The claim that cancer is hereditary is too absolute and unscientific. Most cancers, such as breast cancer, colon cancer, lung cancer, nasopharyngeal cancer, etc., have a certain hereditary tendency, but cancer is not necessarily hereditary.
Cancer is the crazy growth and division of cells, uncontrollable reproduction, and invasion of surrounding normal cell tissues, through the body circulatory system to other parts of the body, cancer is mostly malignant tumors.
Breast cancer, colon cancer, thyroid cancer and other malignant tumors are hereditary to a certain extent, but immediate family members with cancer are not necessarily able to develop cancer. A number of studies have proved that many kinds of malignant tumors have a certain degree of family aggregation, and if the immediate family members have malignant tumors, the chances of developing cancer are higher than that of families without malignant tumors.
It is recommended that people with hereditary predisposition to cancer should go to the hospital for regular medical checkups for early prevention of cancer.
