Side effects during breast cancer treatment can include changes in taste, smell and appetite. Known as taste alterations, these symptoms cause an aversion to food, which can result in weight loss, poor nutrition and an increased risk of hospitalization.
A loss of interest in food and mealtimes can also negatively affect quality of life by limiting social interaction during mealtimes. Small changes in ingredient choices and food preparation can help improve a patient’s relationship with food during treatment.
Changes in smell, taste and appetite during treatment
Chemotherapy, radiation therapy and hormone therapy can affect smell, taste and appetite. These taste alterations are usually temporary and should disappear in the weeks following the end of treatment.
