Skin Cancer Q&A

What is basal cell carcinoma and what does it look like?

Basal cell carcinoma is the most common form of skin cancer. According to the American Cancer Society, over 4 million cases of basal cell carcinoma are diagnosed in the United States every year.

This type of skin cancer almost never spreads beyond the original tumor, but that doesn’t mean it can’t. In rare cases, basal cell carcinoma can spread to other parts of your body and become life-threatening.

Basal cell carcinomas occur in the deepest layer of your epidermis and usually appear as one of the following:

  • Open sores
  • Red patches
  • Shiny bumps or scars
  • Pink growths

What is squamous cell carcinoma and what does it look like?

Squamous cell carcinoma is the second most common form of skin cancer, with over one million new cases diagnosed in the United States every year. This disease kills an estimated 8,800 Americans each year.

This type of skin cancer affects squamous cells in the upper layers of your epidermis and can occur anywhere on your body, including genitals and mucous membranes. It’s most likely to happen in areas exposed to the sun, such as:

  • Rim of the ear
  • Lower lip
  • Neck
  • Hands
  • Balding scalp
  • Arms and legs


Squamous cell carcinomas can be disfiguring and possibly life-threatening. These tumors often appear as:

  • Open sores
  • Red, scaly patches
  • Warts
  • Raised growths with a dip in the middle

What is melanoma and what does it look like?

Melanoma is the most dangerous form of skin cancer that causes abnormal skin cells to multiply rapidly and create malignant tumors. Although it’s not the most common type of skin cancer, melanoma causes the most deaths. However, it’s curable if it’s detected and treated early on.

This type of skin cancer often looks like a mole. Some melanomas even start out as moles. Most melanoma tumors are black or brown, but they can have other colors, including:

  • Flesh-colored
  • Pink
  • Purple
  • Red
  • Blue
  • White
