Summary
"This trial aims to compare two treatments, cryotherapy and 5-Fluorouracil (5-FU), for actinic keratosis, a skin condition caused by sun exposure.
Who is the study for?
This trial is for individuals with actinic keratosis, a skin condition from long-term sun exposure. Participants will have their demographics and medical history recorded and must be willing to receive both cryotherapy and 5-Fluorouracil on different body areas, complete weekly surveys, and return for follow-ups.
What is being tested?
The trial compares the effectiveness of cryotherapy (freezing abnormal cells) versus 5-Fluorouracil cream (interfering with cell growth) in treating actinic keratosis. It assesses which reduces lesions better and evaluates side effects, patient satisfaction, cosmetic outcomes, and quality of life.
What are the potential side effects?
Cryotherapy may cause pain at the treatment site or changes in skin pigmentation. The topical cream 5-Fluorouracil can result in redness, irritation, burning sensation at the application area or increased sensitivity to sunlight.
