Cervical cancer, one of the most common cancers in women, is often treated with surgery, radiation, or chemotherapy, which can affect fertility and quality of life. Researchers at Chiba University have developed a new nasal therapeutic vaccine as a non-invasive treatment option. In animal studies, the vaccine produced strong and lasting immune responses against cervical tumors. If proven effective in humans, it could provide women with a safer, fertility-preserving alternative to current cancer treatments.
