Explanation:

Cancer can disrupt the body's normal healing processes. Sores that do not heal can be a sign as cancer cells may interfere with the body's ability to repair damaged tissues. Resistance to insulin is more related to diabetes. Onset of a gluten allergy is an autoimmune - related issue not typically a direct cancer symptom. Sensitivity to alcohol can have various causes like liver problems (not specific to cancer).
