Cutaneous squamous cell carcinoma is the second most common cancer in the U.S., but three out of four Americans don't know what it is

Cutaneous squamous cell carcinoma – a type of skin cancer that is the second most common type of cancer in the U.S. – is unknown to 74 percent of Americans, according to a new survey conducted by The Harris Poll on behalf of The Skin Cancer Foundation and in coordination with Regeneron and Sanofi.

CSCC is more common than breast, lung and prostate cancer combined and is estimated to cause more deaths than melanoma.

Yet despite these statistics, the survey found a surprising lack of awareness and understanding.

“During the summer months, skin cancer conversations are largely focused on prevention. Prevention is critical. At the same time, 1 million cases of cutaneous squamous cell carcinoma are expected to be diagnosed in 2019 alone. So discussions on skin cancer identification and treatment are equally as important,” said Skin Cancer Foundation president Dr. Deborah S. Sarnoff. “Although CSCC is far more common than melanoma, these survey findings reveal that CSCC is virtually unknown to most Americans, and most have significant misconceptions of how dangerous it can be if it progresses.”

“Advanced” is a broad term for CSCC that may have spread extensively or have resisted multiple treatments and recurred. An estimated 40,000 people in the U.S. each year learn they have CSCC that has advanced to the point that it may be very challenging to treat.

The findings of the survey, which was fielded by The Harris Poll in May 2019 and surveyed more than 2,000 adults across the country, are:

 -  42 percent of Americans have never heard of CSCC. In contrast, only 11 percent of Americans say they have never heard of melanoma.

  - Only 3 percent of people correctly identified CSCC as one of the three most common types of cancer in the U.S.

  - More than half (54 percent) falsely believe melanoma is the most common type of skin cancer in the US. CSCC is five times more prevalent than melanoma. Basal cell carcinoma is the most common type of skin cancer).

  - 72 percent of Americans don’t understand that non-melanoma skin cancers such as CSCC can spread and become life-threatening.

  - A majority of Americans (58 percent) know advanced melanoma can be life-threatening.

Many people at higher risk for developing CSCC are not familiar with it:

  - 40 percent of people living in the southern U.S. have never heard of CSCC, but they are more likely to develop it than those living in northern states.

  - Only 26 percent of men are familiar with CSCC, though they are three times as likely as women to develop it.

  - CSCC is more common in people 65 years and older. Yet only 35 percent of people in this age group are familiar with it, although they are more familiar than younger people.

About the Survey

The CSCC Skin Cancer survey was conducted online by The Harris Poll on behalf of The Skin Cancer Foundation and in coordination with Regeneron and Sanofi between May 2 to 22, 2019 among 2,010 adults ages 18 and older in the US. Raw data were weighted where necessary by age within gender, race/ethnicity, region, education, income, size of household, marital status, employment status, internet usage and propensity to be online to bring them in line with their actual proportions in the population.
