  • Treatment for head and neck cancers

    Last reviewed June 2012

    Contents

    Head and neck cancers are treated differently depending on their location and size. Surgery, radiotherapy, chemotherapy or a combination of these treatments can be used to treat the cancer.

    Before recommending treatment doctors determine how easy it is to access a tumour using surgery, the likely success of an operation, and whether surgery will cause major side effects. They weigh up the benefits and impacts of all the treatments and also consider a person’s general health.

    Surgery

    An advantage of surgery is that after the tissue is removed, it can be examined under a microscope to make sure all the tumour has been taken out and is surrounded by normal tissue (clear margins). The examination of the tissue is done by a pathologist. The tissue can also give information about the stage of the cancer which helps doctors decide on further treatment.

    Surgery is generally the fastest treatment and can be repeated if the cancer comes back. Recovery usually depends on how large the cancer is when diagnosed.

    Radiotherapy and chemotherapy

    Radiotherapy may be given on its own or after surgery, with or without chemotherapy.

    Your medical team will help you decide what treatment to have.

    How different cancers are treated

    Oral cancer
    Cancers of the oral cavity are commonly treated with surgery, then radiotherapy if required. Chemotherapy is sometimes used in combination with these treatments.

    Salivary gland cancer
    Surgery is done in most cases. This is usually followed by radiotherapy. Chemotherapy is not usually given unless the cancer has spread and it may be offered as palliative treatment.

    Pharyngeal cancer
    This is usually treated with surgery or radiotherapy. If radiotherapy does not destroy all the cancer cells or if the cancer comes back, surgery may be performed. If surgery is done first radiotherapy may be used afterwards to destroy any remaining cancer cells. Chemotherapy may also be offered usually with radiotherapy.

    Laryngeal cancer
    Where possible early laryngeal cancer is treated with either laser surgery or radiotherapy. For larger cancers radiotherapy is usually combined with chemotherapy (chemoradiation). For advanced cancer surgery is only used if the cancer comes back.

    Chemotherapy may be given first to ease the pressure on a person’s airway while chemoradiation is being planned. Radiotherapy (with or without chemotherapy) will be given after surgery to reduce the chance of the cancer coming back.

    Nasal or paranasal sinus cancer
    These are commonly treated with surgery followed by radiotherapy and/or chemotherapy.

    Before treatment starts

    Dental check-ups
    Head and neck cancer treatment, particularly radiotherapy, can cause dental problems but these can often be prevented. Before starting cancer treatment you must see a dentist or oral medicine specialist for a thorough oral examination and to get an oral health care plan. The plan outlines whether any dentistry work is needed to reduce the chance of future dental problems. A plan also helps you learn good oral health care before, during and after treatment.

    The dentist will probably recommend that decayed or damaged teeth, and healthy teeth that will be affected by radiotherapy, are taken out. These teeth may be removed during cancer surgery or before radiotherapy.

    Radiotherapy permanently affects tissue healing in the treatment area. In rare cases it can cause scarring of the jaw, leading to the bone being exposed in the mouth (osteoradionecrosis or ORN).

    ORN can cause problems if you later need a tooth extraction or surgery to the mouth or jaw.
