What is Squamous Cell Cancer?
Squamous cell cancer, or squamous cell carcinoma (SCC), is a type of skin cancer that originates in the squamous cells.
These cells are found in the outermost layer of the skin, known as the epidermis, as well as in the lining of the body’s organs, respiratory tract, and digestive tract.
This type of cancer occurs when these squamous cells grow uncontrollably, resulting in a variety of skin abnormalities.
Let’s delve into the specifics of squamous cell cancer and its various types:
-
Head and Neck Squamous Cell Carcinoma (HNSCC): As the name suggests, this type of SCC affects the mucosal lining of the head and neck regions, including the mouth, throat, and nasal passages. It’s one of the most common types of cancer in these regions and often associated with tobacco and alcohol use. HNSCC can present several challenges in treatment due to its aggressive nature and location. The National Cancer Institute offers a detailed guide on the signs, symptoms, and treatment options for HNSCC.
-
Squamous Cell Carcinoma of the Anal Canal: This rare form of cancer occurs in the anal canal, the short tube at the end of the rectum through which waste leaves the body. It accounts for the majority of anal cancers and is often associated with human papillomavirus (HPV) infection.
-
Squamous Cell Carcinoma of the Lung: This is a type of non-small cell lung cancer, making up about 30% of all lung cancer cases. It often begins in the bronchi near the middle of the lungs. More information on this type of cancer can be found on the American Cancer Society’s website.
-
Cutaneous Squamous Cell Carcinoma (cSCC): This is the second most common form of skin cancer, occurring in the squamous cells of the skin’s outermost layer. It often presents as a growing bump or a red, scaly patch that can feel rough to the touch. cSCC is commonly associated with prolonged exposure to the sun or other forms of ultraviolet (UV) radiation.
Squamous cell cancer is a diverse disease, affecting various parts of the body and presenting in several forms.
It underscores the importance of regular screenings, particularly for individuals with an elevated risk.
As we explore further into squamous cell cancer’s causes, risk factors, and treatments, we can gain a better understanding of this widespread disease and the strides being made towards more effective therapies.
How Common is Squamous Cell Carcinoma and Who Does it Affect?
Squamous Cell Carcinoma (SCC) is the second most common type of skin cancer. According to the Skin Cancer Foundation, it is estimated that more than one million cases of SCC are diagnosed each year in the United States alone.
This number, while substantial, likely underrepresents the actual incidence rate due to under-reporting.
SCC can affect individuals of all ages, genders, and ethnicities. However, certain groups are at a higher risk. Let’s explore who is most commonly affected by SCC:
-
Older Adults: While SCC can occur at any age, it is most common in adults over the age of 50. This is likely due to cumulative sun exposure and decreased efficiency of the body’s natural repair mechanisms.
-
People with Light Skin: Individuals with lighter skin, blue or green eyes, and blond or red hair have a higher risk of developing SCC. They have less melanin, the pigment that helps protect the skin from the harmful effects of the sun’s ultraviolet (UV) radiation.
-
Individuals with a History of Sun Exposure or Tanning: Prolonged exposure to the sun or usage of tanning beds increases the risk of SCC. Outdoor workers and sunbathers are particularly at risk.
-
Immunocompromised Individuals: People with weakened immune systems due to conditions like HIV/AIDS or those undergoing treatments such as chemotherapy or organ transplantation are at an elevated risk.
-
People with a History of Precancerous Skin Conditions or Skin Cancer: Those who have had skin cancer before or precancerous skin conditions, such as actinic keratosis, are more likely to develop SCC.
While these groups have a higher risk, it is essential to remember that SCC can affect anyone. Therefore, practicing sun safety, regular skin checks, and timely medical consultations are crucial for everyone.
The American Academy of Dermatology provides a comprehensive resource on SCC, including prevention tips and guidance on recognizing potential signs of this condition.
