One of the really tough things about receiving a cancer diagnosis is not knowing what to do next. You don't even know what you don't know.

Over the last few decades, the ability of doctors to successfully treat childhood leukemias has risen dramatically. For the small group of patients that don't respond to initial therapy, figuring out why has become an important research topic.

Telomeres  are like the caps at the end of poster tubes. They are found at the end of chromosomes and help protect genetic data. Scientists have discovered that the length of telomeres  can help predict liver cancer risk.

More and more studies are showing that the best treatment for a given type of cancer may not be the same for everybody. A new study looking at prostate cancer adds to the growing amount of evidence supporting individualized treatment.

For most skin cancers, a simple excision is enough. But in some cases, doctors might decide to have the cancer examined under microscope to make sure it was removed completely.

Chemotherapy, as well as other pharmaceuticals, are key components of cancer treatment. But sometimes the drugs stop working as the cancer becomes immune to the drug. Research is now focusing on reversing that drug resistance.
