What is the genetic probability of cancer?

The main cause of cancer is malignant lesions caused by the stimulation of their own cells in the external environment. Although inheritance also plays a certain role, genetic factors play a relatively large role in cancer accounting for 5% of all cancers. Most cancers are more closely related to acquired environmental factors. Those tumors closely related to inheritance can be divided into two categories: one is completely determined by genetic genes, and the other is tumors with certain genetic tendencies. The first type of inherited tumors, more common in some children, while the second type of tumors with genetic predisposition, also known as genetic tumor syndrome, is generally caused by genetic abnormalities.
