Best oncologist in Doha & phone number please

I need a good doctor - oncologist - for breast cancer here in doha and the phone number.

i already researched here in qatarliving and some helpful sites but no phone numbers are noted down.

i also tried hamad hospital but got nowhere. unfortunately its either the communication barrier or perhaps unwillingness to listen to my query that got me fed up calling their different lines countless times (even asking the appointment/scheduler section is a pain).
