New York: US researchers have developed a vaccine to fight against ovarian cancer, and it has shown hopeful results in preliminary trials.

The vaccine, which is developed by researchers headed by Kunle Odunsi at the Roswell Park Cancer Institute in Buffalo, raises the body’s individual immune reaction to the cancer.

The study researchers analysed tha vaccine in women suffering from ovarian cancer, a cancer type, which develops on the ovaries covering.

Lead author, Odunsi said, “There is now compelling evidence that the immune system has the capacity to recognise and kill ovarian cancer cells. We are confident that the vaccine will eventually be widely available.”

Ovarian cancer is the tumour development on or inside an ovary. It normally takes place in women above 50 years of age, but it can also have an effect on younger women. Its cause is still unknown. Treatment is usually surgical operation accompanied by treatment with medications.

The majority of patients with advanced disease react to drug treatments, but over 70% passes away from a reappearance of the cancer within five years of diagnosis.

It is the fourth coarsest type of cancer in women and fifth major cause of cancer death in the United States.
