Salivary Gland Cancer (Symptoms,Causes and Treatment)
A uncommon kind of cancer called salivary gland cancer appears in the salivary glands, which are found in the head and neck area. Saliva from these glands keeps the mouth wet and aids in digesting. Any salivary gland can develop cancer, but the parotid gland, the largest salivary gland in front of the ear, is where it most frequently manifests. A lump or swelling near the salivary gland, soreness, a challenge opening the mouth or swallowing, facial paralysis or numbness, or fluid pouring from the ear are possible symptoms. Radiation therapy, chemotherapy, and/or surgery to remove the tumor are common forms of treatment. The likelihood of a favorable result for salivary gland cancer varies depending on the kind and stage of the disease, although early detection and treatment can increase those odds.
This article covers the following topics :
What is cancer of the salivary gland?
A uncommon kind of cancer called salivary gland cancer begins in the salivary glands, which are responsible for producing saliva in the mouth and throat. The head and neck region has a variety of salivary gland types, and cancer can arise in any of them. Mucoepidermoid carcinoma, one of the most prevalent types of salivary gland cancer, is also known as adenoid cystic carcinoma, acinic cell carcinoma, and other names.
Although there is no known cause for salivary gland cancer, there are several known risk factors. Among them are advanced age, radiation exposure, a family history of salivary gland cancer, and specific genetic diseases such Cowden syndrome.
A lump or swelling in the mouth, neck, or jaw, pain in the face, mouth, or neck, numbness in the face, trouble swallowing or opening the mouth, a change in the way the face looks or moves, among other symptoms, are all signs of salivary gland cancer.
A physical examination, imaging tests like a CT scan or MRI, and a biopsy to extract a tiny sample of tissue for microscopic analysis are typically used to diagnose salivary gland cancer. Surgery, radiation therapy, and chemotherapy are all potential treatments, depending on the type and stage of cancer.
Salivary gland cancer can be dangerous and even fatal, like many other malignancies. The prognosis and outcome, however, rely on a number of variables, such as the disease’s stage, the type of salivary gland cancer, and the patient’s general condition.
It is crucial to speak with your doctor if you are experiencing signs of salivary gland cancer or are worried about your risk. They may assist you in identifying your risk factors, offer advice on screening and prevention measures, and, if necessary, go over your treatment options.
How prevalent is cancer of the salivary glands?
Less than 1% of all malignancies are salivary gland cancers, making them relatively uncommon. In the United States, it affects 2 to 3 persons out of every 100,000 people annually. Depending on the cancer’s form and where it develops inside the salivary gland, the incidence of salivary gland cancer varies.
Who is at risk for cancer of the salivary glands?
Anyone can get salivary gland cancer, although it is more common in older people and those who have been exposed to particular risk factors. Older age: Adults over the age of 50 are more likely to get salivary gland cancer than younger adults.
*Gender: Men are slightly more likely than women to have salivary gland cancer.
*Radiation exposure: People who have had radiation therapy to the head and neck region are more likely to develop cancer of the salivary glands.
*Occupational exposure: Some jobs, such as those that require exposure to specific chemicals or substances, may raise the risk of salivary gland cancer.
*Family history: Adenomatous polyposis, a rare genetic disorder, may raise the risk of salivary gland cancer.
However, the origin of cancer of the salivary glands is frequently unknown.
Why do salivary glands develop cancer?
Cancer of the salivary glands has an unknown specific origin. However, a few things can make you more likely to get cancer of the salivary glands. These consist of:
1-Age: People over the age of 50 are more likely to get salivary gland cancer.
2-Gender: Cancer of the salivary gland is more common in men than in women.
3-Radiation exposure: Those who have undergone head and neck radiation therapy are more likely to acquire salivary gland cancer.
4-Family history: This cancer may be more likely to occur in those who have a history of salivary gland cancer or certain inherited disorders.
5-Workplace exposure: Salivary gland cancer risk may be higher for persons who work in particular vocations that expose them to radioactive materials or specific chemicals.
It is crucial to remember that a risk factor does not guarantee that a person will acquire salivary gland cancer; in fact, many individuals with the disease have no recognized risk factors.
What signs indicate malignancy of the salivary glands?
The location and size of the tumor can affect the symptoms of salivary gland cancer. Some such signs could be:
1-A lump or swelling that may or may not be uncomfortable in the mouth, neck, or face
2-Facial or jaw numbness or weakness
3-Difficulty speaking or swallowing
4-Continuous discomfort in the ear, neck, or mouth
5-Weakness or paralysis of the facial muscles
6-Modifications in the sensation in the face, such as tingling or a pins-and-needles feeling
7-Continual hoarseness or other vocal alterations
8-Swelling of the neck’s lymph nodes
9-Having trouble expanding your mouth
It is crucial to remember that these symptoms might also be a sign of other ailments, necessitating a medical assessment for an accurate diagnosis.
How is cancer of the salivary glands detected?
Typically, a combination of a medical history, physical examination, and diagnostic tests is used to identify salivary gland cancer. An examination of the head and neck by a medical professional may be done to look for tumors, edema, or other abnormalities. To check for tumors or other indications of cancer, imaging tests like CT scans, MRIs, or PET scans may also be used.
Typically, a biopsy is required to establish the presence of salivary gland cancer. A salivary gland sample is extracted during a biopsy, and the tissue is inspected under a microscope to look for malignant cells. The tissue will be examined by a pathologist to ascertain the kind and stage of malignancy.
The extent of the cancer may be determined by other testing, such as blood tests or a chest X-ray to look for cancer spread to other body parts.
What stage of salivary gland cancer is it?
The Tumor, Node, and Metastasis (TNM) approach is used to stage salivary gland cancer. Utilizing this technique, it is possible to determine the size and scope of the main tumor (T), if the cancer has progressed to the lymph nodes (N), and whether it has metastasized, or spread to other body areas (M).
The tumor’s size and the extent of its tissue invasion determine the T category. T4 tumors are huge and have spread into neighboring structures like bone or muscle, whereas T1 tumors are small and have not spread into nearby structures.
Based on whether cancer has spread to surrounding lymph nodes, the N category is assigned. N0 denotes the absence of any indication of lymph node involvement, whereas N3 denotes the spread of the malignancy to nearby lymph nodes or lymph nodes on the other side of the body.
The M classification is based on whether cancer has spread to other organ systems. M0 denotes the absence of distant metastasis, whereas M1 denotes the spread of malignancy to distant organs or tissues.
The total stage of cancer, which ranges from stage I (early) to stage IV (advanced), is determined by combining the T, N, and M categories. The cancer stage gives clinicians an idea of the patient’s prognosis and aids in choosing the best course of treatment.
How is cancer of the salivary glands treated?
The type of cancer, its stage, its location, and the patient’s general health are just a few of the variables that affect how salivary gland cancer is treated. The primary forms of treatment are:
1-The most frequent form of treatment for cancer of the salivary glands is surgery. The aim of surgery is to remove the tumor and any lymph nodes that are involved. In some circumstances, a piece of the salivary gland in question would also need to be removed.
2-Radiation therapy: High-energy beams are used in radiation therapy to destroy cancer cells. Small tumors may be treated with it as their main course of action, or after surgery to eradicate any cancer cells that may have survived.
3-Chemotherapy is the use of medications to destroy cancer cells. It could be used with radiation treatment or surgery.
4-Targeted therapy: Drugs that specifically target chemicals that promote the growth of cancer cells are used in targeted therapy. In some cases of salivary gland cancer that have not responded to other treatments, it may be employed.
5-Palliative care aims to enhance the quality of life for cancer patients who have advanced disease. It could include symptom reduction, pain management, and emotional support.
A group of medical experts, including an oncologist, surgeon, and radiation therapist, will decide on the course of therapy.
What problems are linked to benign tumors of the salivary glands?
Complications from benign salivary gland tumors include:
*Enlargement: Depending on the tumor’s size, the gland may expand and enlarge, which can make it uncomfortable and difficult to breathe, speak, or eat.
*Recurrence: Even after being medically removed, some benign tumors can come back. This occurs because the initial operation may not have completely eliminated the tumor.
*Infection: A tumor that blocks a salivary gland’s ducts increases the likelihood of a bacterial infection.
Although uncommon, some benign tumors have the potential to develop into malignant ones over time. It’s crucial to frequently check on benign tumors to make sure they don’t develop into cancerous ones.
The majority of benign salivary gland tumors have a favorable prognosis and pose few serious risks. But if you feel any signs or pain, you must visit a doctor right away.
Can cancer of the salivary glands be prevented?
Salivary gland cancer cannot be prevented, as far as is known. However, some risk factors, like using tobacco and drinking too much alcohol, can be avoided or managed to lower the risk of developing salivary gland cancer. Furthermore, shielding the head and neck from radiation exposure may lessen the chance of developing cancer of the salivary glands. Regular dental exams may aid in the early diagnosis of any abnormalities in the salivary glands.
Can cancer of the salivary glands be cured?
The stage and kind of the disease, the patient’s general health, and the available treatment options all affect the likelihood of a patient surviving salivary gland cancer. A higher percentage of early-stage tumors that have not progressed to other body parts are cured. Surgery, radiation therapy, and occasionally chemotherapy are the most common forms of treatment for salivary gland cancer. A combination of these therapies may be applied in some situations. Salivary gland cancer has a five-year overall survival rate of about 75%, but this varies greatly depending on the precise kind and stage of cancer. It is significant to remember that early detection and treatment might raise the likelihood of a positive result.
What is the prognosis for cancer of the salivary glands?
Salivary gland cancer survival rates are influenced by a number of variables, such as the cancer’s stage, its location, its size, and its kind. The American Cancer Society reports the following 5-year survival rates for persons with salivary gland cancer:
Approximately 91% of persons with localized cancer (cancer that has not progressed past the salivary glands) and 72% of those with regional cancer (cancer that has spread to adjacent lymph nodes) live for at least 5 years following diagnosis, respectively.
Approximately 39% of persons with distant cancer (cancer that has spread to distant organs or tissues) survive for at least 5 years after diagnosis.
It’s crucial to remember that these survival rates are averages and could not be a reliable indicator of a person’s prognosis. The best approach to comprehend your prognosis is to speak with your doctor, who can consider your unique circumstances and medical background.
When should I call my doctor if I have cancer of the salivary glands?
If you have any symptoms, such as a lump or swelling in your mouth, face, or neck, trouble swallowing or opening your mouth, numbness or weakness in your face, or chronic pain in your mouth or throat, you should consult a doctor. Additionally, if you have any worries about your chance of developing salivary gland cancer, particularly if you have a family history of the condition or have had radiation exposure to the head or neck area, you should visit your doctor. If you observe any changes in your salivary glands, you should consult a doctor right away because fast diagnosis and treatment can enhance your prognosis.
