  1. That is very true. If a lump is found earlier it is normally much more treatable. When people wait to long the cancer just gets to progress and grow more.

  2. Early identification is key. Performing self breast exams monthly, having a mammogram done, and going to the doctors when finding a lump could help prevent the tumor getting bigger. The outcome is always better when a person finds the tumor when it is smaller.
