A team of South Korean scientists say that they have developed a new cancer treatment.

Professor Kang Chang-yuil of Seoul National University said Tuesday that the new treatment can vitalize immune cells in the blood within a day and cut costs by ten percent.

In developing the alternative treatment, Kang’s team separated weak B cells from one patient and enhanced them with T cells, a type of immune cell. The results proved to effectively control the growth and mutation of cancer cells.

A lab mouse injected with the new vaccine responded within two to three days and, after two to three weeks, two types of cancers including breast cancer were cured.

Kang published the paper in the latest edition of Cancer Research, a leading international cancer treatment journal.
