Yes, squamous cell carcinoma (SCC) has a genetic component, meaning some people have a higher inherited risk, though it's primarily triggered by environmental factors like UV exposure, leading to DNA mutations (like in the p53 gene) that cause uncontrolled cell growth, with genetic predispositions making certain individuals more vulnerable. While sun exposure is a major cause, genetic factors, family history, and inherited syndromes increase susceptibility, influencing how well your cells repair DNA damage.
Metastatic squamous neck cancer with occult primary is a disease in which squamous cell cancer spreads to lymph nodes in the neck and it is not known where the cancer first formed in the body. Signs and symptoms of metastatic squamous neck cancer with occult primary include a lump or pain in the neck or throat.
Most squamous cell carcinomas of the skin are caused by too much ultraviolet (UV) radiation. UV radiation comes either from sunlight or from tanning beds or lamps.
Surgery is the main treatment for SCC of the eye in the conjunctiva. Whether you are offered surgery and what surgery you have depends on the size of the tumour and how much surrounding tissue is affected. The area of normal tissue surrounding a tumour that is removed along with the tumour during surgery.
Oropharyngeal squamous cell carcinoma, commonly known as throat cancer or tonsil cancer, is a type of head and neck cancer that refers to the cancer of the base and posterior one-third of the tongue, the tonsils, soft palate, and posterior and lateral pharyngeal walls.
Heredity can raise risk, especially with inherited syndromes like Gorlin syndrome (PTCH1) or Fanconi anemia (DNA repair genes). Inherited mutations in TP53 or CDKN2A may increase susceptibility, but most SCC is not directly inherited.
Squamous cell carcinoma comprises over 95% of oropharyngeal cancers. Tobacco and alcohol are major risk factors, but human papillomavirus (HPV) causes most of these tumors. Symptoms include sore throat and painful and/or difficult swallowing.
It's important not to delay treatment for too long, since this can make the cancer more difficult to cure. Waiting to treat squamous cell skin cancer also increases the risk of hurting your appearance and leading to difficulties with using that part of the body normally if a lot of surgery or other treatment is needed.
The skin around them typically shows signs of sun damage such as wrinkling, pigment changes and loss of elasticity. SCCs can appear as thick, rough, scaly patches that may crust or bleed. They can also resemble warts, or open sores that don't completely heal.
While you can't prevent all types of squamous cell carcinoma, you can take steps to reduce your risk by: Avoiding excessive sun exposure. Avoid using tanning beds. Using sunscreen when you're outdoors.
There is also a genetic basis for SCC, as evidenced by an increased risk among first-degree relatives of SCC cases,3–7 and from hereditary syndromes that are associated with an increased risk of SCCs. The contribution of family history of skin cancer to overall SCC risk has not been systematically examined.
Taken together, these results suggest that regulatory/suppressor T cells play an important role in chronic stress-induced immunosuppression, and increased susceptibility to squamous cell carcinoma.
Over the past 20 years, high-risk human papillomavirus (HPV) infection has been established as a risk factor for developing head and neck squamous cell carcinoma, independent of tobacco and alcohol use.
Treatment overview
In July 2021, the FDA expanded this approval to include SCC that is locally advanced and not curable by radiation or surgery. In 2024, the FDA approved cosibelimab-ipdl (UnloxcytTM) for adults with locally advanced or metastatic squamous cell carcinoma that is not curable with surgery or radiation.
Squamous cell carcinoma is the second most common type of skin cancer in the United States, after basal cell carcinoma. It also makes up about 90 percent of all head and neck cancers. Early detection and treatment are essential for the best outcomes.
Inheritance. HNSCC is generally not inherited; it typically arises from mutations in the body's cells that occur during an individual's lifetime. This type of alteration is called a somatic mutation. Rarely, HNSCC is found in several members of a family.
The majority of squamous cell carcinomas are caused by sun exposure.

Signs and symptoms of squamous cell skin cancer
They can also develop in scars or skin sores elsewhere. These cancers can appear as: Rough or scaly red (or darker) patches, which might crust or bleed. Raised growths or lumps, sometimes with a lower area in the center.
Surgery to remove the cancer (surgical excision) is the most common treatment for invasive basal cell carcinoma BCC and squamous cell carcinoma SCC. Most small skin cancers are removed by a GP or a dermatologist in their consulting rooms. A surgeon may treat more complex cases.
You might have different types of doctors on your treatment team. Most basal and squamous cell cancers (as well as pre-cancers) are treated by dermatologists – doctors who specialize in treating skin diseases.
FDG-PET/CT can identify primary and locoregional disease in cSCC patients with high sensitivity, including small cutaneous and clinically impalpable nodal lesions, and thus has a potential role in initial staging and modifying subsequent treatment strategy.
OSCC can affect any site of the oral mucosa and large lesions can invade several continuous areas. The present results showed that the border of tongue, gingiva/alveolar mucosa and floor of mouth/ventral tongue were the most commonly affected locations.
Alcohol intake is associated with increased risk of squamous cell carcinoma of the skin: three US prospective cohort studies.
Mouth (oral cavity) cancers
around 60 out of every 100 (around 60%) will survive their cancer for 5 years or more after diagnosis.
