# Treatment methods for head and neck cancer
Treatment of head and neck cancer depends greatly on the type of tumor, the stage at which it is detected, its location, and your overall health. Usually, different treatments are combined. Below, the standard approaches per treatment group are explained.
---
Surgery
Surgery is often the first step, especially when the tumor is locally confined. The surgeon tries to remove the tumor and surrounding tissue with a sufficient safety margin.
ProveniIncluded in official guidelines, or approved by EMA or FDA
*Primary tumor removal (resection)*
The tumor and some healthy tissue around it are surgically removed. This can be a minor procedure (for example, polypectomy in the mouth or throat) or a larger operation that affects more structures, such as partial removal of the jaw, tongue, or larynx. The extent depends on the size and location of the tumor. Possible side effects are bleeding, infections, swelling, permanent taste changes, speech problems, or swallowing difficulties (especially when much of the tongue or throat is removed).
ProveniIncluded in official guidelines, or approved by EMA or FDA
*Lymph node removal (neck dissection)*
When cancer may have spread to lymph nodes in the neck, these can be removed. This can occur together with the tumor or as a separate procedure. Side effects can include swelling, numbness in parts of the neck and shoulder, and reduced shoulder mobility.
ProveniIncluded in official guidelines, or approved by EMA or FDA
*Reconstruction*
After extensive tissue removal, reconstructive surgical repair may be necessary, sometimes with tissue from elsewhere in the body (for example, skin or muscle from the forearm). This helps restore function and appearance.

Radiation (Radiotherapy)
Radiation destroys cancer cells by causing DNA damage. It is often used as an additional treatment after surgery or as the main treatment.
ProveniIncluded in official guidelines, or approved by EMA or FDA
*External beam radiation therapy (EBRT)*
A device outside the body directs focused radiation energy at the tumor. This usually happens five days a week for several weeks. The dose is adjusted as precisely as possible to the tumor to spare healthy tissue. Many patients experience fatigue, skin redness, dry mouth, taste changes, and sore throat. For long-term effects, dry mouth, jaw stiffness, hair loss in the irradiated area, and in rare cases, damage to the jawbone may occur.
ProveniIncluded in official guidelines, or approved by EMA or FDA
*Intensity-modulated radiation therapy (IMRT)*
This is an advanced form of external radiation where the radiation intensity is adjusted to the shape of the tumor. This can spare more healthy tissue than conventional radiation. Side effects resemble those of standard external radiation, but may be less severe.
ProveniIncluded in official guidelines, or approved by EMA or FDA
*Brachytherapy (internal radiation)*
Radioactive material is placed directly in or near the tumor, sometimes as a supplement to external radiation. This is used less frequently for head and neck cancer. Risks include infection, bleeding, and damage to surrounding tissues.

Chemotherapy
Chemotherapy consists of drugs that attack rapidly dividing cells, including cancer cells, but healthy cells can also be damaged.
ProveniIncluded in official guidelines, or approved by EMA or FDA
*Induction chemotherapy (neoadjuvant chemotherapy)*
Chemotherapy is given before the main treatment (surgery or radiation) to shrink the tumor. This is usually applied in advanced stages. Side effects can include nausea, vomiting, hair loss, reduced blood cell levels (which can cause infections and anemia), and fatigue.
ProveniIncluded in official guidelines, or approved by EMA or FDA
*Concurrent chemoradiation*
Chemotherapy and radiation are given at the same time. This increases the chance of tumor control, but side effects can be more severe: severe mouth and throat inflammation, difficulty swallowing, vomiting, fatigue, and sometimes damage to the esophagus and gastrointestinal tract.
ProveniIncluded in official guidelines, or approved by EMA or FDA
*Adjuvant chemotherapy*
Chemotherapy after the primary treatment (surgery or radiation) to prevent cancer from returning. This is used less frequently than induction and concurrent chemotherapy. The same side effects as induction chemotherapy can occur.
---
Immunotherapy (immunotherapy)
These treatments help the body's immune system recognize and attack cancer cells better.
ProveniIncluded in official guidelines, or approved by EMA or FDA
*PD-1 inhibitors (checkpoint inhibitors)*
Medicines such as pembrolizumab block a brake on the immune system, so that T-cells can attack cancer cells better. This is used for advanced or recurrent cancer, sometimes in combination with chemotherapy or radiation. Side effects can include autoimmune-like reactions (body cells are attacked), such as lung inflammation, bowel inflammation, thyroid inflammation, skin rash and in rare cases heart muscle inflammation.
ResearchediPositive results in clinical studies, not yet standard treatment
*mTOR inhibitors in combination with immunotherapy*
Recent research suggests that inhibition of the mTOR protein (which helps cells grow) can 'reprogram' the immune system to work better against cancer cells, especially in tumors with certain genetic features. This is not yet standard, but is being investigated in studies, sometimes combined with checkpoint inhibitors. Side effects may be similar to immunotherapy alone, but studies are still ongoing.
ResearchediPositive results in clinical studies, not yet standard treatment
*Combinations of immunotherapies*
Combining different immunotherapies (for example PD-1 inhibitor plus CTLA-4 inhibitor) is being tested in studies, especially for advanced disease. Side effects can be serious due to enhanced immune activation.
---
Targeted therapy
These medicines target specific abnormalities in cancer cells.
ProveniIncluded in official guidelines, or approved by EMA or FDA
*EGFR inhibitors*
In some head and neck cancers, the EGFR protein functions abnormally, which fuels tumor growth. Medicines that block EGFR can inhibit growth. This is used especially in combination with radiation for advanced disease. Side effects include skin rash (resembles acne), dry skin, nail problems and diarrhea.
ResearchediPositive results in clinical studies, not yet standard treatment
*Therapies targeting other genetic abnormalities*
Tumors can have mutations in other genes (for example TP53). Treatments targeting these are being tested in studies, especially for rarer subtypes or when other treatments do not help. This is not yet routine.
---
Supportive care (symptom management)
These are not treatments that attack cancer, but help manage side effects and symptoms.
ProveniIncluded in official guidelines, or approved by EMA or FDA
*Care for mouth and throat problems*
Good dental care, rinsing, artificial saliva and sometimes medicines help with dry mouth and mouth and throat inflammation caused by treatment.
ProveniIncluded in official guidelines, or approved by EMA or FDA
*Speech-language pathology (speech therapy)*
Speech-language pathologists help with speech and swallowing problems, both during and after treatment.
ProveniIncluded in official guidelines, or approved by EMA or FDA
*Nutritional support*
Dietitians help when eating and drinking are difficult, sometimes with nutritional drinks or feeding tubes.
ProveniIncluded in official guidelines, or approved by EMA or FDA
*Psychological support*
Counseling and psychological help support anxiety, depression and the burden of cancer treatment.
---
Surveillance and follow-up
ProveniIncluded in official guidelines, or approved by EMA or FDA
*Regular follow-up*
After treatment, patients are regularly checked with physical examination, possibly imaging (CT, MRI) and other tests. This helps detect recurrence (return of cancer) early. The frequency decreases as time passes.
