Oh wow. This is why you go to the gyno every year, ladies. Also never become 600 lbs.
Now thinking about it, the signs have been there for atleast 6 months. She has complained lower back pain, her skin has looked sickly for a while and a sudden weight loss. Missing periods for years is a huge fucking warning sign with neon lights. She had severe bleeding, it's not really looking good in terms of what stage it is. It could have spread, lowering the survival rate. Almost feel bad for her, but she could've avoided this so easily. Yearly gyno, don't abuse your body, take care of your body when you have symptoms, these things won't protect you from it completely, but lower the chances and help catching it earlier. She has made the risks unneccessarily high, all voluntarily.
Due to her weight the usual first line of action, a hysterectomy, is impossible. Her chances of dying on the table are probably higher than surviving cancer without removal of the uterus. Being super morbidly obese will mess with chemo, fat cells in the body produce enzymes which make some chemo drugs less effective. She would need extremely high doses, raising all risks of chemo, and make her very sick. Atleast she has a shot at reaching normal body weight with throwing up 24/7.
If she had taken any kind of care of her body, truly attempted therapy and losing weight, I would feel bad for her. Feels so shitty to say but this could've been catched earlier, if not avoided completely had she taken basic care of her body. Her panic seems genuine, and she should be scared, her chances are shitty. If she survives this, she should be fucking grateful and change her whole life.
