What Is Nasopharyngeal Cancer | Nasopharyngeal carcinoma
What Is Nasopharyngeal Cancer | Nasopharyngeal carcinoma – Nasopharyngeal cancer is a type of head and neck cancer. It begins in the nasopharynx, the upper part of the throat behind the nose and near the base of the skull. Cancer begins when cells begin to grow out of control. Cells can become cancerous in almost any part of the body, and can spread to other areas. – What Is Nasopharyngeal Cancer | Nasopharyngeal carcinoma
Where nasopharyngeal cancer is formed – What Is Nasopharyngeal Cancer | Nasopharyngeal carcinoma
The nasopharynx is the upper part of the throat (pharynx) that is located behind the nose. It is a box-like chamber about 1½ inches at each end. It is situated just above the soft part (soft palate) of the roof of the mouth and just behind the nasal passage.
The nasopharynx serves as a route for air travel from the nose to the throat (and then to the lungs). – What Is Nasopharyngeal Cancer | Nasopharyngeal carcinoma
Types of nasopharyngeal tumors – What Is Nasopharyngeal Cancer | Nasopharyngeal carcinoma
Many types of tumors can develop in the nasopharynx. Some of these tumors are benign (not cancerous), but others are malignant (cancerous). It is important to talk to your doctor about what type of tumor you may have.
Nasopharyngeal Carcinoma (NPC) –
Most are nasopharyngeal nasopharyngeal carcinoma (NPC). It is by far the most common cancer in the nasopharynx. Carcinoma is cancer that starts in cells that are called internal and external surfaces (epithelial cells) of the body.
NPCs are of 3 types. They all start from the epithelium, the line that the nasopharynx sells, but each type of cell looks different under a microscope:
Non-keratinizing undifferentiated carcinoma (this is the most common type of NPC in the US.)
Non-keratinizing Differentiated Carcinoma – What Is Nasopharyngeal Cancer ? Nasopharyngeal carcinoma
Keratinizing Squamous Cell Carcinoma
Treatment is the same for all types of NPCs. Non-keratinizing types respond better to treatment, but the stage of cancer – how far it has spread and spread – is often more important than the type predicting a person’s outlook (prognosis).
Many NPCs have a lot of immune system cells, especially white blood cells called lymphocytes. The term lymphophithiola is sometimes used to describe a depressed NPC with multiple lymphocytes among cancer cells. The presence of these cells generally does not affect the choice of treatment option. But they can help researchers develop new treatments, as they can be clues to how the body attempts to fight tumors. (What’s new in nasopharyngeal cancer research?)
Other cancers in the nasopharynx –
Other types of cancer can also be found in the nasopharynx:
Lymphoma can sometimes begin in the nasopharynx. They are cancers of the cells of the immune system called lymphocytes, which are found throughout the body, including the nasopharynx. To learn more, see Non-Hodgkin lymphoma.
Adenocarcinoma and adenoid cystic carcinoma are cancers that can begin in the minor salivary glands in the nasopharynx. But these cancers usually occur in the nose (nasal cavity) or mouth (oral cavity). To learn more about these cancers, see Oral cavity and oropharyngeal cancer, nasal cavity and paranasal sinus cancer or salivary gland cancer.
Benign nasopharyngeal tumor
Benign nasopharyngeal tumors are quite rare and develop in children and young adults. These tumors do not spread to other parts of the body and are generally not life-threatening. They include tumors or malformations of the vascular (blood-carrying) system, such as angiofibromas and hemangiomas, and benign tumors of the minor salivary glands within the nasopharynx.
Benign nasopharyngeal tumors do not always require treatment. When they do, treatment is not the same as for nasopharyngeal cancer. If you have a benign tumor, talk to your doctor about what to expect.
Symptoms of nasopharyngeal cancer may include:
A lump in the neck – What Is Nasopharyngeal Cancer ? Nasopharyngeal carcinoma
Hearing loss – usually only in one ear
Tinnitus – Hearing sound that comes from inside the body rather than from an external source
A blocked or stuffy nose
What Causes Nasopharyngeal Cancer?
The exact cause of nasopharyngeal cancer is unknown, but several factors may increase the risk of developing the condition. Contains:
Is of south chinese or north african origin
Salt diet – Nasopharyngeal Cancer
Being exposed to Epstein-Barr virus (EBV), a common virus that causes glandular fever
Doing a job where you are regularly exposed to hardwood dust
First-degree relatives, such as parents whose condition was.
How is nasopharyngeal cancer treated?
If you are diagnosed with nasopharyngeal cancer, you will be looked after by a team of different specialists who work together in what is called a multi-disciplinary team (MDT). Your MDT members will discuss with you what they think is the best treatment option in your case.
There are two main treatments for nasopharyngeal cancer: What Is Nasopharyngeal Cancer ? Nasopharyngeal carcinoma
Radiotherapy – where radiation is used to kill cancer cells
Chemotherapy – where the drug is used to kill cancer cells
In most cases, a combination of radiotherapy and chemotherapy will be used.
Surgery is not commonly used to treat nasopharyngeal cancer because it is difficult for the surgeon to reach the affected area.
Can nasopharyngeal cancer be cured?
Many cancers of the nasopharynx can be cured, especially if they are found early. The details of the common types of treatments used for NPCs are listed below. Your care plan may also include treatment for symptoms and side effects, an important part of cancer care. The main treatment for NPC is radiation therapy.
Is nasopharyngeal cancer deadly?
The 5-year survival rate for people with NPC is 61%. However, the survival rate depends on many factors, including the location of the tumor and the phase if or where it has spread. If the cancer is only located in the nasopharynx, the 5-year survival rate is 82%. – What Is Nasopharyngeal Cancer ? Nasopharyngeal carcinoma
Is nasopharyngeal cancer painful?
Most people with nasopharyngeal cancer (NPC) notice a lump or mass in the neck that takes them to see a doctor. There may be lumps on the back of either side of the neck. The lump is usually not tender or painful
