Which of the following is NOT a side effect of chemotherapy?

Cyanotic lymph nodes are not typically recognized as a side effect of chemotherapy. Chemotherapy primarily targets rapidly dividing cells, which can affect not only cancer cells but also normal cells in the body leading to common side effects such as nausea and vomiting, hair loss, and fatigue.

Nausea and vomiting occur due to the impact of chemotherapy on the gastrointestinal tract and the brain’s vomiting center. Hair loss results from the damage to hair follicles as chemotherapy drugs attack rapidly dividing cells. Fatigue is a frequent side effect, stemming from the body’s response to both the drugs and the cancer itself.

In contrast, cyanosis refers to a bluish discoloration of the skin or mucous membranes due to insufficient oxygenated blood, which is not a typical reaction to chemotherapy. While lymph node abnormalities can occur in various medical conditions, including those treated with chemotherapy, the specific presentation of cyanotic lymph nodes is not a recognized or expected side effect of the treatment itself.
