Hello! I am new to this site. I need some help. I got some red spots on my arm with lymphedema and I don't know how it started. Saw my primary doctor yesterday and requested some lab work done. Also saw my oncologist and requested an ultrasound done on the arm. The red spots started about 5 days ago and it is spreading up to my armpit. And it looks like measles to me. I will be traveling to Alaska on the 21st and I want to know if this is a big problem. Was diagnosed with cancer in 2007, went through mastectomy, chemo, radiation and a year on Herceptin. Three years later, in April of 2010, cancer came back and metastasized to liver and lungs. Was in chemo for one year, and last April. CT scan of pelvis, chest and abdomen showed no tumor. So doctor stop chemo treatment and now on Herceptin for maintenance.
