Keloid scar patches

Hello Dr.
Lee: I have a keloid on my chest that has been present for 7 years (measuring 3 cm by 2 cm).
I would like to ask if it is safe for me to use silicone gel sheets on this keloid long-term? (I don't experience much allergic reaction after applying them myself.) I currently apply them daily and feel that the itching has decreased.
If I continue to use them for over 10 years, will this increase the risk of developing scar cancer? I appreciate your clarification on these two questions.
Thank you, and I wish you all the best.

More Info

When it comes to the long-term use of silicone sheets for hypertrophic scars, there are several important factors to consider regarding safety and efficacy. Hypertrophic scars, which are raised scars that can develop after injury or surgery, can be effectively managed with silicone sheets. These sheets work by providing a moist environment, which can help flatten and soften the scar over time.

Efficacy of Silicone Sheets
Research has shown that silicone sheets can be effective in reducing the appearance of hypertrophic scars. They help to hydrate the scar tissue, which can lead to improved texture and color. The pressure and occlusion provided by the silicone sheets can also inhibit the production of collagen, which is responsible for the raised nature of hypertrophic scars. Many patients report a reduction in itching and discomfort associated with these scars when using silicone sheets.

Long-term Use
Regarding the long-term use of silicone sheets, it is generally considered safe. Many dermatologists recommend using silicone sheets for several months to a year, depending on the severity of the scar. Some patients may choose to use them for longer periods, especially if they find them beneficial. In your case, since you have been using the silicone sheets for an extended period (daily for several years) and have not experienced any adverse reactions, it seems that your skin tolerates the treatment well.

Concerns About Cancer Risk
Your concern about the potential increase in cancer risk from long-term use of silicone sheets is understandable. However, current medical literature does not support the idea that silicone sheets can cause or increase the risk of scar-related cancers, including scar carcinoma. Silicone is a biocompatible material, meaning it is generally well-accepted by the body and does not induce harmful reactions. The primary concern with long-term use would be skin irritation or allergic reactions, which you have not experienced.

Recommendations
1. Continue Monitoring: Since you have been using the silicone sheets without issues, you can continue to do so. However, it is essential to monitor your skin for any changes, such as increased irritation or new symptoms.

2. Consult Your Dermatologist: Regular follow-ups with your dermatologist can help assess the effectiveness of the treatment and make any necessary adjustments. They can also provide guidance on the duration of use based on your specific situation.

3. Consider Other Treatments: If you notice that the silicone sheets are no longer effective or if you wish to explore additional options, your dermatologist may suggest other treatments, such as corticosteroid injections, laser therapy, or other topical treatments.

4. Hydration and Skin Care: Maintaining proper hydration of the scar area and using gentle skin care products can also support the healing process.

In conclusion, long-term use of silicone sheets for hypertrophic scars is generally safe and can be effective. Your current experience of reduced itching and discomfort is a positive sign. Always keep an open line of communication with your healthcare provider to ensure the best outcomes for your scar management.
