What is the pathophysiology of cancer post-surgery?

• A. Tissue trauma, reduced mobility, pain, and functional deficits due to surgical resection.
• B. Enhanced mobility and no pain.
• C. Cancer cleared with no residual effect.
• D. Increased tissue regeneration without deficits.

Answer: (A)

After cancer surgery, the body responds to tissue injury from the incision and removal of tissue. This trauma initiates the wound-healing cascade: inflammatory mediators are released, vessels become more permeable, and swelling and tenderness develop. Pain signals are activated, and muscle guarding and discomfort often limit movement. Reduced mobility is common as tissues heal and scar forms, which can also lead to decreased strength and range of motion. If nerves or lymphatics are affected during surgery, additional deficits such as neuropathic pain or swelling can occur. Systemic stress from the operation can cause fatigue and temporary metabolic changes, further contributing to functional limitations. This combination of tissue trauma, inflammation, pain, and resulting functional deficits captures the typical post-surgical pathophysiology in cancer care, making the described option the best fit. The other choices either imply no pain or no functional impact, or claim the cancer is completely cleared with no residual effect, which do not reflect the actual post-operative physiological response.
