Cancer is not an inherited diseases in most cases because Option C: The genetic alterations in most cancers arise mostly in the DNA of somatic cells during the lifetime of the affected individual.
While some cancers do run in families, the majority of cancers cannot be completely linked to the genes our parents passed down to us. Gene changes that start in a single cell over the course of a person's lifetime cause the majority of cancers.
Cancer-causing genetic mutations can be inherited or result from certain environmental exposures. Additionally, mistakes that occurs during cell division might result in genetic alterations. Cancer is, in fact, a genetic disease. Changes in the genes that govern how cells divide and grow are the cause of it.
