World Cancer Day was founded in 2008. Its aim is to raise awareness of cancer and to encourage the prevention of this terrible disease. The day was established in order to reduce illness. Today people are taught to detect and treat cancer. There is even a special movement known as #NoHairSelfi. "Hairticipants" of the movement shave their heads (physically or virtually). Thus, they show their respect for people who undergo cancer treatment.

Have you even heard about such day? Please, tell us in the comments below!
