Is Efudex used for skin cancer?

Is Efudex (fluorouracil) used to treat skin cancer?

Efudex is a brand name for 5-fluorouracil (5-FU) topical cream. It is used on the skin to treat certain precancerous lesions and some skin cancers, depending on the specific condition and how it is prescribed.

It is commonly used for actinic keratosis (sun-damaged, precancerous skin lesions). For some patients, clinicians also use topical 5-FU in regimens for superficial skin cancers where a non-surgical topical approach is appropriate.

What skin conditions does Efudex typically treat?

Efudex is most often associated with:
- Actinic keratosis (a precancerous lesion linked to sun exposure)
- Some superficial skin cancers (topical therapy may be used when lesions are limited to the surface)

How do doctors decide whether Efudex is appropriate?

Use depends on factors like:
- The lesion type (precancer vs. superficial cancer)
- Lesion size and location
- Whether the area is suitable for a topical course instead of surgery or other treatments

Is Efudex the same as chemotherapy for internal cancer?

No. Efudex is topical 5-FU and is used for localized skin disease (precancers and selected superficial cancers). That’s different from chemotherapy given by mouth or injection for internal cancers.
