It could be the breakthrough that cancer patients have been seeking for generations.
A clinical trial of 1,000 women who were given two new "drug cocktails" concluded that half of them got their cancers under control. In addition, some with hard-to-treat kidney and lung cancers saw a 30 percent decrease in tumor size.
The drugs, which have similar effects to those of chemotherapy, don't carry the same side effects as radiation.
"It really is like a heat-seeking missile with a toxic payload," XXX said. "(It) travels all over the body until it meets the cancer cell and then lets off a massively toxic dose."
Patients with breast cancer who were given what's called an "antibody drug complex" saw their mortality rate reduced by 38 percent compared to those taking conventional drugs.
For Judy Macon, who survived breast cancer twice, the developments are thrilling.
"The fact that many of the side effects that we associate with chemotherapy can be eliminated...is so exciting," Macon said. "I think this is such exciting news."
