Final answer:
Unsound tissue in the area of a malignant tumor, like melanoma, needs to be surgically excised. This is to remove the cancerous cells, which may include the tumor and surrounding tissues.
Step-by-step explanation:
Unsound tissue in the area of a malignant tumor, such as a melanoma, should generally be excised. This refers to the surgical removal of the cancerous lesion. Melanoma is a type of skin cancer that originates in the melanocytes in the epidermis and can be highly metastatic. Surgery is often the primary treatment for localized, solid cancers like melanoma, and it aims to remove the entire tumor along with some of the surrounding tissue, which may include local lymph nodes, to ensure that all the malignant cells are removed. This can potentially cure the cancer if it has not spread, and even if it has, it can alleviate symptoms and prolong survival.
Unsound tissue in the area of a malignant tumor should be excised. This means that the unhealthy tissue should be surgically removed to prevent the spread of cancer cells. Surgical excision is a common treatment for many types of cancer, including melanoma, which is a highly metastatic and dangerous form of skin cancer.
