<<Disclaimer: Verify this information before applying it to your situation.>> My sister has just learned that she has inflammatory breast cancer, a rare type of breast cancer that arises in the lymph system in the breast. (This accounts for only 1 to 4 percent of breast cancers.) Since this involves the lymph system, is this a type of lymphoma? Might this have any connection with untreated celiac disease? Any info would be appreciated. Thank you--Trisha Stevenson
