What is a key preventative measure for skin cancer after a malignant melanoma is removed?

Wearing sunscreen with a high SPF greater than 30 is a crucial preventative measure after the removal of a malignant melanoma. This is because UV radiation is a significant risk factor for skin cancer, including melanoma. By using sunscreen, individuals can protect their skin from harmful rays that can contribute to the development of new skin cancers. It is also essential to check the skin for changes on a regular basis, in this case, weekly, as early detection of any new moles or changes in existing moles can significantly improve outcomes.

Regular monitoring can help in identifying any suspicious changes early on, which is vital in the context of a history of melanoma, where there is an increased risk of developing new skin cancers. The combination of proactive sun protection and vigilant self-examination makes this option a comprehensive approach to skin cancer prevention post-treatment.
