Tumors can occur in any gland , but parotid secreter have a gamy relative incidence of developing unnatural increase of cells . Although most case are benignant , some benignant Cancer can become malignant over time.1
Benign tumors grow slowly and do not metastasize , but the incidence of malignant transmutation increases with the duration of the tumor.2
The sizing of parotid tumors often depend on the phase and tumour size is measured in centimeters . Tumors can farm as heavy and invade the arteries.3 , 4
Can Benign Parotid Tumors Become Malignant?
Parotid neoplasm account for 80 % of salivary gland Cancer the Crab and out of which 20 % of slip turn malignant . neoplasm can hap in any glands , but parotid glands have a high incidence of prepare abnormal growth of cells . Although most cases are benignant , some benignant Cancer can become malignant over time.1
They shape a swelling or lump near the jaw , impudence , or in front of the ears . In the steady clinical practice , the parotid wad are remove through surgical resection for the direction of the facial heart . A medical study was transmit on 540 patients who underwent surgery for the remotion of the parotid gland . The diagnosing of these patient showed that 470 cases were non - cancerous ( benignant ) and 70 cases were malignant .
The recurrence of benignant tumors had a higher incidence when compared to the malignant fount that were removed by parotidectomy . benignant tumors produce lento with painless masses in the tail of the parotid gland and do not metastasise , but the incidence of malignant transformation increases with the continuance of the tumour . Pleomorphic adenoma is the Graeco-Roman case of a benign tumor and mucoepidermoid carcinoma is the most coarse malignant tumor.2
How Big Are Parotid Tumors?
The TNM system is the most commonly used staging organisation for Crab . The point are often free-base on symptomatic mental testing and imaging studies .
T ( Tumor ) – The size of it of the tumor and determine whether it has spread to the nearby tissues
N ( Node ) – touch on to the regional lymph lymph gland metastasis . Where and how it has spread .
M ( Metastases)-whether or not it has circularise to other part of the body such as the lungs .
The results are combined to key out the point of cancer for every individual . Stages are classified from 0 through 4 and each leg shows the growth and size of cancer . The size of parotid tumors often calculate on the stages and tumor size of it is measured in centimeters . Tumors can grow as big and invade the arteries . There is no grounds of malignancy when the tumor level is T0 . The neoplasm grows up to 2 cm when they are T1 level . The neoplasm grows gravid and encroaching during stage T2 .
During the T3 stage , the tumour grow larger than 6 centimetre and circulate to remote parts of the organ beyond the salivary gland and affects the 7th cranial nerve.3 , 4
Both benignant and malignant tumors can explicate anywhere in the salivary gland , but parotid gland have an increase peril of developing this circumstance . The parotid glands are the expectant salivary glands sit in front of the auricle .
sure broker such as dehydration , smoking , photo to radiation sickness enhance the risk of develop parotid tumors . The majority of the salivary gland tumors are non - cancerous and may decide without treatment . But some may turn malignant and have persistent pain in the area of the salivary secretory organ .
