my wife lost 20 lbs in feb of 2013 and her stomach kept growing -we had med ins then ,took her to doctor and he was very brief ,looked at her stomach and said she was bloated -gave prescript for it and said take water pills and exlax- by june she had problems holding bowels -legs got swollen,kept wetting herself-now do not have health insurance-doctor wont see us untill we pay a fee up front-so i took her to a obgyn in bradenton fl -who was willing to see her with no ins- she immediatly sent us for a catscan-when results came in they found a 30 pound tumor/cyst, we were then sent to a oncologist -dr.south at manatee hospital-,who told us to go to emergency room since we had no health insurance now and they would get us in right now, the growth was growing quickly was very large ,, at the E.R., they admitted her and by the next morning she had operation to remove growth found to be non cancerous,30 lbs large,she was cut from her breast to vaginal area to remove it.
