I have a lump in my lower back on left side. it is getting bigger. i have ached and been feverish. my mom had multiple miloma cancer and my son has acute myeloid leukemia.

Likely due to infec-: tion, because of the fever. You need an examination as well as a good family history to determine how many relatives have developed a cancer. There are rare familial cancer predisposition genes that may be tested for, if appropriate, like Li – Fraumini syndrome. Ask for the age at onset and what tissue was first affected, then obtain a local cancer genetics consultation or on Healthtap
