Which of the following is a common symptom of cancer treatment?

Fatigue is a well-documented and common symptom experienced by individuals undergoing cancer treatment. This can occur due to a combination of factors including the physical toll that the disease and its treatment (such as chemotherapy, radiation, or surgery) take on the body, as well as emotional stress and the body's effort to heal and fight the disease. Fatigue may manifest as a persistent sense of tiredness or lack of energy that does not significantly improve with rest.

In contrast, increased energy levels, weight gain, and improved cognitive function are not typical symptoms associated with cancer treatment. In fact, many patients experience decreased energy levels and cognitive challenges, commonly referred to as "chemo fog" or cognitive dysfunction, as a side effect of their treatment. Understanding these nuances can help patient navigators provide better support and resources tailored to the needs of patients undergoing treatment.
