Why does cancer exist?
Usually the number of cells in any of our body tissues is tightly controlled so that new cells are made for normal growth and development, as well as to replace dying cells. Ultimately, cancer is a loss of this balance due to genetic alterations that "tip the balance" in favor of excessive cell growth.
Why is 5 year cancer free important?
If you remain in complete remission for 5 years or more, some doctors may say that you are cured. Still, some cancer cells can remain in your body for many years after treatment. These cells may cause the cancer to come back one day. For cancers that return, most do so within the first 5 years after treatment.

Cancer cells or tumors in organs or the bloodstream can disrupt organ function. They may destroy healthy cells in organs, block their nutrient or oxygen supply, and allow waste products to build up. If cancer becomes severe enough that it impairs or prevents vital organ function, it can result in death.

Has anyone survived stage 4 cancer?
Evolution seems to have favored some relatively common resistance genes that protect the majority of humans against cancer development. One day, finding out how nature keeps most of us cancer-free could help identify and repair specific genetic mechanisms in the large minority of individuals who do suffer from cancer.

Cancer cells do not exist in the body for everyone. The human body is constantly in a cycle where new cells grow, divide, and die in a controlled manner, a process known as apoptosis. Usually, cells with damaged DNA either fix themselves or die naturally.
Do dead cancer cells hurt?
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.
Can you fight cancer on your own?
Lung cancer doesn't usually cause symptoms until it's advanced (also referred to as late-stage cancer). That's because your lungs have few nerve endings, so tumors can grow there without causing pain.
