I was on my way out the door and didn't have the time to dive into the chart much, but can tell you two things.
Jupiter rulers you, Venus rules the sickness (if there is one). you're far stronger than Venus. Moon rules 8th, even when she comes to sextile Jupiter she will receive him and therefore protect his interests.
like I said, didn't get to dive in to see what kind of sickness could be happening, but I think you can rule cancer out. and whatever it is, your significator strong is a good sign.
