New lump found

Hi everyone  my names Tracy and I am new to this forum.

 

I have invasive ductal cancer grade 3 and have just been through my fourth cycle of chemotherapy. I am quite worried at the moment because although I have been told that things are looking good after my last MRI scan, unfortunately I have just found a new lump. Has anyone else had this happen? I have only just told my oncologist so I don't yet know if it is cancerous.
