You don't always need radiation for squamous cell carcinoma (SCC), but it's used as a primary treatment for large or surgically difficult tumors, for those who can't have surgery, and often after surgery (adjuvant therapy) to kill lingering cells and prevent recurrence, especially if the cancer is aggressive or involves nerves. For advanced SCC, radiation helps shrink tumors before surgery or treat lymph nodes. Your oncology team decides based on tumor size, location, your health, and risk factors.
Radiation therapy can be effective for treating squamous cell carcinoma lesions that develop in the outer layer of the skin (epidermis).
Mohs surgery has the highest cure rate of all therapies for squamous cell carcinomas.
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.
Immunotherapy for Advanced Basal or Squamous Cell Skin Cancers. Immunotherapy is the use of medicines to stimulate a person's own immune system to recognize and destroy cancer cells more effectively.
Mohs Surgery
Mohs micrographic surgery is considered the gold standard for SCC treatment. This is especially the case for lesions on cosmetically sensitive areas like the face, neck, and hands. It involves removing the cancer layer by layer while examining each layer under a microscope.
Squamous cell carcinoma rarely metastasizes (spreads to other areas of the body), and when spreading does occur, it typically happens slowly. Indeed, most squamous cell carcinoma cases are diagnosed before the cancer has progressed beyond the upper layer of skin.
Scarring. You'll have a scar. The size and shape of your scar will depend on how big the skin cancer was and if you needed a skin graft or flap. Scars are quite noticeable and red to start with, but they get paler and less noticeable over time.
If squamous cell carcinoma spreads to the lymph nodes or other parts of the body, chemotherapy can be used alone or with other treatments, such as targeted therapy and radiation therapy. Targeted therapy. Targeted therapy uses medicines that attack specific chemicals in the cancer cells.
Usually the treatments are given in daily sessions, 5 days a week for 5 to 6 weeks.
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. Protecting your skin from UV light can help reduce the risk of squamous cell carcinoma of the skin and other forms of skin cancer.
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.
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.
Squamous cell carcinoma (SCC) is one of the most common types of skin cancer, often caused by prolonged exposure to ultraviolet (UV) radiation. While many cases can be treated effectively, recurrence is a possibility that patients should be aware of.
Doctors can cure most people with squamous cell skin cancer. A small number of people might have squamous cell cancer that has spread to the lymph nodes or to other parts of the body. This may still be cured.
Squamous cell carcinoma is a malignant tumor of epidermal keratinocytes that invades the dermis; this cancer usually occurs in sun-exposed areas. Local destruction may be extensive, and metastases occur in advanced stages.
Squamous Cell Carcinoma (SCC): Radiation therapy is effective for SCC, particularly for tumors that are large, have spread to nearby tissues, or are located in areas that are challenging for surgery.
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.
Summary. Surgical excision remains the gold standard for the management of cutaneous squamous cell cancers (SCC) and national guidelines for operative radial margins predict 95% oncological clearance with a margin of 4 mm for low-risk and 6 mm for high-risk tumours.
Squamous cell carcinoma of the skin: Around 3 – 8 percent of patients who were initially diagnosed with this type of skin cancer experienced a recurrence.
The doctor scrapes a little beyond the edge of the cancer to help remove all the cancer cells. The wound is then covered with ointment and a bandage. A scab will form over the area. The wound may take 3 to 6 weeks to heal.
Cemiplimab-rwlc injection is used to treat certain types of cutaneous squamous cell carcinoma (CSCC; skin cancer) that has spread to nearby tissues or to other parts of the body and cannot be treated well with surgery or radiation therapy.
Many doctors will order a PET or CT scan once a squamous cell carcinoma diagnosis has been reached to ensure the cancer has not spread to other parts of the body and is contained within the layers of the skin. Your doctor may also test your lymph nodes near the tumor site.
Both basal and squamous cell skin cancers are relatively slow-growing, but the most important difference between squamous cell skin cancer versus basal cell skin cancer is that squamous cell skin cancer is more likely to spread to other organs. If it spreads, it can be life-threatening.
Mohs surgery is considered the most effective technique for treating many basal cell carcinomas (BCCs) and squamous cell carcinomas (SCCs), the two most common types of skin cancer. Sometimes called Mohs micrographic surgery, the procedure is done in stages, including lab work, while the patient waits.
