1. 80-90% of parotid tumors are malignant
2. 90% of sublingual gland tumors are malignant
3. 60-70% of submandibular gland tumors are benign

Select the correct answer using the code given below:
Salivary Gland Neoplasms Statement Analysis
This question requires evaluating the accuracy of four statements concerning salivary gland tumors, focusing on malignancy rates and common locations.
Statement 1: Parotid Tumor Malignancy
Statement 1 claims that 80-90% of parotid tumors are malignant. This is incorrect. The parotid gland is the most frequent site for salivary gland tumors, but the vast majority, approximately 70-80%, are benign. Malignant tumors constitute only about 20-30% of parotid neoplasms.
Statement 2: Sublingual Tumor Malignancy
Statement 2 asserts that 90% of sublingual gland tumors are malignant. This statement is considered correct. Although rare, sublingual gland tumors exhibit a high rate of malignancy, frequently reported between 70% and 90%.
Statement 3: Submandibular Tumor Benign Rate
Statement 3 indicates that 60-70% of submandibular gland tumors are benign. This is accurate. Statistics typically show that benign tumors constitute about 50-60% of submandibular neoplasms, with the possibility of this percentage reaching slightly higher in certain studies.
Statement 4: Parotid Gland as Common Site
Statement 4 correctly identifies the parotid gland as the most common anatomical site for salivary gland tumors. This gland accounts for the largest share of all salivary gland tumor occurrences.
Summary of Correct Statements
Evaluating each statement:
- Statement 1: Incorrect (Parotid tumors are mostly benign)
- Statement 2: Correct (Sublingual tumors have high malignancy rate)
- Statement 3: Correct (Submandibular tumors have a significant benign percentage)
- Statement 4: Correct (Parotid is the most common site)
The correct statements are 2, 3, and 4, corresponding to Option B.
