Which symptom is unlikely to be associated with chemotherapy?

Chemotherapy is known for a variety of side effects due to its impact on rapidly dividing cells in the body. Symptoms commonly associated with chemotherapy include nausea, hair loss, and insomnia. Nausea and vomiting are well-recognized side effects, often resulting from the effect of chemotherapy on the gastrointestinal tract. Hair loss occurs because chemotherapy targets all rapidly dividing cells, which includes hair follicles. Insomnia may arise from physical discomfort, anxiety about treatment, or other psychological factors related to cancer and its treatment.

In contrast, increased appetite is generally not a symptom associated with chemotherapy. In fact, many patients experience decreased appetite due to nausea, changes in taste perception, or psychosocial factors such as depression or anxiety. Therefore, identifying increased appetite as a companion symptom to chemotherapy treatment is unlikely, making it the least accurate choice when considering chemotherapy's side effects.
