Final answer:
Chemotherapy induced oral mucositis typically develops between 4 to 7 days after standard chemotherapy treatment due to damage to rapidly dividing cells in mouth lining.
Step-by-step explanation:
Chemotherapy induced oral mucositis typically develops 4 to 7 days following standard-dose chemotherapy. One of the common adverse effects of chemotherapy is that it can damage the rapidly dividing cells of the body's normal tissues such as the lining of the mouth, which leads to conditions like oral mucositis. This condition can be painful and can cause difficulties in eating and speaking, impacting the patient's quality of life significantly.
