Scientists at the National Cancer Institute report encouraging results on an experimental cancer therapy.
They treated 9 women with cervical cancer using their tumors to grow T-cells which are part of the immune system, and can target the cancer. Researchers say tumors disappeared in two of the women and they're cancer-free more than a year later.
Scientists are trying to figure out why other women in the study didn't respond to the treatment.
The Human Papilloma virus causes most cervical cancer. Scientists are now testing the therapy on other HPV-related cancers including anal and throat cancers
