How do you get cancer from cells?

Cancer is a disease caused when cells divide uncontrollably and spread into surrounding tissues. 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.

Can cancer cells survive outside the body?

Does everyone have cancer in their body?

No, we don’t all have cancer cells in our bodies. Our bodies are constantly producing new cells, some of which have the potential to become cancerous. At any given moment, we may be producing cells that have damaged DNA, but that doesn’t mean they’re destined to become cancer.

What is finger clubbing and how does lung cancer cause it?
