Can parotid cancer spread to the brain?

Where does parotid cancer metastasis to?
The tumor is any size and cancer may have spread to soft tissue around the salivary gland or to the skin, jawbone, ear canal, and/or facial nerve.
Is parotid cancer aggressive?
Importance Salivary duct carcinoma is a rare, aggressive malignancy of the salivary glands. Owing to its rare nature, clinical data are limited, and only a few clinical studies comprise more than 50 patients.
Can cancer of the parotid gland be cured?
Many salivary gland cancers can often be cured, especially if found early. Although curing the cancer is the primary goal of treatment, preserving the function of the nearby nerves, organs, and tissues is also very important.
What cancer spreads to the parotid gland?
Squamous cell carcinomas are generally the most frequent carcinomas metastasising into the parotid gland 1 3 5 6 14 16.
Does Salivary gland cancer spread quickly?
Grade 1 (low-grade) cancers have the best chance of being cured. They grow slowly and don’t look much different than normal cells. Grade 2 cancers grow moderately fast. Grade 3 cancers grow quickly.
Are parotid tumors fatal?
If cancer is located only in the salivary gland, the 5-year survival rate is 95%. If the cancer has spread outside the salivary gland to nearby structures or lymph nodes, the 5-year survival rate is 69%. If it is found after the cancer has spread to distant parts of the body, the 5-year survival rate is 44%.
What is the most common malignant tumor of the parotid gland?
Mucoepidermoid carcinoma Mucoepidermoid carcinomas are the most common type of salivary gland cancer. Most start in the parotid glands. They develop less often in the submandibular glands or in minor salivary glands inside the mouth. These cancers are usually low grade, but they can also be intermediate or high grade.

What is the survival rate for parotid gland cancer?
Only about 20% of parotid gland tumors are malignant. Half of submandibular and sublingual tumors, and 20% of the minor salivary gland tumors are benign . The five-year relative survival rate for salivary gland cancer depends on the stage the cancer. From Stage I to IV, the rates are 96%, 77%, 73%, and 37%, respectively .
What kind of tumors are in the parotid glands?
The parotid glands are one set of three pairs of major salivary glands. Each set of glands has its own tube (duct) leading from the gland to the mouth. Parotid tumors are abnormal growths of cells (tumors) that form in the parotid glands.
How is radiation therapy used to treat parotid cancer?
Radiation therapy uses powerful beams of energy, such as X-rays, protons or neutrons, to kill cancer cells. If your parotid tumor is cancerous, radiation therapy might be recommended after surgery to kill any cancer cells that remain. Radiation therapy is sometimes used as an initial treatment when surgery isn’t an option.
