Breast Discharge

I have a tumor on my left breast behind the nipple. Never had surgery to remove bc the cancer already advance to the bones. Over the years the the tumor has been sucking the nipple inward. So, I would have to clean it with a baby q-tip. Last year I had brain radiation bc mets to the brain and my skin started to get dry and so did my nipples to the point where a piece of nips fell off. Now I’ve been having gooey yellowish sometimes a little blood discharge everyday. I put a bandage on every morning sometimes there’s a light discharge and sometime it’ll soak the bandage. I will see the onco soon on my next appt but want to check here if anyone hasn’t experienced rhis
