Mathematical modeling of temperature variation in breast tissue with and without tumor/cyst during menstrual cycle

The thermoregulation of human female body is influenced by hormonal and physiological changes in the body during the menstrual cycle.  The fluctuation of estrogen and progesterone hormones, release in the follicular phase and the luteal phase of menstrual cycle, respectively play an important role in the growth of breast ducts and lobules (milk glands).  The imbalance of these hormones causes breast tumors/cysts.  The body core temperature, blood perfusion and metabolism rate are higher in the luteal phase than the follicular phase of menstrual cycle.  In the present work, a tumor/cyst is a
