Dear doctor, my wife saying her left size breast is paining. We are having two year old daughter. Her periods is expected to come by aug 1st 2020. She is also having her irregular periods due to pcos. Any relation is there between periods arriving date and breast pain. Or this may be due to any breast issue we can't get the real reason. We are really fear whether this may be starting of breast cancer. How to examine the same in home and how to escape from that cancer. Kindly give some tips and foods. Due to covid we are afraid to consult doctor directly in hospital. Kindly suggest asap pls.
