**Core Concept**
Fordyce spots are small, yellowish or white papules found on the lips, oral mucosa, or genitalia. They represent ectopic sebaceous glands, which are normally found in the skin but have aberrantly migrated to these locations.

**Why the Correct Answer is Right**
Fordyce spots are benign and asymptomatic, often discovered incidentally during routine physical examination. They are the result of the ectopic presence of sebaceous glands, which produce sebum. The presence of Fordyce spots is thought to be due to the incomplete development of the salivary glands during embryogenesis.

**Why Each Wrong Option is Incorrect**
**Option A:** Fordyce spots are not usually associated with an increased risk of oral cancer. This is incorrect because Fordyce spots are actually considered a benign condition and are not a risk factor for oral cancer.

**Option B:** Fordyce spots can be associated with certain genetic disorders. This is incorrect because while some genetic disorders may be associated with ectopic sebaceous glands, Fordyce spots themselves are not typically a diagnostic feature of any specific genetic condition.

**Option C:** Fordyce spots are a type of precancerous lesion. This is incorrect because Fordyce spots are benign and are not considered precancerous.

**Clinical Pearl / High-Yield Fact**
Fordyce spots can be distinguished from other oral lesions by their characteristic yellowish or white color and their small size.

**Correct Answer:** C. Fordyce spots are a type of precancerous lesion.
