Nasopharyngeal Cancer Symptoms Children

Nasopharyngeal cancer symptoms children causes. Nasopharyngeal cancer is one of the few head and neck cancers that can be found in children, but the usual age range at the time of diagnosis is 30 to 55. EBV (Epstein-Barr virus) NPC is the most common epithelial cancer in children and adults.

Nasopharyngeal cancer is found twice as often in men and is more common in African-Americans. EBV is transmitted by close person-to-person contact. Primary, or initial, infection with EBV may not produce symptoms or there can be a number of different symptoms, especially in young children.

According to Dr. Lydiatt, you should know about the following symptoms that could be caused by nasopharyngeal cancer:

• Lump in the neck. A painless, enlarged lymph node on one side of the neck is the most common symptoms of nasopharyngeal cancer.
• Trouble hearing. The tube that drains the space behind your eardrum goes into the nasopharynx. Cancer can block the tube, causing fluid to build up. Your ear may feel blocked, and your doctor may be able to see fluid behind the eardrum.
• Nasal problems. Nasopharyngeal cancer can block the back of your nose, making it hard to breathe. You may also get nosebleeds.

"These nose and ear symptoms are much more suspicious if they occur only on one side and are not explained by a cold or an allergy," says Lydiatt. Source: www.everydayhealth.com/oral-head-and-neck-cancer/nasopharyngeal-cancer.aspx

Nasopharyngeal cancer most commonly starts in the squamous cells that line the oropharynx. The detection of nuclear antigen associated with Epstein-Barr virus (EBNA) and viral DNA in NPC type 2 and 3, has revealed that EBV can infect epithelial cells and is associated with their transformation. Nasopharyngeal cancer is a disease in which malignant (cancer) cells form in the tissues of the nasopharynx. More importantly, EBV DNA levels appear to correlate with treatment response and they may predict disease recurrence, suggesting that they may be an independent indicator of prognosis. In adults, other likely etiological factors include genetic susceptibility, consumption of food (in particular salted fish) containing carcinogenic volatile nitrosamines, and as in children.
