What is cancer and what happens to make it occur

Cancer is a disease in which abnormal cells divide uncontrollably and destroy body tissue.

Explanation:

Cancer is caused by gene mutations, which are sometimes caused by inherited gene mutations (ones you are born with), or mutations that occur after birth (i.e smoking, being overweight, chronic inflammation, viruses, cancer-causing chemicals (carcinogens), hormones, and lack of exercise.)

Your habits (drinking alcohol frequently etc. )

And family history are the main influences of cancer.

However, inherited cancer is usually rare.
