lump on top of shoulder

My mother(78 years old )  has stage 4 colon cancer. ( below is the finds after surgery ) 

Her treatment plan is Chemo (oxaliplatin) by port once every two weeks and xeloda for two weeks. She has been doing this November. 

Her first PET scan  ( Sept. 2016) showed lymph nodes that was involved also with the addition of the para-aortic being involved on the opposite of the colon cancer find. 

The second Pet Scan ( early Feb 2017) showed no new places and a big decrease in size of all Lymph nodes involved. 

Fast forward to last week. We have a lump on top of shoulder. Its about a inch from the base of her neck. Lump is soft and zero pain or tenderness .

We are seeing her Dr. this week. Just wondering if anyone had a lump show up out of the blue like this .

    I haven't had any enlarged or

    I haven't had any enlarged or cancer in lymph nodes, but others on the forum have.  I am surprised none of them responded to your initial question.  That is frustrating to seek information and not get any.  

    I hope your mother is doing well.  Did her doctor explain why the PET scan didnt show the lymph node in February?

    I too am sorry that nobody has responded to your post. It must have slid down the forum page unnoticed, while I was on vacation. 

    My brother had a lump on his shoulder that turned out to be non-cancerous, but they did a biopsy on it regardless.  I have not heard of anyone here on the forum having this experience, but there may be someone. 

    I hope that all turned out well for your mum, and that the lump was not anything serious.  How is she handling her chemo? Its not fun, and no doubt harder on the older person (our member Danker) did chemo at a higher age, but now, apporaching 85, he is doing wonderfully. 

    I wish your mum the best of luck, and I hope that you post back on the forum and forgive us for not answering your post promptly.
