If you're having trouble finding information about a type of cancer, it may be a rare cancer or have more than one name. It might also be a condition known as a pre-cancer, which is something that might lead to or turn into cancer later. The links below might help you find the information you need.
Rare cancers are not as common as other cancers. Because fewer people have had them, less is known about them, and information might be harder to find.
Some cancers are so rare that only a small number of people are diagnosed with them each year. What is known about each type of cancer is usually learned from clinical trials and doctor's experiences treating people with that cancer type. Because not many people have these rare cancers, they may not have been studied in clinical trials, and some doctors might not have taken care of anyone with them. Much of the information about these cancers comes from case studies, where doctors share the experience of one patient so that others can learn about it.
If you or someone you know has a rare cancer, you may need to travel to find a doctor or cancer center that has experience treating that cancer. Larger cancer centers or hospitals are also more likely to have clinical trials (research studies) you might be able to take part in. ACS has information that can help you choose a cancer center or hospital or choose a cancer doctor.
The list below includes cancerous and pre-cancerous conditions (as well as some other conditions that might be related to cancer) and where to find more information about them.
