I created this website in 1998. I try to update this list of cancer resources every couple of years, but there's no way for me to be as up-to-date as you want when it matters. These resources are simply suggestions, jumping off points. Everybody needs a place to start.
New to cancer? You might find it useful to look over the materials at OncoLink. This site supports both patients and their doctors/nurses, so it includes a mix of both general information and support, as well as links to drug descriptions and cancer research journal articles.
Cancer.Net is another informative site, this time brought to you by the doctors (the oncologists).
If you are the parent, relative, teacher, or friend of a child with cancer, you might want to check out the American Childhood Cancer Organization site.
You might also benefit from becoming involved with an online cancer community specific to the cancer in which you're interested. The Association of Cancer Online Resources (ACOR) site lists 142 separate online groups, operating as separate mailing. List participants include doctors and patients, both of whom may have information on the latest treatments and clinical trials. Messages in these lists are NOT found via search engine, so it's important to sign up to get connected. Even a cancer as rare as leiomyosarcoma has over 1000 participants in its online group.
If you are looking for information on sarcomas, you can try the Sarcoma Alliance. The site has information on the different types of sarcoma, contact info for sarcoma specialists in your area, as well as support groups and a Peer-to-Peer network.
