		<description><![CDATA[Question:  What is the difference between invasive lobular and ductal carcinoma? My first biopsy I had at my ultrasound said &#8220;invasive lobular carcinoma grade 2/3&#8243; and my surgery biopsy said &#8220;invasive ductal carcinoma grade 2/3&#8243;. Does this make any difference?
 Answer: Not really, because a core biopsy only samples part of the tumor.  [...]]]></description>
