Why the Second Treatment May Feel Different
The second chemotherapy treatment can feel different for several reasons. You’ve already had some side effects from the first treatment, so you know what to expect. Your body might not have fully recovered from the first treatment, making side effects worse. Also, your mental and emotional state can change how you feel about the treatment.
Talking to your healthcare team about any concerns or changes is key. They can help manage side effects and support you through this tough time.
