Breast cancer treatment can cause short-term and long-term side effects that vary substantially and depend on the specific therapy used. Common side effects of chemotherapy include stomach complaints like appetite loss, diarrhea, constipation, and nausea/vomiting; fatigue, hair loss, edema, brittle skin and nails, easy bruising/bleeding, anemia, mouth sores, and changes to libido and fertility.[1] A healthcare provider will help individuals manage side effects from breast cancer therapy.
