My mom had been complaining about
loss of appetite, indigestion and feeling bloated (as if there was a lump/knot behind her belly button).
She coughed up a bloody sputum ~6 months ago once (she had fainted around that time as well, I'm not sure if she fainted on the day she coughed up blood itself or not), she hasn't coughed blood since, and hadn't coughed noticeably until a few days ago, she has no fever..
