Cancer /ˈkænsə(r)/ ( listen) (medical term: malignant neoplasm) is a class of diseases in which a group of cells display uncontrolled growth (division beyond the normal limits), invasion (intrusion on and destruction of adjacent tissues), and sometimes metastasis (spread to other locations in the body via lymph or blood). These three malignant properties of cancers differentiate them from benign tumors, which are self-limited, and do not invade or metastasize. Most cancers form a tumor but some, like leukemia, do not. The Cure for these sickness is step-by-step discovered. People are afraid to have this kind of sickness because it can lead to death.

I was watching TV in the morning. The TV program is a news program. One of the news is the green tea which can prevent cancer sickness. They said that green tea has an anti-cancer particles/components which can prevent cancer. "Drink one glass of green tea a day to prevent cancer" they said. For me, "Prevention is better that cure", you must have a healthy lifestyle to avoid sickness. Eat balanced diet, eat vegetables and have a proper exercise everyday to become a physically fit (healthy mind and body) person.
