Can the use of sunscreen daily help to prevent melanoma?

Question

Hi doctor,

In our community, we have had two cases of melanoma, and with summer approaching, there has been a lot of talk about high radiation levels and the importance of using sunscreen. People are even considering organizing a community awareness event. I know melanoma is serious if not caught early. From an oncology perspective, how important is regular sunscreen use in preventing melanoma? Are there other effective measures we should consider for protection against high UV radiation during the summer? Any advice on how to effectively raise awareness and promote skin health in our community would be greatly appreciated.

Thank you.

Hi,

Welcome to icliniq.com.

I read your query and understand your concern.

From an oncology perspective, regular sunscreen use is considered an essential part of preventing melanoma (a kind of skin cancer that starts in the melanocytes) and other types of skin cancer. While sunscreen alone cannot completely eliminate the risk of melanoma, it plays a crucial role in reducing exposure to harmful UV (ultraviolet) radiation, which is a major risk factor for developing skin cancer.

UV radiation from the sun damages the DNA ( deoxyribonucleic acid) in the skin cells, which can lead to the development of melanoma and other skin cancers over time. Sunscreen helps to protect the skin by absorbing or reflecting UV radiation, thus reducing the amount of damage inflicted on skin cells.

Consistent and proper use of sunscreen, along with other sun protection measures such as seeking shade, wearing protective clothing, and avoiding peak sun hours, can significantly lower the risk of melanoma. It is important to choose a broad-spectrum sunscreen with a high SPF (sun protection factor) rating and to apply it generously and regularly, especially when spending time outdoors.

Oncologists often emphasize the importance of sun protection practices, including regular sunscreen use, as part of comprehensive skin cancer prevention strategies for their patients. In addition to regular sunscreen use, there are several other effective measures to consider for protection against high UV radiation during the summer:

1. Seek shade: Whenever possible, seek shade, especially during peak sun hours, between 10 a.m. and 4 p.m. This reduces direct exposure to UV radiation.

2. Wear protective clothing: Wear lightweight, long-sleeved shirts, pants, and wide-brimmed hats to cover exposed skin. Darker colors and tightly woven fabrics offer better protection.

3. Use sunglasses: Wear sunglasses that block both UVA (ultraviolet A) and UVB (ultraviolet B) rays to protect your eyes and the sensitive skin around them.

4. Avoid tanning beds: Tanning beds emit harmful UV radiation and increase the risk of skin cancer, including melanoma. It is best to avoid them altogether.

5. Stay hydrated: Drink plenty of water to keep your skin hydrated and healthy, especially when spending time outdoors in the sun.

6. Plan outdoor activities wisely: If possible, schedule outdoor activities in the early morning or late afternoon to avoid the strongest sun exposure.

7. Check the UV index: Pay attention to the UV index, which forecasts the strength of UV radiation in your area. Plan outdoor activities accordingly, and take extra precautions when the UV index is high.

8. Apply lip balm with SPF: Do not forget to protect your lips by using a lip balm with SPF protection.

By combining these measures with regular sunscreen use, you can effectively reduce your exposure to harmful UV radiation and lower your risk of developing skin cancer, including melanoma.

Breslow classification of melanoma:

Stage I - Thickness of 0.75 mm or less.

Stage II - Thickness of 0.76 -1.5 mm.

Stage III - Thickness of 1.51 - 4 mm.

Stage IV - Thickness greater than 4 mm.

I hope that you get your answer.

Please let me know if you want some help.

Thank you.
