There is new hope in the fight against cancer. A woman who had advanced breast cancer is apparently cancer free, nearly four years after taking an experimental vaccine developed by the National Cancer Institute.
The Panvac vaccine was used on 26 patients who had breast or ovarian cancers that had spread to other parts of the body. Most had exhaused all other forms of treatment.
Overall, cancer returned in patients within about two months, and median survival was about 14 to 15 months, except for the one patient who remains cancer free.
Researchers say this small victory gives them hope the vaccine could work for other patients.
