Breast pain, armpit, arm pain

[sparkler11]

I found a lump in my left breast, have had a diagnostic mammogram and an ultra sound resulting that everything is fine.
As a precaution, my Dr. wants me to be examined by a general surgeon, which is scheduled.

I have slight breast pain, an ache in that particular area extending to my armpit and into my arm.
Sometimes my arm aches so greatly, I use a heating pad.
Should I be concerned?
Is any of this related and if so, what might it be called?
Is this normal?



This discussion is related to Swollen left breast, pain in left arm, lump under arm pit.

Are lobular neoplasms or LCIS common?
Are they cancerous?
In other words, how concerned should I be?

Sincerest thanks for this information.
I will most definitely discuss this with my surgeon!
It is a relief to have some kind of explanation!

Hi there.

The negative mammogram and ultrasound are all comforting and what you are experiencing may be due to hormonal changes in the breast, or strained muscles and connective tissues in that area.  However, there is a subtype of breast lumps that do not show up on ultrasound or mammogram.  These are the lobular neoplasms or LCIS.  This can be manifested on tests like breast MRI.

The surgeon consult should be fruitful, and I believe you should discuss this option of MRI when you get to meet him.

Regards.
