Submandibular mass?


Hello, doctor: Around April of this year, I noticed a swelling below my right ear, approximately 1 to 1.5 centimeters in size.
It does not hurt when pressed and is soft and movable.
So far, it has neither increased nor decreased in size.
Could you please explain what this might be? Do I need to go to a major hospital for a detailed examination?

When it comes to submandibular lumps, there are several factors to consider in determining whether medical attention is necessary. The lump you described, located beneath the right ear and measuring approximately 1 to 1.5 cm, is soft, movable, and has not changed in size over time. These characteristics can provide some clues about the nature of the lump.

First, it's important to understand that lumps in the submandibular area can arise from various causes, including lymph nodes, salivary glands, cysts, or even tumors. Lymph nodes can become enlarged due to infections, inflammation, or malignancies. Salivary gland issues, such as sialadenitis or salivary stones, can also lead to swelling in this area. Cysts, such as a branchial cleft cyst or a dermoid cyst, are common in younger individuals and can present as soft, movable lumps.

Given that the lump is soft and movable, it may suggest that it is not a solid tumor, which is often firmer and less mobile. However, the fact that it has persisted for several months without change does warrant further evaluation. While many benign conditions can present as submandibular lumps, it is essential to rule out any serious underlying issues, especially if there are any accompanying symptoms such as pain, fever, or changes in swallowing or speaking.

Here are some guidelines on when to seek medical attention for a submandibular lump:
1. Duration: If the lump has been present for more than two weeks without improvement, it is advisable to consult a healthcare professional.

2. Size Changes: Any increase in size or the appearance of new lumps should prompt a medical evaluation.

3. Associated Symptoms: If you experience pain, fever, difficulty swallowing, or any other concerning symptoms, you should seek medical attention promptly.

4. Personal Medical History: If you have a history of cancer or other significant medical conditions, it is prudent to have any new lumps evaluated.

5. Age Considerations: In younger individuals, certain types of cysts are more common, but in adults, a lump that persists should be evaluated to rule out malignancy.

In your case, since the lump has not changed in size and is not painful, it may be benign, but it is still important to have it evaluated by a healthcare professional. A thorough examination, possibly including imaging studies such as an ultrasound or CT scan, may be necessary to determine the nature of the lump. In some cases, a biopsy may be required to obtain a definitive diagnosis.

In conclusion, while the characteristics of your lump may suggest it is benign, it is always best to err on the side of caution. Consulting with a healthcare provider will help ensure that any potential issues are addressed early on, providing peace of mind and appropriate management if necessary.
