Tongue Cancer: Diagnosis, Surgery, and Recovery

Tongue cancer is one of the most common cancers of the oral cavity, and it is also one of the most significant. Because the tongue plays a central role in eating, swallowing, and speaking, cancer in this location carries implications that extend well beyond removing the tumor itself. What happens afterward — how you eat, how you talk, how your mouth works — matters enormously, and planning for that recovery begins at the time of diagnosis.

I want to walk you through what tongue cancer actually is, how it is diagnosed and staged, what surgery involves, and what recovery looks like over the weeks and months that follow.

What Is Tongue Cancer?

The tongue has two anatomically distinct parts: the oral tongue (the front two-thirds that you can stick out) and the base of the tongue (the back third, which sits in the throat and is technically part of the oropharynx). When most people say “tongue cancer,” they are referring to cancer of the oral tongue — and that is the focus of this article.

The vast majority of oral tongue cancers are squamous cell carcinomas, meaning they arise from the flat cells lining the surface of the tongue. They most commonly appear on the lateral border — the sides of the tongue — rather than the top or tip.

The primary risk factors for oral tongue cancer are tobacco use and heavy alcohol consumption, particularly in combination. However, tongue cancer also occurs in patients who have never smoked or drank — it is not rare to diagnose this cancer in younger, otherwise healthy individuals, often without a clear identifiable cause.

Recognizing the Warning Signs

Most oral tongue cancers begin as a persistent ulcer or sore on the side of the tongue that does not heal. The sore may be painful or, in many cases, entirely painless — which is one reason patients sometimes delay seeking attention. Other warning signs include a white or red patch on the tongue that does not resolve, persistent numbness or altered sensation in the tongue, and, in more advanced cases, difficulty moving the tongue or pain that radiates to the ear.

Any lesion on the tongue that has been present for more than two to three weeks without a clear explanation — a bite injury, for example — warrants evaluation by a specialist. The fact that something does not hurt does not mean it is benign.

Diagnosis and Staging

Diagnosing tongue cancer requires a biopsy — a tissue sample that is examined under the microscope by a pathologist. In many cases, this can be done in the office or under a brief anesthetic. Imaging typically follows: a CT scan of the neck to evaluate for lymph node involvement, and sometimes an MRI to better assess the depth of invasion into the tongue muscle itself.

Depth of invasion is particularly important in tongue cancer. Tumors that invade more deeply into the tongue muscle — even when they are small on the surface — carry a significantly higher risk of spreading to the lymph nodes of the neck. Thin tumors of 2–3 millimeters depth behave quite differently from tumors invading 8–10 millimeters, even if both appear similarly sized on exam.

Staging follows the standard TNM system — the size and depth of the primary tumor, whether lymph nodes are involved, and whether there is distant spread. This staging drives decisions about the extent of surgery and whether additional treatment, such as radiation therapy, will be needed.

Surgery: What Happens in the Operating Room

The surgical resection of an oral tongue cancer is called a glossectomy — partial, hemi, or total, depending on the extent of disease. For most localized tongue cancers, I perform a partial glossectomy, removing the tumor with a clear margin of normal tissue on all sides. The goal is always to achieve what pathologists call a “clear margin” — no cancer cells at the cut edges — while preserving as much functional tongue tissue as possible.

Simultaneously, I evaluate and address the lymph nodes of the neck. Because tongue cancer has a meaningful rate of occult (clinically undetectable) lymph node spread, I routinely perform a neck dissection at the time of the primary surgery, even when the neck appears clear on imaging. For certain smaller, superficial tumors, a sentinel lymph node biopsy may be appropriate to sample the first draining lymph nodes without removing the full nodal chain.

When the tumor is large enough that removing it would leave insufficient tongue tissue to support speech and swallowing, reconstruction becomes part of the operation. The radial forearm free flap — a thin, pliable tissue flap harvested from the forearm — is one of the most commonly used reconstructive options for tongue defects. It restores bulk and surface coverage without the stiffness of a muscle-based flap, which matters when the remaining tongue needs to move freely for speech and swallowing. I take great care in planning the reconstruction so that function is preserved as much as anatomy allows.

What to Expect in the Hospital

Recovery in the hospital following a partial glossectomy typically spans one to two days for straightforward cases, longer if the neck dissection or reconstruction adds complexity. Some patients have a temporary nasogastric feeding tube placed during surgery to allow nutrition while the tongue and oral cavity begin to heal. Oral intake — beginning with liquids and soft foods — is reintroduced as swelling subsides and as the speech and swallowing therapists assess function.

Swelling of the tongue after surgery is significant and can be disorienting — the tongue will feel large and unfamiliar in the first week. This is normal and improves steadily over several weeks as the surgical site heals. Patients with significant reconstruction may notice that the tongue feels different, particularly in terms of sensation, as the reconstructed tissue does not have the same nerve supply as native tongue.

Drains placed in the neck during the neck dissection are typically removed before discharge. Pain is usually well managed with standard medications, and most patients are surprised to find it less severe than they anticipated.

Recovery at Home and the Path Forward

The recovery from tongue surgery is measured in weeks to months, not days. In the first two to four weeks, the primary focus is nutrition, wound healing, and beginning speech and swallowing therapy. We recommend working with a speech-language pathologist experienced in head and neck cancer recovery. The tongue is an extraordinarily adaptable organ, and with skilled therapy, most patients regain functional speech and swallowing even after substantial resections.

If pathology returns with high-risk features — involved or close margins, multiple positive lymph nodes, perineural invasion, or lymphovascular invasion — adjuvant radiation therapy will typically be recommended. In cases with extranodal extension of lymph node disease, concurrent chemotherapy is usually added. I discuss these possibilities honestly before surgery so that patients understand the full picture of what treatment may involve.

The donor site on the forearm, when a radial forearm free flap is used, heals over six to eight weeks. Most patients have a skin graft over the donor site. Sensation returns gradually and incompletely in some patients, and there can be some weakness of grip that generally resolves with hand therapy.

Return to normal activity, including work, depends heavily on the nature of the job and the extent of surgery. Many patients are back to light activity within a month; more physically demanding work may require six to eight weeks or more.

A Note on Follow-Up

Tongue cancer requires close surveillance after treatment. I follow patients every two to three months in the first year, every three to four months in the second year, and at gradually increasing intervals thereafter. Physical exam of the oral cavity and neck is the cornerstone of surveillance; imaging with CT or PET scanning is guided by clinical findings and individual risk. Patients who used tobacco or alcohol are also counseled on cessation and monitored for second primary cancers in the head and neck region.

Early detection of any recurrence gives us the best chance at salvage.

If you have been diagnosed with tongue cancer, or if you have a persistent lesion in your mouth that has not been evaluated, I encourage you to call my office at 414-649-3920 to schedule a consultation. We will review your imaging, perform a thorough examination, and discuss the full range of options available to you — including a second opinion if that is what you need.
