Is cancer a clonal process?

What does clonal mean in cancer?

Clonal evolution suggests that expansion of a population of cancer cells from an individual single-cell causes tumor heterogeneity in pathology and molecular profiles with acquired genetic and epigenetic changes (Stingl and Caldas, 2007).

Do cancers evolve?

Since cancer is a disease driven by DNA mutations, its story is also one of evolution. Cancer cells that develop harmful mutations to themselves experience decreased growth and reproduction, and over time can disappear from the tumor.

Do all cancers have driver mutations?

Rare driver gene mutations are likely to be present in less than 1% of cancers. Scientists have considered a theoretical basis to explain why some driver mutations are rare.

What is clonal growth?

Clonal growth, vegetative reproduction in which offspring remain attached to the parent at least until establishment, is common in plants and in ecosystems around the world and appears to be associated with the invasiveness of introduced plant species.

How many mutations does it take to make a tumor?

Experts agree that it takes more than one mutation in a cell for cancer to occur. When someone has inherited an abnormal copy of a gene, though, their cells already start out with one mutation. This makes it all the easier (and quicker) for enough mutations to build up for a cell to become cancer.
