Grandmother named Zhang Ruifang, lives in Henan Province and it is 100 years old.
Horn in Zhang Ruyfang began to grow in the past year.
He now has a length of about 6 inches. According to doctors horns began to grow due to metabolic disorders. These growths are called atheromas in medicine. They appear if the person's head clogged hair follicles. However, the case of the Chinese grandmother is unique: the contents of the hair follicles stiffly. In short, turned into bone. Most interesting is that on the right side of the forehead Chinese women have formed the same lump, which is likely to eventually become the second horn.
