Risk factors for inflammatory and non-inflammatory breast cancer in North Africa.

ABSTRACT:

Purpose

Studies of the etiology of inflammatory breast cancer (IBC), a rare but aggressive breast cancer, have been hampered by limited risk factor information. We extend previous studies by evaluating a broader range of risk factors.
