A recently published survey of women from California and Georgia who were diagnosed with early-stage breast cancer found that nearly half of them had at least one severe or very severe side effect. In all, 93% of the women said they had at least one of seven side effects noted on the questionnaire and 45% of the women said they had at least one severe or very severe side effect, including pain, skin irritation, and constipation.
