I'm 40 years old and had my 1st Mammogram in April 2017. They said they found dense tissue and wanted to recheck in 6 months. I went for the 2nd Mammogram January 10th this year. This time both if breasts we're swollen and hurt pretty bad. However, it's been almost a week and my right breast is still swollen by at least a whole cup  it's normal size and I have a stinging pain the nipple area. How could this ever be healthy for a woman
