Excision refers to the process of removing or cutting out a specific part or portion, typically through surgical means. It involves the deliberate removal of tissue, organs, lesions, or tumors from the body. Excisions are commonly performed to treat various medical conditions or diseases, ranging from skin cancer to appendix removal.
In surgical procedures, excision may involve making an incision or using specialized tools to carefully remove the targeted area or structure. Surgeons may choose to perform excisions for diagnostic purposes, as a means of obtaining a tissue sample for examination and analysis. This helps to determine the presence of diseases or to assess the extent of damage or malignancy.
Excision is also widely used in the field of dermatology. Dermatologists often perform skin excisions to remove abnormal growths such as moles, cysts, or tumors, or to extract suspicious lesions for further examination. Additionally, excision may be used as a treatment option for ingrown toenails, cancers, or other skin disorders.
In the context of DNA research, excision refers to the removal of certain segments or fragments of DNA from the double helix structure. This process can be employed to study specific genes or to remove unwanted sequences from the genetic material.
