Yes, Stage 3 squamous cell carcinoma (SCC) is often curable, but it's more challenging than earlier stages because the cancer has spread to lymph nodes or deeper tissues, requiring aggressive combination treatments like surgery, radiation, and chemotherapy/immunotherapy, with survival rates decreasing but still showing significant long-term potential with effective care. The goal shifts from simple removal to controlling the spread, with a 5-year survival rate around 66% if it reaches nearby lymph nodes, but this varies greatly by location and treatment response, emphasizing the need for diligent follow-up.
Early stages (0, 1, and 2) of SCC often can be cured with surgery or other treatments. In stages 3 and 4, the cancer has spread to lymph nodes, bones, or organs and requires more complex, combination treatments.
There are effective treatments for many stage 3 cancers. Some stage 3 cancers can be successfully treated, but they are more likely to return after going away. This article reviews how stage 3 cancer is diagnosed. It also explains what this means for a person's treatment and prognosis.
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.
Mohs surgery is highly effective for treating squamous cell carcinoma (SCC) on the nose. Because SCC can be aggressive, it's crucial to remove every cancerous cell without damaging surrounding healthy tissue.
Squamous cell carcinoma of the skin is usually not life-threatening. But if it's not treated, squamous cell carcinoma of the skin can grow large or spread to other parts of the body. The growth of the cancer can cause serious complications.
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.
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.
Non-surgical Local Treatments for Basal and Squamous Cell Skin Cancers. Cryotherapy, photodynamic therapy, topical chemotherapy, or other local treatments might be options to treat basal and squamous cell skin cancers (or pre-cancers) that haven't spread beyond the skin.
So, the patient does not have to lose their voice. Radiation therapy has a 90-95% success rate in stage I, 85-90 % success rate in stage II, and 75-80% success rate in stage III. After radiation therapy, the patient is advised to visit the doctor for follow-up every three months.
Here are some general five-year survival rates for different types of stage 3 cancer: Breast Cancer: Approximately 72% of patients survive five years or longer. Lung Cancer: The five-year survival rate ranges from 36% to 46%, depending on how far the cancer has spread.
Chemotherapy is commonly used to treat stage 3 colon cancer. After surgery, it's often used to kill any remaining cancer cells and reduce the risk of recurrence.
The most recent reports show the five-year survival rate for 11 of those types of cancer ranges between 100% for prostate cancer to 90.9% for colon cancer. Here's information on survival rates for other localized cancers: Thyroid cancer, 99.9%. Melanoma of skin, 99.6%.
In general, the squamous cell carcinoma survival rate is very high—when detected early, the five-year survival rate is 99 percent. Even if squamous cell carcinoma has spread to nearby lymph nodes, the cancer may be effectively treated through a combination of surgery and radiation treatment.
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.
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.
Most recurrent lesions develop within two years after the completion of treatment to remove or destroy the initial cancer. However, there is no time limit for a recurrence.
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.

They stretch down from the oral cavity into the esophagus and lungs; they can be found in the cervix, anus and bladder, too. Eventually, the surface lining changes, though, and that's where you start getting into adenocarcinomas. Are there any features common to all squamous cell carcinomas?
In stage IIIA, cancer has spread (1) into the mucosa layer, thin muscle layer, or submucosa layer of the esophagus wall. Cancer is found in 3 to 6 lymph nodes near the tumor; or (2) into the thick muscle layer of the esophagus wall. Cancer is found in 1 or 2 lymph nodes near the tumor.
Metastatic squamous cell carcinoma is often referred to as a neck cancer because it tends to travel to the lymph nodes in the neck and around the collarbone. Because of this, signs of metastasis may include a painful or tender lump in the neck or a sore throat that doesn't improve or go away.
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.
If the doctor thinks that a suspicious area might be skin cancer, the area (or part of it) will be removed and sent to a lab to be looked at under a microscope. This is called a skin biopsy. If the biopsy removes the entire tumor, it's often enough to cure basal and squamous cell skin cancers without further treatment.
While surgery is the most common treatment approach for basal and squamous cell skin cancers, radiation therapy may be used as the main treatment in some situations. For example, radiation might be used if a skin tumor is very large or if it's in an area that makes it hard to remove with surgery.
