Hi, I am 22 years of age and am now four months pregnant with my second bay. My first one is 3 years 8 month. I stop breast feeding my first child when she is 1 year and 3 months. Some months after that i feel slight pain in my breast (only when I touch it or when I bump into something) and moving lumps. After I did some test, some doctors said that i have breast fibrosis. So I just wanna know if this disease is harmful during my pregnancy or when I breast feed. Some weeks back I also feel slight pain in my underarms on both side. There is no discharge or anything like that. Is this dangerous?
