I'm confused plaese help.

My fiancy just discovered painful lump in her left breast and at about two weeks now she has not seen her period and she told me that she has not seen any sign that she's pregnant. Though I took her to doctor but after check up the doctor told us that there's no problem. Could this be cancer?

Hi,
Painful breast lumps are rarely associated with breast cancer.They are most commonly due to benign conditions such as a cysts or fibroadenomas.These lumps would usually vary in size in accordance with her menstrual cycle, but it is also not unusual for these lumps to remain or enlarge.
If the lump persists,enlarges or becomes too painful,she should ask her doctor to further investigate it by having a mammogram or an Ultrasound .
All the best to both of you.
