Is parotid cancer slow growing?
Most parotid gland cancers are slow-growing and treatable if found in the early stage. Prognosis varies according to histologic type and stage. A combination of radiation therapy and surgery is usually applied to treat this malignant tumor.
What do parotid tumors feel like?
A lump or swelling on or near your jaw or in your neck or mouth. Numbness in part of your face. Muscle weakness on one side of your face. Persistent pain in the area of a salivary gland.
How fast does parotid cancer grow?
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.
What percentage of parotid tumors are malignant?
Parotid Gland 75% percent of parotid tumors are benign*; 25% are malignant. *Although approximately 75% are benign, this number is high because a large number of parotid tumors are composed of supporting cell tumors like muscle (myomas), fat (lipomas), and blood and lymphatic vessels (hemangiomas/lymphangiomas).
Can you survive parotid cancer?
These numbers are based on people diagnosed with salivary gland cancer between 2011 and 2017….5-year relative survival rates for salivary gland cancer.
| SEER Stage | 5-year Relative Survival Rate |
|---|---|
| Localized | 94% |
| Regional | 67% |
| Distant | 44% |
| All SEER stages combined | 75% |
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 parotid tumor?

How aggressive is parotid cancer?
It is the commonest salivary neoplasm in children. Low-grade or well-differentiated tumors usually behave benignly, intermediate ones are more aggressive and high-grade, or undifferentiated tumors metastasize early to regional lymph nodes and carry a poor prognosis.
How big are parotid tumors?
The parotid gland (PG) is the most common site involved in 85% of cases. PG tumors’ size varies from a few millimeters to several centimeters and is about 2-6 cm on average. However, because of insidious growth and asymptomatic nature, untreated tumors of the PG can attain large size.
Do parotid tumors hurt?
