Other Skin Cancers

Basal-cell carcinoma may have slightly raised edges with a crusty, indented center.

Basal-cell Carcinoma

What it is:

  • It is the most common type of skin cancer in fair-skinned people.
  • It is more common than all other cancers combined.
  • It is estimated that 1 in 5 Americans will develop a basal-cell carcinoma in their lifetime.1
  • It is very strongly associated¬†with chronic sun exposure or sun tanning.
  • It usually shows up on the face, ears, scalp, neck, or upper body.

 

Signs:

  • A red patch
  • A pink, red, or white bump that is shiny or pearly
  • A crusty, open sore that will not heal
  • A scar-like area
  • It grows very slowly and usually does not spread to other parts of the body
  • It is usually removed with surgery or by freezing the tumor (cryotherapy)

Squamous-cell Carcinoma

Squamous-cell Carcinoma

What it is:

  • It is the second-most-common type of skin cancer in fair-skinned people.
  • An estimated 200,000 squamous-cell carcinomas occur each year.2
  • It is twice as likely to occur in men as in women.
  • It usually appears on the face, neck, arms, scalp, ear, lips, or mouth.
  • Like other skin cancers, it is caused by excessive exposure to UV rays from the sun or indoor tanning booths.

Signs:

  • A bump or scaly red patch
  • A slow-growing cancer
  • Can spread to other parts of the body; thus, it is important to treat it as early as possible through surgery or radiation therapy
  • When on lips, it is associated with smoking or using chewing tobacco and has a much higher rate of spreading to other parts of the body
