risk factors
people who smoke and drink alcohol are most likely to contract throat cancer, and are also much more likely to develop the disease than people who just smoke
or drink,
the canadian cancer society says. the disease is also common in people who have been exposed to asbestos or sulphuric acid.
other risk factors for throat cancer include viral infections like
human papillomavirus (hpv) or epstein-barr, as well as gastroesophageal reflux disease (gerd).
there are also some demographic factors: throat cancer is much more common in men than women, usually occurs in people over the age of 65, and is seen more often in black men.
diagnosis
doing a biopsy on a tumour, as in horgan’s case, is the most common way throat cancer is diagnosed,
webmd reports. imaging tests like mris, ct scans, pet scans and x-rays can track the cancer’s size and its spread through the body. doctors may also examine the throat
using a laryngoscopy (an exam using a tube with a light attached), a laryngostroboscopy (where a camera is attached) or a panendoscopy, which involves endoscopies of the throat, esophagus and lungs.
treatment and prognosis
throat cancer, like other cancers, is measured in stages. stages i and ii remain in one part of the throat, stage iii has traveled either to other parts of the throat or to the lymph nodes, and stage iv refers to when it is found in the lymph nodes and head, neck or chest. stage iv affects other organs, like the lungs or liver.
treatment options depend on the cancer’s stage in the body. if throat cancer is detected very early, tumours can be removed surgically, through an endoscopy. in many cases, like horgan’s, the cancer is treated with radiation. chemotherapy and targeted therapy drugs are also used in throat cancer treatment.
about
62 per cent of canadians with throat cancer live at least another five years, according to the canadian cancer society. that prognosis can vary, based on a number of factors, including the stage when the cancer is caught, the patient’s age and general health. people whose cancer that started in the glottis tend to live longer than people whose cancers started elsewhere in the throat, followed by the supraglottis (upper larynx) and then the subglottis (lower larynx).
