The throat can be classified into different type according to the place of occurrence. It is classified as vocal cord cancer, laryngeal cancer, thyroid cancer, nasopharyngeal cancer and the hypo pharyngeal cancer. The thyroid is part of the base of the neck. The thyroid gland cancer is the rare type. The pharyngeal and the laryngeal is the most common.
The main cause for the throat cancer is found as the usage of tobacco. The consumption of the tobacco in any form leads to throat cancer. Contradictory to the other cancer where the consumption of the tobacco in smoke-less form reduces the chance of the cancer, the same is not true in throat cancer. Using tobacco in smoke-less form has negative impact in throat cancer. It cause the same way as the smoking causes.
The thyroid gland cancer is a type of throat cancer in which the thyroid gland may grow abnormally leading to the formation of tumors. The thyroid is a gland that is located at the base of the throat. The main purpose of this gland is to secrete hormones that regulate many parts of the body.
If you want to know whether or not you have throat cancer, you should familiarize yourself with some of the symptoms that might appear. If the symptoms are detected early enough, the throat cancer can be successfully treated. The purpose of the treatment will be to destroy the cancerous cells before they spread to the other parts of the body.
Most head and neck cancer cells are squamous, which means they do not travel far from their origin, although they often affect the lymph nodes. In fact, the first indication of head or throat cancer is often an enlarged neck lymph node, which is also sometimes referred to as throat cancer.
Causes
The tobacco is found to be the most common cause for the throat cancer. It damages the cells in the oral cavity and the inner part of the throat. The risk is high for the smokers when compared to normal people. The statistics says the ninety percent of the people suffering from it are smokers.
The excessive consumption of alcohol also leads to throat cancer. It also damages the cell inside the throat and the path to the esophagus. The statistic says about seventy five of the people suffering are frequent drinkers of alcohol.
The exposure to the ultraviolet light may cause damages to the cells in the lips and in the upper part of the throat. The continual exposure may lead to throat cancer. The statistics says one in three people suffering have jobs that make them to the exposure to uv rays.

Less obvious symptoms of throat, head and neck cancer can include feeling like your headache never goes away, having a hard time taking a deep breath, noticing that your nose bleeds all the time, tooth pain, and unexplained swelling in general throat area.
Medical researchers have been unable to identify the precise cause of throat cancer. However, they have been able to determine that tobacco can cause damage to the cells in the lining of the throat. A tumor can form if enough of these damaged cells accumulate.
Treatments
The ultrasound scan is used to find the exact size and nature of the tumor present. The scan uses transducer to use the combined high-frequency sound waves and the computer processing to produce the image. The transducer is wand like object used in this method.
The tissues that consume more energy in the body will absorb more radioactive tracer when sent inside the body. The tumor will also absorb more tracer. This method is applied in the Positron Emission Tomography to find the tumor in the body. The PET scan uses a small amount of a radioactive tracer for the above process.
The exact extent of the cancer in the throat can be determined by this MRI scan. The MRI scan is also used to find the involvement of the lymph nodes in the cancer. The MRI scan produces image that can be viewed from any direction. The above process needs magnetic field and the use of the radio waves.
the x-ray gives the image of the mouth, head and chest in one-dimensional.
The throat cancer is classified into different stages based on the condition of the cancer. The stage of the cancer plays important role in the diagnosis part. The treatment is carried out depending on the current stage of the cancer.
In stage two the cancer remains in the area where it has started but it must have grown in size than in stage one.In stage three the cancer will spread out to the near-by areas and the effect of the cancer is felt in the area it has started. The symptoms of the cancer are easily found in this stage.
