BROTHER DIAGNOSED WITH EMBRYONAL CELL CARCINOMA, NON-SEMINOMATOUS: PLEASE HELP

Hi all...
My brother, age 30, had pain and swelling in his right testicle and felt a lump. An ultrasound confirmed the presence of a mass, the testicle was removed, and a biopsy was done. The tests revealed that the mass was malignant. The doc says it is Embryonal Cell Carcinoma, Non-Seminomatous. My brother will be undergoing a series of CT scans (chest and abdomen), a bone scan, and more blood work.

I have no knowledge of this type of cancer (I'm still a nursing student) and I was hoping that someone out there could provide me with some information. I checked out a few web-sites that were recommended to me, but I still feel as though I need more information.

Does anyone out there have any personal experience with this type of cancer? How aggressive is it? Are there any web-sites, articles, or books you can recommend? I could really use some help. Feel free to email me.

Thanks.
