What are the alternatives to topical 5-fluorouracil?

Topical 5-fluorouracil is prescribed for selected sun-damaged or abnormal surface cells. Actinic keratosis may appear as a rough, scaly patch, while actinic cheilitis affects the lip. Bowen's disease is an early form of squamous cell skin cancer and needs a treatment plan based on examination.

Photodynamic therapy uses a light-activated medicine and a specific light source to treat selected abnormal cells. Other options may include a procedure that removes or destroys an individual lesion. The right choice depends on thickness, number, site, recurrence, and whether a sample is needed.

Do not substitute another cream or stop a prescribed course without confirming the diagnosis and plan. Ask whether the area needs a biopsy, whether treatment should cover visible and microscopic change, and how the response will be checked.

Protect treated skin from sunlight as directed and follow wound-care instructions. Keep a record of the treatment dates and any reaction, especially if redness, crusting, or soreness is difficult to manage.

Arrange prompt review for a lesion that grows, becomes tender, bleeds, ulcerates, or fails to heal. During treatment, seek advice for severe pain, spreading infection signs, marked swelling, or a reaction that prevents eating, drinking, or normal daily activity.

What diagnosis are we treating, and does it need a biopsy? Is photodynamic therapy suitable for this site? What reaction should I expect? How will you confirm clearance and protect the area from further sun damage?
