What kind of chemo are you on. Avastin can cause nose bleeds, but the other chemo can still dry out the mucous membranes in the nose and cause the more "minor" bleeding you are talking about. I have been having the bleeding when I blow mine also for a couple of weeks. I thought my platelets were too low again (since that happened last time they were low), but my oncologist also said I had some inflammation in the nose that needed to heal and gave me Nasonex to try. It seems to help some, but I am still having some blood, but not as bad.
Diagnosed Dec 2005 stage 3C
LAR Dec 2005
Mom finished chemo for stage 3B Jan 2006
I had chemo Feb 2006-Aug 2007
