I get breast pain the 2 weeks before my period, worse pain in the right one, plus it itches sometimes. does that mean breast cancer?

Not likely: Painful & sometimes swollen or lumpy breasts, worse around the menstrual cycle, is most often a benign fibrocystic condition. However, a firm breast lump that persists would be concerning. See a doctor for a breast examination.

No: These are changes and symptoms that occur normally in reaction to hormonal changes. The breasts can also feel lumpier too. If you have lumps that do not feel normal to you, then i recommend you get evaluated by your doctor.

No: This is most likely physiologic. Your breasts are responding to the hormones in your body. You should discuss your concerns with your friendly primary care physician.

No cancer: The menstrual period represents the effect of hormone activity and changes on the uterus. Thus two weeks before period when estrogen secretion is highest and before progesterone appears the hormone has effects on many tissues including breast. At that point maximum secretion of fluid and dilatation of milk ducts occur to cause your symptoms. No Ca involved.
