Are very painful breast lumps associated with cancer?

They can be. A common misconception is that if a woman has a tender, painful lump in their breast, it is unlikely to be cancer. While it is true that many women with breast cancer do not have breast pain, the presence of pain does not exclude cancer as the cause. Bottom line: a new lump in the breast, painful or not, warrants medical evaluation.

Need for examination. It is not feasible to provide a meaningful answer without examining the lump and it will probably require a mammogram and/or biopsy. Most lumps are not cancer. See this site for more info. http://www.mayoclinic.com/health/breast-lumps/my00165. Read more...
