prevent breast cancer

I have suffered breast cancer at my youth, 20-year-old. At first I had severe pains in one of my breasts, and there was also a some-what large and hard lump in the same one. However my other breast seemed perfectly normal. I don't know if this had anything to even do with it.I went to the doctor, I would like to know what this meaned, and if it meaned that i might have breast cancer. Was it even possible to have breast cancer at age 20?
Fortunately, I went to the doctor and get an accurate diagnosis and correct treatment. I am fine now.I have paid 200% attention to breast health and how to prevent breast cancer.

Dear victorialin, Yes it is possible for someone to be diagnosed with breast cancer at age 20, although this is not common.  Breast pain is not usually a symptom of breast cancer, however a large hard lump is something that should be checked out.  You did the right thing by having your symptoms evaluated by your doctor, so you could get the appropriate advise and treatment.
