Immune therapies finally working against cancer

ORLANDO, Fla. (AP) -- First there was surgery, then chemotherapy and radiation. Now, doctors have overcome 30 years of false starts and found success with a fourth way to fight cancer: using the body's natural defender, the immune system.
The approach is called a cancer vaccine, although it treats the disease rather than prevents it.
At a cancer conference Sunday, researchers said one such vaccine kept a common form of lymphoma from worsening for more than a year. That's huge in this field, where progress is glacial and success with a new treatment is often measured in weeks or even days.
Experimental vaccines against three other cancers - prostate, the deadly skin disease melanoma and an often fatal childhood tumor called neuroblastoma - also gave positive results in late-stage testing in recent weeks, after decades of struggles in the lab. LinkHere
