Possible side effects after mastectomy surgery are:

After mastectomy surgery, various side effects can manifest as a result of the surgical procedure. Numbness along the incision site is common due to the disruption of nerves during the surgery. This can lead to loss of sensation in the affected areas, which may alleviate over time but can be a concerning side effect immediately post-surgery.

Formation of scar tissue is another potential side effect, as surgical incisions often heal with scar formation. This can impact the surrounding tissues and may be noticeable both externally and internally. The process of healing naturally involves collagen formation and can lead to changes in tissue texture and flexibility.

Increased risk of infection is also a critical concern following any surgical procedure, including mastectomy. The surgical site is a potential entry point for bacteria, and if proper post-operative care is not followed, infections can occur, complicating recovery.

Given that all these effects can be legitimate concerns for patients recovering from mastectomy surgery, the correct answer encompasses all listed possibilities, highlighting the complex nature of recovery from this type of surgery. This comprehensive understanding of potential side effects is essential for patients to discuss with their healthcare providers and to manage their post-operative care effectively.
