In the United States where nasopharyngeal cancer (NPC) is rare, and doctors do not ask for routine screening for this type of cancer. (Screening tests are tests for cancer in people who have no symptoms.) There are no simple tests or blood tests that can detect this cancer early. However, regular check-ups and visits to the dentist are recommended. Check the throat, mouth and nose. In these visits.
But in some parts of the world, such as China, and NPC cancer blood test hong kong, where NPC is more common, and some people will routinely check for this cancer. They were initially selected because their blood showed evidence of Epstein-Barr virus (EBV) infection, although EBV infection is more common than NPC. You will undergo regular nasopharyngeal and throat examinations at Take2 Health. If the member has a well-developed NPC, this method can also be used in the family. It is not clear whether this will reduce the death toll of NPCs or not.
The symptoms and signs of nasopharyngeal carcinoma:
The nasopharyngeal carcinoma often shows palpable lymph node metastases in the neck area. Another common symptom is hearing loss, which is usually caused by a blockage of the nasal cavity or Eustachian tube causing fluid in the middle ear. The other symptom is an earache. Suppurative bloody rhinorrhea, obvious epistaxis, cranial nerve palsy, and cervical lymphadenopathy. The most common route of intracranial spread of these tumors. So, you need to take an NPC cancer blood test hong kong. Because the lymphatic vessels of the nasopharynx communicate through the midline, bilateral metastases are common.
Causes of nasopharyngeal cancer:
Scientists are not sure what causes nasopharyngeal cancer. However, cancer is closely related to the Epstein-Barr virus (EBV).
Although EBV infection is common, not everyone with EBV infection will develop nasopharyngeal cancer. In the United States, most EBV patients never have long-term problems. The genetic material (DNA) of the virus, which affects the DNA in the nasopharyngeal cells. Changes in DNA can cause abnormal cell growth and division, which can lead to cancer.
A diet rich in meat and salted fish increases the risk of NPC. Tobacco and alcohol also increase risk, but their relationship with NPC is unclear, so you need to check up at take2 health for NPC cancer blood test.
Risk factors for nasopharyngeal cancer:
Epstein-Barr virus (EBV) infection may increase the risk of nasopharyngeal cancer. EBV is spread through body fluids, including saliva. Most people are infected with EBV at some point in their lives. , The body fights the virus, but the infection is ignored. In the United States, EBV is known to cause mononucleosis.
For reasons that are not fully understood, people living in North Africa, Southeast Asia, and southern China are at increased risk of nasopharyngeal cancer if they are infected with EBV. Since New York is the home of new immigrants from these areas, compared with other medical centers in the United States, the number of nasopharyngeal cancer patients diagnosed and treated by doctors at New York University Langone is large.
How is nasopharyngeal cancer diagnosed?
Your doctor may use endoscopy to detect cancer. In this test at take2 health, a thin tube with a very small cavity is placed at the end of the nose. This allows doctors to become more familiar with cancer.
During the endoscopy, your doctor may take a small part of the tumor, called a biopsy, and then send some of the tumors to the laboratory for observation under a microscope.
Your doctor may also recommend an MRI (magnetic resonance imaging) scan. This MRI takes special pictures of the nasopharynx so that the doctor can determine the size of the tumor.
Complications of nasopharyngeal carcinoma can be:
Cancer that grows and affects nearby structures. If advanced nasopharyngeal cancer grows large enough to affect nearby structures such as the bones, throat, and brain, it can cause complications.
Cancer has spread to other parts of the body. Nasopharyngeal cancer often spreads (metastasis) outside the nasopharynx.
Most patients with nasopharyngeal cancer have local metastases, which means that cancer cells have migrated from the original tumor to nearby areas, such as the lymph nodes in the neck so, NPC cancer blood test hong kong is best for the check at early stages.
Cancer cells that have spread to other parts of the body (distant metastases) usually metastasize to the bones, lungs, and liver.
Patients and methods:
The participants with persistently positive EBV DNA underwent endoscopy and biopsy for suspected NPC, followed by MRI, but no endoscopy results. Participants with negative endoscopy and positive MRI were asked to undergo a biopsy or observation. The sensitivity, specificity, and accuracy are calculated at take2 heath based on the histological confirmation of the PCN in the initial study or at least two years of follow-up.
Nasopharyngeal Cancer Test:
History and Physical Examination:
If you have any signs or symptoms that you have NPC, your doctor will ask you to provide a complete medical history. You will be asked about the changes you noticed, possible risk factors, and family history.
A medical examination will be performed for signs of NPC or other health problems. Perform a more comprehensive examination of the nasopharynx. During the examination, your doctor will pay special attention to your head and neck, including your nose, mouth, and throat; your facial muscles; and neck lymph nodes. A hearing test can also be done.
You and your doctor will make a treatment plan based on several factors, such as your cancer stage, your treatment goals, your overall health, and the side effects you want to endure.
The treatment of nasopharyngeal carcinoma usually starts with radiation therapy or a combination of radiation and chemotherapy.
The following tests can be used to diagnose NPC:
Physical examination and NPC cancer blood test hong kong During the physical examination, the doctor will feel any lumps on the gums, neck, lips, and cheeks. The doctor at take2 health will look for abnormalities in the nose. Mouth, throat, and tongue, usually with lights and/or mirrors for clearer vision. At the same time, blood tests can be performed to detect the presence of antibodies against the EBV virus. For more information about EBV, see the prevention and risk factors section.
Endoscopy: Endoscopy allows doctors to look inside the body using a thin and flexible light-emitting tube called an endoscope. When a tube is inserted through the mouth or nose to examine the head and neck area, the person may be given a sedative. Take medicines that make you more relaxed, calmer, or sleepy. When endoscopy is performed to examine the nasopharynx, it is called a nasopharyngoscopy.
Biopsy: A biopsy is the removal of a small amount of tissue for examination under a microscope. Other NPC cancer blood test in hong kong may indicate cancer, but only a biopsy can make a definite diagnosis. The pathologist then analyzes the sample. A pathologist is a doctor who specializes in interpreting laboratory tests and evaluating cells, tissues, and organs to diagnose diseases. The type of biopsy depends on the location of cancer.
