Skin Cancer

Squamous cell skin cancer

Squamous-cell skin cancer, also known as cutaneous squamous-cell carcinoma (cSCC), is one of the main types of skin cancer along with basal cell cancer, and melanoma.[10] It usually presents as a hard lump with a scaly top but can also form an ulcer.[1] Onset is often over months.[4] Squamous-cell skin cancer is more likely to spread to distant areas than basal cell cancer.[11]

The greatest risk factor is high total exposure to ultraviolet radiation from the Sun.[2] Other risks include prior scars, chronic wounds, actinic keratosislighter skinBowen’s diseasearsenic exposure, radiation therapypoor immune system function, previous basal cell carcinoma, and HPV infection.[2][12] Risk from UV radiation is related to total exposure, rather than early exposure.[13] Tanning beds are becoming another common source of ultraviolet radiation.[13] It begins from squamous cells found within the skin.[14] Diagnosis is often based on skin examination and confirmed by tissue biopsy.[2][3]

Decreasing exposure to ultraviolet radiation and the use of sunscreen appear to be effective methods of preventing squamous-cell skin cancer.[5][6] Treatment is typically by surgical removal.[2] This can be by simple excision if the cancer is small otherwise Mohs surgery is generally recommended.[2] Other options may include application of cold and radiation therapy.[7] In the cases in which distant spread has occurred chemotherapy or biologic therapy may be used.[7]

As of 2015, about 2.2 million people have cSCC at any given time.[8] It makes up about 20% of all skin cancer cases.[15] About 12% of males and 7% of females in the United States developed cSCC at some point in time.[2] While prognosis is usually good, if distant spread occurs five-year survival is ~34%.[4][5] In 2015 it resulted in about 51,900 deaths globally.[9] The usual age at diagnosis is around 66.[4] Following the successful treatment of one case of cSCC people are at high risk of developing further cases.[2]

Kansas City

Kansas City is the largest city in Missouri and the sixth largest city in the Midwest. According to the U.S. Census Bureau, the city had an estimated population of 475,378 in 2015,[6] making it the 36th largest city by population in the United States. It is the anchor city of the Kansas City metropolitan area, which straddles the KansasMissouri border. Kansas City was founded in the 1830s as a Missouri River port at its confluence with the Kansas River coming in from the west. On June 1, 1850 the town of Kansas was incorporated; shortly after came the establishment of the Kansas Territory. Confusion between the two ensued and the name Kansas City was assigned to distinguish them soon thereafter.

Sitting on Missouri’s western border, with Downtown near the confluence of the Kansas and Missouri rivers, the modern city encompasses some 319.03 square miles (826.3 km2), making it the 23rd largest city by total area in the United States. Most of the city lies within Jackson County, but portions spill into ClayCass, and Platte counties. Along with Independence, it serves as one of the two county seats for Jackson County. Major suburbs include the Missouri cities of Independence and Lee’s Summit and the Kansas cities of Overland ParkOlathe, and Kansas City.

 

The city is composed of several neighborhoods, including the River Market District in the north, the 18th and Vine District in the east, and the Country Club Plaza in the south. Kansas City is also known for its cuisine (including its distinctive style of barbecue), its craft breweries and its major league sports teams.
