Hi, I have a small white bump on the hard palate of my mouth - slightly right of center. It is about 2mm, slightly raised, well defined, symmetrical but not exactly circular. It has been there now for over 9 months. My doctor (General Practitioner) had said it was not cancer, but a cyst. I think it began as a result of trauma (hard food), but I am not sure. Should I be worried and get a second opinion. See attached photograph

Thanks for the query.

Your general practitioner is right; it is a mucous retention cyst, which is benign and not harmful.

To explain to you in detail, salivary glands in the oral cavity are categorized into major and minor salivary glands. Major salivary glands include parotid, sub-mandibular and sublingual salivary glands. Apart from this, there are numerous minor salivary glands which are situated all over the buccal mucosa, tongue, palate, pharynx, etc.

Sometimes, due to trauma or inflammation of the mucosa there is blockage of the ducts supplying the saliva. Due to the blockage of the duct, there is retention of the salivary secretions in the minor salivary glands leading to the formation of a cyst. Cyst is a sac like structure with collection of saliva. It is usually harmless and does not turn into cancer.

If the swelling is hurting you while taking food or on touching, it can be removed surgically or else, it can be left alone.

Hope I have answered your query; I will be available for the follow-up queries.

I will keep monitoring this cyst. What will be the signs that I should look out for that may indicate that it is more than a cyst and needs further attention.

Welcome back.

I can assure you that this cyst is harmless. If you feel, it is progressively increasing in the size or becoming painful, you need to consult your ENT specialist for a complete examination.

Wish you good health.
