UV damage to your skin caused by the sun or tanning beds.
This is the most common contributing factor. Indoor tanning can increase your risk of developing squamous cell skin cancer by 58%1.
Most squamous cell cancers occur on skin that is regularly exposed to sunlight or other ultraviolet radiation. The earliest form of squamous cell cancer is called Bowen disease (or squamous cell carcinoma in situ). This type does not spread to nearby tissues, because it is still in the outermost layer of the skin.
Metastasis of cutaneous squamous cell carcinoma (cSCC) is rare. However, certain tumor and patient characteristics increase the risk of metastasis. Prior studies have demonstrated metastasis rates of 3-9%, occurring, on average, one to two years after initial diagnosis [6].
Most (95% to 98%) of squamous cell carcinomas can be cured if they are treated early. Once squamous cell carcinoma has spread beyond the skin, though, less than half of people live five years, even with aggressive treatment.
Squamous cell carcinoma of the skin is usually not life-threatening, though it can be aggressive. Untreated, squamous cell carcinoma of the skin can grow large or spread to other parts of your body, causing serious complications.
How does squamous cell skin cancer begin? This cancer usually begins when ultraviolet (UV) light from the sun or tanning beds badly damages the skin. The body tries to repair this damage.
Squamous Cell Carcinoma Early Stages
At first, cancer cells appear as flat patches in the skin, often with a rough, scaly, reddish, or brown surface. These abnormal cells slowly grow in sun-exposed areas.
Squamous cell carcinoma is cancer that occurs in the outermost part of the epidermis (skin surface) or the surface of certain portions of the body (areas of the head and neck or genitalia) known as squamous cells.
Oral and oropharyngeal squamous cell carcinomas (OSCC and OPSCC) represent the majority of head and neck squamous cell carcinomas (HNSCC). Human papillomavirus (HPV) is an important etiologic factor together with Epstein-Barr virus (EBV).
Age. Most basal cell and squamous cell carcinomas typically appear after age 50. However, in recent years, the number of skin cancers in people age 65 and older has increased dramatically. This may be due in part to better screening and patient tracking efforts in skin cancer.
Chemotherapy. Chemotherapy uses powerful drugs to kill cancer cells. If squamous cell carcinoma spreads to the lymph nodes or other parts of the body, chemotherapy can be used alone or in combination with other treatments, such as targeted drug therapy and radiation therapy.
In general, the squamous cell carcinoma survival rate is very high—when detected early, the five-year survival rate is 99 percent. Even if squamous cell carcinoma has spread to nearby lymph nodes, the cancer may be effectively treated through a combination of surgery and radiation treatment.
Squamous cell carcinoma rarely metastasizes (spreads to other areas of the body), and when spreading does occur, it typically happens slowly.
Treatment should happen as soon as possible after diagnosis, since more advanced SCCs of the skin are more difficult to treat and can become dangerous, spreading to local lymph nodes, distant tissues and organs.
Yes, squamous cell carcinoma can make you feel tired. It can make a person feel weak and exhausted. During the treatment procedures of squamous cell carcinoma, the patient tends to feel more tired. These types of fatigue that are related to cancer are known as cancer-related fatigue (CRF).
Systemic chemotherapy is not widely used for treating squamous cell carcinoma. In most cases, the cancer cells are confined to one area of skin and, if detected early, can be effectively addressed with localized treatments, such as surgery.
Squamous cell carcinoma stages
These features include: Greater than 2 mm in thickness. Invasion into the lower dermis or subcutis layers of the skin. Invasion into the tiny nerves in the skin.
It is estimated that about 2,000 people die from basal cell and squamous cell skin cancer each year. Older adults and people with a suppressed immune system have a higher risk of dying from these types of skin cancer. It is estimated that 7,990 people will die from melanoma in the United States in 2023.
About 60 percent of people who have had one skin cancer will be diagnosed with a second one within 10 years, says a 2015 study in JAMA Dermatology. Your odds increase dramatically if you've been diagnosed with a second BCC or SCC (or third, or any other number beyond first).
Death from basal and squamous cell skin cancers is uncommon. It's thought that about 2,000 people in the US die each year from these cancers, and that this rate has been dropping in recent years.
