I'm so sorry to hear about your mother!
Yes - Hospital's due have a tendency to treat cancer patients like chopped liver.

They generally aren't funded for specialized cancer treatment and try to use general staff to handle the job. This has been my biggest beef with hospitals who include "Cancer" treatment in their sales pitch. They are like McDonalds adding taco's to their menu then claiming they are a Mexican restaurant...It just doesn't make it so. These same hospitals fight against actual cancer treatment centers when they try to set up a facility in communities. The regular hospitals cannot offer the type off immediate services necessary for cancer patients - yet they don't want to allow treatment centers who speicalize in cancer to take their profits!
In regular hospitals, a cancer patient often has to wait for kids with broken leg or pregnant mothers to be seen first before they can get an appointment for their CT and Ultra sound scans.. This is terrible because cancer is life threatening and time is of the essence when diagnosing and treating it!
I was so disgusted with my so-called cancer hospitals where I live that I contacted the Cancer Treatment Centers of America and I fly to another state for treatments at one of their facilities. They work the flight costs out with your insurance so you don't have to pay out of pocket. At the treatment center - they do everything in one place. A huge facility. In one day they check your blood, give you a complete evaluation and perform CT and PET scans. The next day you meet with the doctors and discuss your cancer and treatment options. They have guest rooms to stay in and a dining area for food and you can bring a family member to be with you. You can't get this type of service at any regular hospital or even some local "cancer" hospitals..
I'd give them a call if you are still not satisfied with your mothers care.
