Treatments for squamous cell carcinoma within the National Health Service are prioritised based on the size, location, and risk profile of the tumour. Because this form of skin cancer has the potential to grow quickly and spread to local lymph nodes, the primary objective of clinical intervention is the complete removal or destruction of malignant cells. Most patients in the United Kingdom undergo straightforward surgical procedures under local anaesthetic, while more complex or advanced cases may require a multidisciplinary approach involving oncology specialists and plastic surgeons. By following established clinical pathways, the medical team aims to achieve a definitive cure while ensuring the best possible functional and aesthetic outcome for the patient.

Surgical excision as the primary treatment
Surgical excision is the most frequently used treatment for squamous cell carcinoma in the United Kingdom because it offers a highly reliable way to confirm the cancer has been fully removed. During this procedure, a surgeon or a trained dermatologist numbs the area with a local anaesthetic and then cuts out the tumour along with a margin of healthy-looking skin. The National Health Service explains that surgical excision involves removing the cancer and a small area of surrounding healthy skin to ensure all the malignant cells have been taken out. The removed tissue is always sent to a laboratory where a pathologist examines the edges under a microscope to verify that no cancer remains.
The size of the margin taken depends on the risk category of the tumour; typically, a margin of four to six millimetres is standard for most lesions. If the pathologist finds that the margins are clear, the treatment is usually considered complete. If cancer cells are found at the edge of the sample, a second procedure may be necessary to ensure total clearance. Surgical excision is highly successful for early-stage squamous cell carcinoma and allows for a rapid recovery, with most patients returning to their normal activities within a few days. The resulting linear scar usually fades significantly over eighteen months, blending into the natural contours of the skin.
Mohs micrographic surgery for high-risk sites
For tumours located in sensitive areas where preserving as much healthy skin as possible is vital, the NHS may offer Mohs micrographic surgery. This technique is particularly valuable for lesions on the nose, eyelids, ears, or lips, where standard excision might lead to significant scarring or functional issues. Unlike traditional surgery, Mohs involves removing the cancer in thin layers and examining each one immediately under a microscope while the patient waits. This real-time analysis allows the surgeon to map any microscopic extensions of the cancer and remove only the affected tissue.
The primary benefit of this specialised approach is its exceptionally high cure rate, which can reach up to ninety-nine per cent for primary tumours. Because the surgeon can verify that the margins are clear on the day of the procedure, it provides immediate peace of mind and allows for the best possible reconstruction of the wound. Mohs surgery is a time-consuming process that may take several hours, but it is considered the gold standard for managing recurrent cancers or those with poorly defined borders. While it is more resource-intensive than standard excision, its ability to spare healthy tissue makes it an essential tool for complex facial reconstructions.
Curettage and cautery for low-risk lesions
Curettage and cautery are minor surgical techniques sometimes used for very small, superficial, or low-risk squamous cell carcinomas on the trunk or limbs. This procedure involves scraping away the abnormal tissue with a spoon-shaped instrument called a curette and then sealing the area with an electric needle (cautery). The scraping process is effective because cancerous tissue is usually softer and more fragile than the surrounding healthy skin, allowing the clinician to feel the difference between the two as they work.
This method does not require stitches and leaves a small, circular scar that eventually resembles a flat, pale freckle. It is a quick and efficient option for patients who may not be suitable for more extensive surgery or for those with multiple small lesions. However, because it does not provide a formal margin for laboratory analysis, it is strictly reserved for the least aggressive subtypes of the disease. If a clinician suspects that the cancer has invaded deeper into the dermal layers, they will almost always opt for a formal surgical excision instead to ensure that the full depth of the tumour is addressed.
The role of radiotherapy in skin cancer care
Radiotherapy uses high-energy X-rays to target and destroy cancer cells and is a vital alternative for patients who are not suitable for surgery. It is often recommended for individuals with significant underlying health conditions or for those with tumours in locations where an operation would be particularly difficult or disfiguring. NICE clinical guidelines state that radiotherapy should be considered as a primary treatment for squamous cell carcinoma if surgery is likely to result in poor cosmetic or functional outcomes. It is also frequently used as an adjuvant treatment after surgery to destroy any remaining microscopic cells and reduce the risk of the cancer returning.
A course of radiotherapy usually involves several short sessions delivered over a period of two to four weeks. While the treatment is painless, the skin in the target area will typically become red, sore, and scaly as the radiation takes effect. These reactions are temporary and usually heal well within a month of completing the course. Radiotherapy is highly effective at managing local disease and is also used to treat cancer that has spread to the regional lymph nodes. By using targeted beams, oncology teams can provide a definitive cure for many patients who might otherwise face a more complex surgical pathway.
Systemic therapies for advanced disease
In cases where squamous cell carcinoma has spread to distant parts of the body or is too advanced to be treated with surgery or radiation alone, the NHS provides access to modern systemic therapies. Immunotherapy drugs, such as cemiplimab or pembrolizumab, have significantly changed the outlook for patients with advanced disease. these medications work by helping the body’s own immune system to recognise and attack the cancer cells. Unlike traditional chemotherapy, immunotherapy targets the biological mechanisms that allow the cancer to hide from the immune response.
These treatments are usually administered through an intravenous drip in a hospital setting every few weeks. While they can be very effective at shrinking tumours and controlling the spread of the disease, they can also cause side effects as the immune system becomes more active. Patients are monitored closely by an oncology team to manage any inflammatory reactions. For a small number of patients, traditional chemotherapy or targeted therapies may also be used, particularly if the cancer has specific genetic markers. These advanced options ensure that even those with complex or metastatic squamous cell carcinoma have access to the latest clinical developments.
Comparison of surgical techniques
When deciding on a surgical approach, the medical team considers the balance between the likelihood of a permanent cure and the impact on the patient’s appearance and function. Standard surgical excision is the most common choice for the majority of the body, providing a clear histological report and a high success rate. Mohs surgery is reserved for high-stakes areas like the face, offering the highest level of precision and tissue sparing. Curettage and cautery serves as a rapid, stitch-free option for the most superficial and low-risk growths on less visible areas.
The choice of treatment is often discussed within a multidisciplinary team meeting, where surgeons, dermatologists, and oncologists review the patient’s specific case. This collaborative approach ensures that the chosen method is tailored to the individual’s health status and the biological behaviour of the tumour. By matching the treatment to the risk, the NHS can provide efficient and successful care that prioritises both clinical safety and the patient’s quality of life.
Conclusion
The main treatments for squamous cell carcinoma in the NHS include surgical excision, Mohs surgery, radiotherapy, and modern systemic therapies. Surgical removal remains the mainstay of care, offering high cure rates and clear histological confirmation. For advanced or difficult-to-treat cases, a combination of radiotherapy and immunotherapy provides a robust alternative to ensure the cancer is managed effectively. If you experience severe, sudden, or worsening symptoms, call 999 immediately.
