Causes and Risk Factors for Squamous Cell Carcinoma (Squamous Cell Skin Cancer)

Overview

Squamous cell carcinoma (SCC) can be caused by a few different factors. The most common cause is exposure to UV light, such as from the sun or tanning beds. Long-term exposure to chemicals that can cause cancer, like certain chemicals in cigarettes, can also contribute to the development of SCC. Additionally, certain types of human papillomavirus (HPV) may play a role in causing SCC, especially when the cancer develops on the genitals. In some cases, SCC can develop inside of scars or chronic open sores.

Non-modifiable Risk Factors (Risk Factors You Can't Change)

Non-modifiable risk factors are risk factors that cannot be changed. Non-modifiable risk factors for Squamous cell carcinoma (SCC) include:

Age: Being over the age of 50 is a risk factor for SCC. As we get older, our skin becomes less able to repair itself and is more susceptible to damage from the sun's UV radiation.
Genetics: Certain genetic factors can increase the risk of developing SCC. These genetic factors may make an individual more susceptible to the harmful effects of UV radiation or affect their body's ability to repair DNA damage.
Race or ethnicity: Although SCC can affect people of all races and ethnicities, there are some differences in susceptibility. For example, individuals with fair skin have a higher risk of developing SCC compared to those with darker skin tones. Fair-skinned individuals have less melanin, which provides natural protection against UV radiation.

It's important to note that these non-modifiable risk factors do not guarantee the development of SCC, but they can increase an individual's chances. Regular skin checks and early detection are also crucial for successful treatment if SCC does develop.

Modifiable Risk Factors (Factors You May Be Able to Change)

There are several modifiable risk factors for SCC, which means that they are factors that can be changed or modified to reduce the risk of developing this type of cancer. Here are some modifiable risk factors for SCC:

Exposure to UV radiation: This includes both natural sunlight and artificial sources like tanning beds. Prolonged and unprotected exposure to UV radiation increases the risk of developing SCC.

It's important to note that these modifiable risk factors are not guarantees that an individual will develop SCC, but they do increase the likelihood. By making positive changes in lifestyle choices, , individuals can significantly lower their risk of developing squamous cell carcinoma.

Reducing Risks

To prevent or reduce the chances of getting squamous cell carcinoma (SCC), there are several actions that a person can take to modify their risk factors. It's important to note that while these actions can help lower the risk, it may not be possible to completely prevent SCC. Here are some steps individuals can take:

Limit sun exposure: It is recommended to limit sun exposure, especially during peak hours (10 a.m. to 4 p.m.), and to use sunscreen with a high SPF and protective clothing including hats.

It's important to remember that these actions are general recommendations and may not apply to everyone. Each person's situation is unique, so it's crucial to consult with your doctor for personalized advice on how to reduce your specific risk factors for SCC.
