Cancer is the uncontrolled growth of abnormal cells in the body which develop when the body’s normal control mechanism stops working. Cancer survival outcomes greatly depend on the type and stage of the cancer so recognising the warning signs is key to improving outcomes. A symptom associated with a rare type of cancer relates to hearing.
If you experience tinnitus, a condition that is characterised by hearing sounds that come from inside the body rather than from an outside source, it may signal nasopharyngeal cancer.
According to the NHS, nasopharyngeal cancer is a rare type of cancer that affects the part of the throat connecting the back of the nose to the back of the mouth (the pharynx).
In the UK, about 250 people are diagnosed with nasopharyngeal cancer each year.
Nasopharyngeal cancer shouldn’t be confused with other types of cancer that also affect the throat, such as laryngeal cancer and oesophageal cancer, explains the health body.
It’s very unlikely they’ll be caused by nasopharyngeal cancer, but it’s best to get them checked out, it adds.
Who is at risk?
The exact cause of nasopharyngeal cancer is unknown, but a number of factors can increase your risk of developing the condition.
Diet may influence your risk of developing the cancer, for example, which may explain why it is more common in parts of Asia and Northern Africa than it is in Europe.
As Cancer Research UK explained: “Diets very high in salt cured meats and fish or pickled foods are more common in some of these places.
“These foods can be very high in nitrates and nitrites, which react with protein to form nitrosamines. These chemicals can damage DNA.”
Studies in Asia have shown that people who eat Chinese cured and salted fish are at an increased risk of nasopharyngeal cancer.
People from China, or with Chinese ancestry living in the UK, have higher rates of nasopharyngeal cancer than other ethnic groups and this might be due to their diet.
There is also some evidence that eating lots of fruit and vegetables could decrease the risk of nasopharyngeal cancer, according to Cancer Research UK.
Other risk factors:
- Being exposed to the Epstein-Barr virus (EBV), a common virus that causes Glandular fever
- Having a job where you’re regularly exposed to hardwood dust
- Having a first-degree relative, such as a parent, who’s had the condition
“Being exposed to the human papilloma virus (HPV) may also increase your risk of developing certain types of nasopharyngeal cancer,” said the NHS.
About three times as many men as women are affected by nasopharyngeal cancer, and the average age at diagnosis is about 50.
How is nasopharyngeal cancer treated?
According to the NHS, the two main treatments for nasopharyngeal cancer are:
- Radiotherapy – where radiation is used to kill cancer cells
- Chemotherapy – where medication is used to kill cancer cells
In most cases, a combination of radiotherapy and chemotherapy will be used.
