FAQ
Frequently Asked Questions
It is most commonly used to treat cancers of the colon, rectum, breast, and stomach, and topically for certain pre-cancerous and cancerous skin conditions like actinic keratosis and superficial basal cell carcinoma.
It works by being incorporated into RNA and inhibiting an enzyme called thymidylate synthase, which is essential for DNA synthesis. This disrupts the growth and division of rapidly proliferating cells, such as cancer cells.
Common side effects include myelosuppression (low blood counts), mucositis (sores in the mouth and digestive tract), diarrhea, nausea, loss of appetite, and skin changes like hand-foot syndrome.
Topical fluorouracil cream is prescribed for home application. Intravenous or injectable fluorouracil is administered in a hospital or clinic setting under medical supervision due to its potency and potential side effects.

Mnemonic
Think: 'FLUORO' (like fluorine/fluoride) + 'URACIL' (a RNA base). A uracil base that has been fluorinated to become a dangerous impostor for cancer cells.
Conceptual Metaphor
A 'MOLECULAR SPY' or 'TOXIC IMPOSTOR'—a substance that looks like a normal building block (uracil) to a cell but is fatally flawed, sabotaging the cell's replication machinery from within.
