Length of overnight fasting linked to increased risk of breast cancer recurrence

Researchers suggest increasing duration of nightly fasting may improve prognosis in patients with breast cancer according to a new study:

Researchers also reported that fasting fewer hours per night was associated with significantly less sleep and higher levels of glycated hemoglobin (HbA1c), which is a measure of average blood sugar levels over a period of months. These findings are relevant to cancer prevention and control efforts because elevated HbA1c and poor sleeping habits have been linked to an increased risk of breast cancer.
