I've been extremely worried as a couple days ago I felt a lump in my right breast however it comes and goes. I've been having sharp pain in that spot for over 2 weeks which is getting progressively worse. The pain gets a lot worse when I touch it. 2 days ago I woke up and my whole right breast was was swollen and almost doubled in size. This went down after about 2 hours. I heard breast pain isn't usually a sign of breast cancer. Any suggestions?
