Enucleation is a surgical procedure typically performed for which type of cancer?

Breast cancer
Ocular melanoma
Lung cancer
Skin cancer

The correct answer is: Ocular melanoma

Enucleation is a surgical procedure that involves the removal of an entire organ or tumor, and it is most commonly associated with the treatment of ocular melanoma, which is a type of cancer that occurs in the uveal tract of the eye. This procedure is necessary in cases where the tumor is large or has invaded surrounding tissues and preservation of the eye is not feasible. By performing an enucleation, the surgeon aims to remove the cancerous tissue completely, thereby reducing the risk of metastasis and addressing related complications. In contrast, while breast cancer, lung cancer, and skin cancer can require various surgical interventions, enucleation is not a standard procedure for these types of cancer. Breast cancer may involve lumpectomy or mastectomy, lung cancer can be treated with lobectomy or pneumonectomy, and skin cancer usually requires excision of the tumor. Each of these cancers has specific surgical techniques tailored to them, but none typically necessitate the enucleation approach used in ocular melanoma cases.
