Squamous Cell Carcinoma Treatment: Effective Options and What to Expect
Squamous cell carcinoma (SCC) is a common type of non-melanoma skin cancer that arises from the outer layers of the skin. Treatment choices depend on tumor size, location, depth, and patient factors such as immune status and overall health. Early-stage lesions are often curable with local procedures, while larger or recurrent tumors can require more complex medical or multidisciplinary care. Understanding the available surgical and non-surgical approaches, follow-up needs, and prevention strategies helps patients and clinicians make informed decisions about managing this cancer.

What is squamous cell carcinoma and how is it different from melanoma?
Squamous cell carcinoma is a type of skin cancer that develops from squamous cells in the epidermis. It is categorized as non-melanoma skin cancer, distinct from melanoma which arises from pigment-producing melanocytes. SCC typically appears as a scaly patch, a firm red nodule, or an ulcerated lesion and can occur on sun-exposed areas. Unlike melanoma, SCC tends to have a different pattern of spread and is often related to cumulative sun exposure or immunosuppression. Early detection is important because untreated SCC can grow locally and, in some cases, invade deeper tissues or metastasize.
Which skin cancer treatments are surgical?
Surgery is the mainstay for many SCCs. Standard excision with predetermined margins removes the tumor and some surrounding healthy tissue to lower recurrence risk. Mohs micrographic surgery is a tissue-sparing technique that removes the tumor layer by layer while examining margins microscopically during the procedure; it’s often recommended for tumors in cosmetically or functionally sensitive areas or for recurrent lesions. Curettage and electrodesiccation may be used for small, superficial SCCs. Reconstructive options after excision — such as skin grafts or flaps — are considered when removing larger tumors to restore appearance and function.
What medical (non-surgical) options exist for squamous cell carcinoma?
Non-surgical medical approaches can be appropriate for select superficial or inoperable lesions. Topical therapies such as 5-fluorouracil or imiquimod may be used for limited, superficial disease on the skin. Photodynamic therapy combines a photosensitizing agent with targeted light exposure to destroy cancerous cells and can be an option for certain superficial lesions. For advanced, locally aggressive, or metastatic SCC, systemic medical treatments — including targeted agents and immunotherapies — may be considered as part of a comprehensive oncologic plan overseen by specialists.
When is radiation or systemic medical therapy recommended?
Radiation therapy may be used as primary treatment when surgery would cause unacceptable functional or cosmetic outcomes, or as adjuvant therapy when surgical margins are positive and re-excision is not feasible. It’s also an option for patients who are not surgical candidates. Systemic therapies are generally reserved for advanced, recurrent, or metastatic SCC. Recent advances in immunotherapy — notably anti–PD‑1 agents — have expanded options for patients with advanced disease, and targeted therapies can be considered depending on tumor biology and prior treatments. Decisions about radiation or systemic medical treatment are made by multidisciplinary teams tailored to individual risk and goals.
How do follow-up and prevention reduce future skin cancer risk?
After treatment, regular follow-up with a dermatologist or oncologist is important to detect recurrence and new skin cancers early. Follow-up intervals depend on tumor risk factors but typically include periodic full-skin examinations and patient education on self-checks. Preventive strategies focus on sun protection: broad-spectrum sunscreen, protective clothing, seeking shade, and avoiding tanning beds. For people with a history of SCC, clinicians may also review immunosuppressive medications and discuss lifestyle measures to reduce risk. Early recognition and treatment of precancerous lesions, such as actinic keratoses, can also lower the chance of progression to invasive skin cancer.
Conclusion
Squamous cell carcinoma treatment spans a spectrum from simple office-based procedures to complex multidisciplinary care for advanced disease. Treatment selection is individualized based on tumor characteristics, patient health, and cosmetic or functional considerations. Advances in surgical techniques, radiation, topical and systemic medical therapies have improved outcomes, but ongoing surveillance and prevention remain critical components of care. Consulting qualified medical professionals ensures the most appropriate, evidence-based approach for each person.
