Surgery is the primary treatment for tongue cancer, and most treatment plans start there. Depending on how advanced the cancer is, you may need only surgery, or you may need radiation, chemotherapy, or both afterward. The specific combination depends on the size of the tumor, how deep it has grown, and whether it has spread to nearby lymph nodes.
Surgery as the First-Line Treatment
For most tongue cancers, the surgeon removes the tumor along with a margin of healthy tissue around it. The scope of that surgery varies widely. A small, early-stage tumor might require removing only a small section of the tongue, a procedure called a partial glossectomy. Larger tumors may require removing half the tongue (hemiglossectomy) or, in rare advanced cases, the entire tongue (total glossectomy).
In many cases, surgeons also perform a neck dissection, removing lymph nodes from the neck to check whether cancer has spread. Even when imaging looks clean, microscopic cancer cells can hide in nearby nodes, so this step helps determine the true stage of the disease and guides decisions about follow-up treatment. If cancerous nodes are found, removing them also prevents further spread.
When Radiation or Chemotherapy Is Added
After surgery, your medical team assigns your case to one of three risk categories: low, intermediate, or high. This classification determines what happens next.
- Low risk: No additional treatment is needed. The surgery was enough.
- Intermediate risk: Postoperative radiation therapy is recommended. Factors that place you here include a tumor that grew deeper than 5 millimeters into the tongue or cancer found in one or more lymph nodes.
- High risk: Both radiation and chemotherapy are given together after surgery. The two main triggers for this are a positive surgical margin (cancer cells found at the edge of the removed tissue, suggesting some were left behind) and extranodal extension (cancer that has broken through the wall of a lymph node into surrounding tissue).
When chemotherapy is combined with radiation, a platinum-based drug is the standard choice. For patients who can’t tolerate that regimen, alternative drug combinations with radiation are available. In situations where surgery isn’t feasible, whether because of the tumor’s location, a patient’s overall health, or other factors, radiation with or without chemotherapy can serve as the primary treatment instead.
Targeted Therapy and Immunotherapy
For cancers that are advanced, have come back after initial treatment, or have spread to distant parts of the body, additional drug options come into play. One approach uses a drug that targets a protein on the surface of cancer cells that fuels their growth. By blocking this protein, the drug can slow or stop the cancer from expanding. This type of targeted therapy can be paired with radiation for some earlier-stage cancers, combined with chemotherapy for more advanced disease, or used on its own.
Immunotherapy is another option for recurrent or metastatic cases, particularly when the cancer has progressed after platinum-based chemotherapy. These drugs work by removing the “brakes” that cancer cells put on your immune system, letting your body recognize and attack the tumor. In clinical trials, patients receiving immunotherapy had a one-year survival rate more than double that of patients on standard chemotherapy (36% versus 17%). The response rate was modest, around 13%, but for those who did respond, the benefits were meaningful.
Reconstructive Surgery After Tumor Removal
When a significant portion of the tongue is removed, reconstructive surgery is often performed in the same operation. Surgeons transplant living tissue from another part of your body to rebuild the tongue and restore as much function as possible.
For smaller reconstructions, tissue from the inner forearm is commonly used. This forearm flap is thin and flexible, making it well suited for the mouth where it needs to move for speech and swallowing. For larger defects that need more bulk, surgeons take skin, fat, and sometimes muscle from the outer thigh. In both cases, the transplanted tissue is reconnected to blood vessels in the neck under a microscope to keep it alive, a technique called microvascular reconstruction.
The goal isn’t to create a perfect replica of the original tongue but to provide enough tissue volume and flexibility for you to eat, drink, and speak. How well function returns depends largely on how much of the tongue was removed and the success of rehabilitation afterward.
Recovery and Rehabilitation Timeline
Rehabilitation begins almost immediately. During the first seven days after surgery, while you’re still in the hospital, a speech-language pathologist typically starts working with you on basic swallowing techniques and range-of-motion exercises for the muscles in your mouth and throat. The guiding principle at this stage is “use it or lose it,” keeping those muscles active prevents long-term stiffness and loss of function.
About 10 to 14 days after surgery, the intermediate phase begins. You’ll attend intensive swallowing therapy one to two times per week for three to four weeks. During these sessions, you’ll learn specific techniques to protect your airway while swallowing, such as tucking your chin, tilting your head back, and using a “slurp and swallow” method that helps move food past the area where your tongue can no longer do the work. For patients who had extensive surgery, adaptive tools like squeeze bottles or syringes can help place food toward the back of the mouth, bypassing the parts of the tongue that are missing.
After that intensive stretch, therapy tapers to once a week for another one to two weeks. Most patients continue to see gradual improvement in speech clarity and swallowing ability for months. The timeline varies significantly based on how much tissue was removed and whether radiation was part of the treatment plan, since radiation can cause additional stiffness and swelling that slows progress.
Managing Side Effects of Radiation
Radiation to the mouth and throat area commonly damages salivary glands, leading to chronic dry mouth. This isn’t just uncomfortable. Saliva protects your teeth and helps you chew, taste, and swallow, so losing it has cascading effects on daily life. Current management strategies include saliva substitutes, frequent sips of water, and medications that stimulate whatever salivary gland function remains.
Other common radiation side effects include mouth sores during treatment, changes in taste that can last months, jaw stiffness, and difficulty swallowing. Most of these improve gradually after radiation ends, though dry mouth can be permanent depending on the dose your salivary glands received. Maintaining good oral hygiene becomes especially important, since the loss of saliva dramatically increases the risk of tooth decay.
Survival Rates by Stage
Tongue cancer caught early has a strong prognosis. According to data from the National Cancer Institute’s SEER program (2016 to 2022), the five-year relative survival rates break down clearly by how far the cancer has spread at diagnosis:
- Localized (confined to the tongue): 88.2%
- Regional (spread to nearby lymph nodes): 69.9%
- Distant (spread to other parts of the body): 38.4%
These numbers reflect averages across all tongue cancer patients and don’t account for individual factors like age, overall health, or specific tumor characteristics. But the pattern is clear: early detection makes a significant difference in outcomes. Most tongue cancers are found at the localized or regional stage, when treatment is most effective.
