Cancer is very big and danger disease. And if it reach in final position then it is very difficult to save a patient from death. And I saw many patient in my relatives who has this disease and they died due to cancer. Even that there is a child in my relative who has cancer disease , but she recover and get good health after recovery. But she is in the early condition. thats why she recover. And I like that you want to eradicate this caner disease. Good luck for the contest
