Nasopharyngeal cancer
What is cancer?
The human body consists of billions of cells, and in their non-disabled people, these cells grow and multiply and then die. Replace old cells new cells are constantly and regularly, Tzmn this process for each member of the body number and the appropriate type of cells to good health.
The cancer cells are multiplying faster than normal cells do not function as normal. They are not human does not work, but may produce toxic materials in some cases, may displace normal cells and compete on the sources of the body.
Ttsrtun cells being destroyed when its contents of the DNA. DNA contains the instructions needed by cells to divide and function only. People may inherit this DNA Almtadmr; making them more susceptible than others to the development of cancer cells. Also, the DNA was being destroyed because of exposure to toxic environmental factors such as substances found in tobacco, and this is likely.
With the increasing number of these cancer cells; they are the so-called tumor cancerous, and if this Mastmr tumor growth; it invades and destroys the tissue around it, which has spread to other distant places in the body, forming new tumors, the so-called spread.
These cells must be killed or removed before it spreads and destroys only the members of the important and vital in the body.
What is the nasopharynx?
Nasopharynx is located in the region far behind the nose.
What is nasopharyngeal cancer?
Cancer occurs when cells Ttsrtun throat and begins to reproduce and, unfortunately, is often detected after the cancer has spread.
Risk factors:
Risk factors are all that makes a person more likely to develop the disease than others, those factors may be:
Inherited: Kdjinat Almtadmrh in DNA.
Environmental: such as living in areas contaminated air.
Has a link to social life and lifestyle: Ktdkhin tobacco.
The more risk factors in humans has become more vulnerable to disease progression.
Associated with nasopharyngeal cancer is closely linked to HIV Abashtan - Barr, where the cause of the virus in the proliferation of the cells out of control in that region. It was also noted that this virus does not cause the development of cancer in all patients do, but for unknown reasons. Also it was noted that this virus infects Asian ethnic more than others, and that explains the presence of cancer as well as the Asian races more than others.
Symptoms and signs:
Most of the symptoms associated with this cancer are nasal symptoms, including:
Epistaxis.
Stuffy nose.
Increase in nasal secretions.
There is also other non-nasal symptoms, including:
Hearing loss or ringing in the ear.
Headache.
Tumors in the neck.
Diagnosis:
Be sure to diagnose the disease before starting any treatment, and that by taking a small tissue sample from the tumor and examined under a microscope.
As well as doctors may need to make some tests to make sure the body free of any spread of the disease, including CT scans and magnetic, which inform doctors a complete picture of the inside of the body. As well as doctors need to examine a comprehensive head and neck when the suspicion of cancer, and that includes the examination of the mouth, throat and neck, was forced to shoot any of that camera, if necessary.
Mattresses Cancer
Cancer doctors ranked based on its size and spread, this arrangement may be more complex in some cancers. As a general rule on each case, the higher the status of cancer, indicates that the size of the tumor and its spread is greater. For example, the number one cancer that is smaller in relative has not spread from its original location, in contrast, cancer ranked fourth be relatively large, has spread to places far from its original location.
Treatment:
About:
Most cancers are treated with surgery or radiation or chemotherapy, and often have a mix of that. Since each patient is unique in itself, there is no uniform treatment plan is ideal for all. So, the doctor will prescribe the most appropriate treatment for each patient, based on the ranking of cancer, health status and medical history of the patient.
Surgery:
Must often remove the cancer surgically. And adopt the seriousness of the process and the volume of tissue cleared of cancer and the rank of members affected by other factors such as the situation and the general health of the patient. Surgery is usually effective, but may follow other means of treatment, to ensure the elimination of all cancer cells.
Radiation therapy:
Where doctors used highly concentrated radioactive packages, to kill cancer cells while preserving normal cells as possible. Radiation therapy does not cause any pain at all, but since the radiation therapy may kill cells together close to cancer cells may cause some side effects.
Side effects of radiation therapy:
Skin problems: there may be redness or itching, but it disappears at the end of treatment.
Fatigue: Many patients feel very sick as a result of treatment.
Loss of appetite, as well as radiation therapy and other treatment methods and psychological stress may lead to loss of appetite, but it is important that the patient is well nourished during treatment.
Hair loss: Radiation therapy may cause loss of hair, so ask your doctor about your condition.
Chemotherapy:
Injected anti-cancer or given by mouth. These treatments are designed to look for cancer cells and kill them, but may kill some of the normal cells, causing some side effects such as:
Nausea.
Vomiting.
Loss of appetite.
Hair loss.
Mouth ulcers.
Anti-cancer affects the bone marrow - where blood is made - and that leads to a decrease in blood cells, resulting in:
Vulnerability.
Bruises.
Bleeding from the lower wound.
Shortness of breath.
Fatigue.
Weakness.
Most of these symptoms go away after the end of treatment.
