Brain cancer is a very deadly disease. Thousands are die each year in the U.S because of it. There is no proven way to prevent brain cancer, and even if it is treated with surgery, a new tumor might appear, and it sometimes can't be destroyed completely. Depending on the type of brain tumor, the survival rate can be as low as 10%. My best friend had stage 4 brain cancer and did not survive. Brain cancer causes great suffering and is a huge problem in our society today. More research needs to be done in order to find a way to prevent this disease. Please sign my petition if you agree.
