LOL wow fox news certainly likes be misleading.
Cancer IS caused by genetics.
For those unfamiliar, cancer is controlled by gene expression. A person can have a cancerous gene encoded within their genome, that is not expressed.
Certain triggers, such as exposure to certain chemicals, and radiation, can "turn on the switch" for these genes. These genes, which reside in the
DNA, then get translated into mRNA. The mRNA then leaves the nuclear membrane of its cell, and binds to the endoplasmic reticulum where it transcribes
the code synthesizes actual proteins. These proteins are the building blocks of the cancerous tissues.
Another example of gene expression, that most of us have experienced, is the need to urinate frequently when drinking alcohol. Alcohol suppresses the
production of Aquaporins, which are proteins that reside on the cell membrane responsible for re-uptake of fluids. Aquaporins on the cell membrane are
constantly recycled, so when the production of them is suppressed, they dwindle in numbers, and our body fails to retain fluids.
Diseases don't cause the cancer, but they trigger the expression of cancerous genes. Cancer itself is not contagious.
What we should really be worried about is the day when everybody is required to have a genome mapping done, and thus future diseases and complications
can be accurately predicted. Imagine what insurance companies would do with that kind of information....
