Kind of Freaking Out

So for the past week or two, I have been dealing with some personal physical issues with my body, but pretty much when I went to go get it checked out, some doctor asked if I had a history of cancer in my family (which I kind of do). Not only that, I have this variation of this illness which is more uncommon and can lead to an underlying problem. I am taking medicines to help with it, but I don't think it's helping all that much.
