Radiation therapy is a wonderful tool used to treat and often cure many cancers when the cancer is localized to one place in the body. In select cases, radiation therapy can be used a second time in the same patient. If cancer is being treated in a different area of the body, this is an easy question.
How do you know if radiotherapy is working?
There are a number of ways your care team can determine if radiation is working for you. These can include: Imaging Tests: Many patients will have radiology studies (CT scans, MRI scans, PET scans) during or after treatment to see if/how the tumor has responded (gotten smaller, stayed the same, or grown).

Why is it important to know the stage of a laryngeal cancer?
It is important to know the stage of the disease in order to plan treatment. The results of some of the tests used to diagnose laryngeal cancer are often also used to stage the disease.
Where is the vocal cord located?
Glottis: The middle part of the larynx where the vocal cords are located. Subglottis: The lower part of the larynx between the vocal cords and the trachea (windpipe). Laryngeal cancer forms in the tissues of the larynx (area of the throat that contains the vocal cords).
Where is the larynx?
The larynx is a part of the throat, between the base of the tongue and the trachea. The larynx contains the vocal cords, which vibrate and make sound when air is directed against them.
Where does cancer spread?
Cancer has spread through the thyroid cartilage and/or has spread to tissues beyond the larynx, such as the neck, trachea, thyroid, or esophagus. Cancer may have also spread to one lymph node on the same side of the neck as the primary tumor and the lymph node is 3 centimeters or smaller; or.

External beam radiation therapy
During external beam radiation therapy, a machine directs radiation through the skin to the tumour and some of the tissue around it.
3-D conformal radiation therapy (3-D CRT)
3-D conformal radiation therapy (3-D CRT) delivers radiation beams of equal strength to the tumour from several different directions. This can decrease the radiation damage to normal tissues and increase the radiation to the tumour.
Intensity-modulated radiation therapy (IMRT)
Intensity-modulated radiation therapy (IMRT) delivers radiation beams of different strengths directed at the tumour from several different directions. This method shapes the treatment beams very precisely and allows the dose of radiation to be adjusted for different parts of the treatment area.

Ultimate Survival and Tumor Control Are First Priority. While the patient and physician must consider all options, control of the tumor, and ultimately survival, are the main considerations in deciding on a treatment for advanced laryngeal cancer.
How to restore voice after laryngectomy?
There are three main ways to restore voice after total laryngectomy. The first way to restore speech after laryngectomy is the use of pharyngo-esophageal speech, which can be learned with the assistance of an SLP.
What is the emphasis on the larynx?
Both patients and physicians are currently placing a renewed emphasis on treatment approaches that preserve key functions of the larynx – breathing, protecting the airway during swallowing, and producing voice. This emphasis is influencing both surgical and non-surgical treatment approaches. Red Flag.
Can laryngeal surgery cause loss of voice?
Loss of laryngeal function occurs obviously in surgical procedures that remove part of the larynx (partial laryngectomies). Although these procedures may seem wholly destructive to the larynx, preservation of laryngeal function can be addressed, resulting in restoration and/or rehabilitation of voice.
What to do after laryngectomy?
If you need more treatment after surgery, your options might include radiation therapy, chemoradiation, or surgery to remove more of the larynx. Supraglottic cancer: Supraglottic cancers are more likely to spread to the lymph nodes in the neck. If you're having surgery for supraglottic laryngectomy, the surgeon might also remove lymph nodes ...
What is the treatment for stage 1 hypopharyngeal cancer?
Stage I hypopharyngeal cancers. The main options for initial treatment of these cancers are surgery with or without radiation to the lymph nodes. Surgery includes removing all or part of the pharynx (throat) as well as lymph nodes on one or both sides of the neck (lymph node dissection).
What is the first treatment for cancer?
Another option is to first treat with both radiation and chemo ( chemoradiation ). If any cancer remains after treatment, surgery can try to remove it. A third option is to get chemotherapy as the first treatment, called induction chemotherapy.
What is the best treatment for thyroid cancer?
In these cases, the best treatment may be surgery to remove the larynx and nearby tissues with cancer (such as the thyroid gland). Another option may be to start with just chemotherapy, which is called induction chemotherapy. If the tumor shrinks, radiation therapy or chemoradiation is then given.
How to treat glottic cancer?
Glottic cancer: Some early glottic cancers might be treated by removing the vocal cord with cancer ( cordectomy ), or even by laser surgery. Radiation or surgery is usually enough to treat most glottic cancers unless there are signs that the treatment might not have cured the cancer (such as finding cancer cells at the edge of the removed tumor).
What to do if lymph nodes are enlarged?
If the tumor does not shrink, surgery might be done. If the lymph nodes in the neck are still enlarged after treatment, surgery can be done to remove them (lymph node dissection).
