What is the main cause of all cancers?
Cancer is caused by changes (mutations) to the DNA within cells. The DNA inside a cell is packaged into a large number of individual genes, each of which contains a set of instructions telling the cell what functions to perform, as well as how to grow and divide.

How do cancers spread?
When cancer spreads, it’s called metastasis. In metastasis, cancer cells break away from where they first formed, travel through the blood or lymph system, and form new tumors in other parts of the body. Cancer can spread to almost anywhere in the body. But it commonly moves into your bones, liver, or lungs.
How do most cancers arise?
Cancer is caused by changes to DNA. Most cancer-causing DNA changes occur in sections of DNA called genes. These changes are also called genetic changes. A DNA change can cause genes involved in normal cell growth to become oncogenes.
Are eggs a carcinogen?
From these results it appears that both egg white and egg yolk are carcinogenic, but that their carcinogenicity differs. A carcinogenic substance causing the development of lymphosarcomas and lung adenocarcinomas, would be present in both, while a mammary carcinogen, lipid in nature, is present in the yolk only.
What is the strongest carcinogen?
Aristolochic acid—one of the most potent carcinogens known to man.
