I was diagnosed with breast cancer in 2008. I had chemo, lumpectomy and radiation, in that order. Just hit the magic 5 year mark last year. Now, I feel a lump on the bone behind my right ear. Now, a little history...Ive had hearing problems for the past 10 years and Ive had ringing in my ears for about the past 7 years. Of course, Im worried that this might be cancer. Ive made an appt. with the family doctor to have this looked at but Im a real worry kind of person.
Hi. Nice to know you have crossed 5 years-this itself makes that this swelling my not be a cancer. Well, to the facts-Lump behind the ear is not really known to have a cancer. This is most probably a lymph node and develops due to some scalp problems like Dan Chat Doctor.  You can confirm this by FNAC ASAP. To me this can not be a cancer.
