Saliva gland tumor

Saliva gland tumor's disease overview

Saliva glands are abnormal growth in the salivary glands. The salivary gland is located at the back of the oral cavity and is responsible for secretion of saliva to help the body digest food. The main salivary gland includes an ear gland (located on both sides of the face), the lower jaw and the lower tongue. The secondary glands start from the palate and lie along the oral cavity, sinuses, nose. These routes can only be seen under a microscope.

Saliva tumors account for about 0.2 - 0.6 % of tumors and 2-4 % of the head tumors. The annual incidence of salivary glands worldwide is about 0.4 - 6.5 shifts/100,000 people.

In Vietnam, there are about 0.6 to 0.7 new salivary glands/100,000 people. The salivary glands are mainly found in the main salivary glands, of which the ear tumor is 70%, the lower gland is 8%, the remaining 22%is seen at the lower tongue and the auxiliary salivary glands. Up to 75% of the ear gland tumor is benign, 50% of the lower gland tumor and 80% of the auxiliary salivary glands are found to be malignant.

Is the salivary glands contagious ? Saliva glands are not transmitted from one person to another. Treatment of salivary tumor is often associated with surgery. Treatment for salivary tumors may also include radiation and chemotherapy.

Causes of Saliva gland tumor's disease

Saliva tumors are very rare, accounting for less than 10 percent of all head and neck tumors. The cause of the salivary tumor.

Studies show that salivary cancer occurs when some cells in the salivary glands grow mutant in their DNA. Mutations allow cells to grow and divide quickly. Mutations continue to live when other cells die. The accumulated cells form a nearby tissue invasive tumor. Cancer cells can break and spread (metastases) to remote areas of the body.

Symptoms of Saliva gland tumor's disease

Mechanical symptoms

Symptoms of salivary glands are often poor, manifested as a tumor under the jaw, neck (gland under the jaw), on the corner of the jaw or on the face (ear gland), swollen blocks Up at the mouth floor (lower tongue).

Characteristics of u: appear for a long time, progress slowly, may not be painful, if the pain in the tumor area suggests is malignant tumor. The tumor can increase rapidly due to inflammation, bleeding in the tumor.

About the location of the auxiliary salivary glands and glands can be seen in many places, each tumor in different positions will cause different symptoms. Bleeding or stuffy nose may be the first sign of the extra salivary tumor at the nasal septum. While the tumors at the bottom of the tongue cause swallowing and choking. The tumors in the mouth can cause the jaw ...

physical symptoms

benign: Round u, clear boundaries, density, mobile; When tumors are deep, fibrosis is limited; There are no signs of nerve or skin invasion.

Malignant: Hard, firm, unknown boundaries, limited or fixed cells when tumors invade the muscles or lower jaw bone, can cause slight paralysis of the lower lip, Skin invasive skin or skin ulcers, can metastasize neck lymph nodes or lung metastases, bones.

Subclinical symptoms

ultrasound: is an easy -to -do method, high value in diagnosis; Contributing to confirming the clinical diagnosis, locating the tumor in the parenchyma or outside the gland, thick tumor or cyst, tumor or lymphadenopathy. In some cases, ultrasound can bring some information to help distinguish healing with evil tumors. Benign tumors often have a homogeneous, clear shore. Evil tumors often have a heterogeneous sound density, irregular shore and can be necrotic.

Computerized or magnetic resonance imaging: These imaging methods bring a lot of information in the evaluation of salivary gland disease, density, size, size U, boundaries, invasive tumors into the surrounding organization. The adding magnetic shooting is beneficial for the image of three -dimensional space between the gland and normal tissue, does not increase the size of the tumor due to X -rays

Small needle cell suction: This method contributes to distinguishing gland inflammation, tumor, adjacent lymph nodes.

People at risk for Saliva gland tumor's disease

Old age: The salivary tumor can occur at any age, but they most often occur in the elderly.

Contact with radiation. Radiation, such as radiation used to treat head and neck cancer, increases the risk of salivary tumors.

Workplace contact with some substances. People who work with some substances may increase the risk of salivary tumors. Works related to salivary tumors include tasks related to rubber production, asbestos and water pipe systems.

Exposure to viruses makes you at risk of salivary gland cancer including HIV and RBV virus (Epstein-BARR)

Treatment I131 can increase the rate of salivary glands

Abuse of dental X -ray or X -ray of the head area may be a factor that promotes the onset of tumor.

Alcohol and tobacco abuse: Some recent studies show that the abuse of alcohol and tobacco is related to U Warthin (lymphoma).

Poor environmental pollution, poor nutrition also contributes to increasing the risk of salivary glands.

Prevention of Saliva gland tumor's disease

Limit drinking, beer, smoking

Provide daily nutrition

Diagnostic measures for Saliva gland tumor's disease

Diagnosis of salivary gland tumor includes:

Clinical examination: The doctor will feel your jaw, neck and neck clump or swelling.

Image tests: Image tests, such as magnetic resonance imaging (MRI) and computer -layer cutting (CT), can help determine the size and taste The mind of the salivary tumor

Biopsy: Take a sample of a tumor to test in the laboratory to determine whether the tumor is cancer.

Determine the level of salivary cancer: If diagnosed with salivary gland cancer, the doctor will determine the level (stage) of cancer. P>

Saliva gland tumor's disease treatments

The best treatment for salivary tumors is surgery, test tissue test. The widest removal is due to the decisive tissue and anatomical characteristics.

Honesty glands: benign tumor shallow or deep lobe but need to preserve VII nerves. Malignant tumor depending on the size and invasion that decides to cut the shallow lobe or cut the entire line and the VII wire.

Health or malignant jaw glands also need to remove the gland. If clinically, lymphadenopathy needs to dredge.

The lower tongue gland: remove the entire tumor and organize the gland, avoid damaging the oral floor.

Treatment of salivary tumors depends on the type, size and stage of the salivary tumor including surgery, with or without radiation.Surgery surgery for salivary tumors may include:

Eliminate part of the salivary glands affected.

Remove the entire salivary glands in the case of a larger tumor

Remove lymph nodes in the neck if there is evidence that the cancer has spread to the lymph nodes in the neck

Surgical surgery. After surgery to remove the tumor, the doctor may recommend regenerating surgery to repair the area. In the process of reconstructive surgery, the surgeon works to improve the ability to chew, swallow, speak or breathe, may need skin, tissue or nerve grafting from other parts of the body to build Restores areas in your mouth, throat or jaw.

Salivary surgery may be difficult because some important nerves are inside and around the glands. Eliminating tumors related to important nerves may require damage to nerves, partial anesthesia of your face (drooping). The surgeon takes care to preserve these nerves whenever possible. In some cases, broken nerves can be repaired with nerves taken from other areas of the body.

Radiation therapy

Radiation therapy when diagnosed with salivary gland cancer, using strong energy beams, such as X -rays and protons, to kill cancer cells. P>

A newer radiation using particles called neutrons can be more effective in treating some salivary gland cancer. More research is needed to understand the benefits and risks of this treatment.

Radiation therapy can be used after surgery to destroy any remaining cancer cells. If surgery is not possible because a very large tumor or in a place that makes it too risky, the doctor may recommend radiation alone or in combination with chemotherapy.

Chemotherapy

chemotherapy is a chemical drug to kill cancer cells. Chemotherapy is not used as a standard treatment for salivary gland cancer, but researchers are researching and using it.

Chemotherapy can be an option for people with salivary gland cancer. Sometimes it is used in combination with radiation.

Monitoring treatment

Re -examination on schedule to monitor the progression of the tumor as well as the recurrence of the tumor after treatment;

Regular tests as directed by the doctor to detect cancer as soon as possible.

Nutrition supplements and drinking plenty of water.
