Question: Friend with very large swollen abdomen - NOT pregnant - went from 98 lbs to 140 lbs in one month...? My friend - prone to exaggeration - has had horrible health problems, kidney stones, surgeries to remove kidney stones, genetic hypophosphatemia, sarcoidosis- anyway - in one month this 30 year old woman went from 98 lbs to 140 lbs. she looks pregnant but she has swelling all over her body. 100% sure not pregnant - went to emergency room where she says they told her she has a 30 lb tumor on her kidney. Is this even possible?? what else could it be? you can see a mass on her right side of her abdomen but would the doctors diagnose that four days ago and let her be home and going about her business as usual with a 30-lb tumor in her body??? If so - if drs are negligent here - what should she do?

Answer: Yes, it's very possible. They should have made a biopsy to see if it is cancerous. If it isn't then she could go through her whole life with that tumor. The surgery in this case is optional. Also there might be veins or other critical organs that could prevent doctors from removing the tumor.
