For transgender males and non-binary people, a mastectomy, sometimes known as top surgery, is a serious surgical procedure used to remove breast tissue and give the chest a more masculine shape. In order to treat gender dysphoria and harmonise a person's physical appearance with their gender identity, it is a crucial part of gender-affirming care. There are several distinct forms of mastectomy, including complete (simple), modified radical, radical, skin-sparing, and nipple-sparing mastectomy.

• For screening, complete assessment to evaluate the individual's readiness and suitability for mastectomy are performed. 

• The size and location of the incision depend on the type of mastectomy being performed. For different types of mastectomy, there are different criteria that needs to be fulfilled. 

• The incision site is typically covered with sterile dressings and bandages to protect the wound and promote healing.

• Ongoing support and follow-up care to ensure a healthy recovery and address any post-surgery concerns.
