diagnosed with squamous cell carcinoma in October, and underwent a surgical procedure to have the cancerous tumor removed from her shin shortly before the elections on November 7th. When the first lady's press secretary Susan Whitson was asked why the information about Mrs. Bush's cancer diagnosis was withheld from the public, she responded by saying, "This medical procedure was a private matter for Mrs. Bush, but when asked by the media today, we answered the question."

In 2001, President Bush had four suspicious facial lesions surgically removed that can lead to cancer if left untreated. At the time, they had not progressed into cancer.

Mrs. Bush is reported to be doing well, and is optimistic that the cancer was discovered early.

According to the MedlinePlus Medical Encyclopedia, squamous cell skin cancer is a type of tumor that affects the middle layer of the skin. Over 90 percent of skin cancers occur on areas of the skin that are regularly exposed to sunlight or other ultraviolet radiation. Squamous cell cancer is a malignancy that is more aggressive than basal cell cancer, but still may be relatively slow-growing.
