Are these the symptoms of breast cancer?

symptoms are similar to me.i do mammograms of breast cancer patients everyday. and i see them have these symptoms varying upon eachother. breast does enlarge and gets hardened and skin becomes flaky. nipple invertion and discharge is also common. pain is not a common factor.but if u have mastalgia u will be having severe pain together with the lumps. i think you should take it seriously and see a doctor, do not panic cause it could be anything but cancer. usually cancer is found in people above the age of 45.but not so rarely in younger age group as well. breast cancer runs in the family sometimes.you could find out about these information and see a dr soon as possible
