Hi Marjorie,
and welcome to the forum. In the long run you'll be glad you found us because we can help take some of the mystery out of this.

The first thing to do is take a deep breath. Remember that many of the stories here are based on the worst case scenario and your mothers experience may be far easier.

It is vital that someone accompany your mother to all of the appointments and take good notes. You are discovering, like the rest of us, that treatment decisions must be made rather quickly.

Among first things you will need to know are the staging and type of cancer. This will be the basis for her treatment decisions.

The PEG is a stomach feeding tube. Typically not a big deal. There is much information on this elswhere on the site. Some of us didn't need one. It is important that you meet with the nutritionist and discuss your options there also.

It sounds very promising that they stated the cancer is "very curable". There have been others here recently with older parents who have gone through this and they will be responding to you also.

Is she being treated at Abramson Cancer Center or a network hospital?
