I have a lump on my breast getting bigger my doctor said its fat tissue not happy with his answer could it be cancer i'm scared it hurts when i push o?

Get 2nd opinion : I would recommend getting a second opinion. Have you had a mammogram or ultrasound?

Breast lump: Breast cancer doesn't usually hurt per se, at least not initially when localized. Breast cysts can change in size & can be painful if large enough. Depending upon australian guidelines, you could consider asking for a mammogram +/- ultrasound depending upon findings followed by aspiration. Check out http://www.Mayoclinic.Com/health/breast-cysts/ds01071 for more info.

Get a mammogram: Ask your doctor to write a prescription or referral for a diagnostic (as opposed to a screening) mammogram and diagnostic ultrasound. Fatty tissue shouldn't cause discomfort. If your doctor won't order these tests, see another doctor right away. I never take any breast abnormality lightly.
