Wide excision意思

"Wide excision" is a surgical term that refers to the removal of a tissue or lesion, along with a significant margin of surrounding healthy tissue. The purpose of a wide excision is to ensure that all cancerous or potentially cancerous cells are removed, minimizing the risk of the disease recurring.

In the context of cancer treatment, wide excision is often used for the removal of tumors or lesions that are close to critical structures, such as nerves or blood vessels, where a narrower margin of excision might leave cancer cells behind. The width of the excision margin can vary depending on the type of cancer, the grade of the tumor, and the surgeon's preference.

For example, in the case of skin cancer, a wide excision might involve removing a margin of healthy skin around the tumor that is at least 1 cm wide. In some cases, even wider margins may be necessary, especially if the tumor is large or has certain characteristics that make it more likely to spread.

Wide excision is typically performed under general anesthesia and may be followed by reconstructive surgery to repair the area where the tissue was removed. The goal of wide excision is to achieve a cure or to significantly reduce the risk of the cancer coming back.
