What characterizes hereditary cancer?

Hereditary cancer is characterized by its association with inherited mutations in specific genes that can significantly increase an individual's risk of developing certain types of cancer. These mutations are passed down from parents to their offspring and are often found in genes that are responsible for regulating cell growth and repair, such as BRCA1 and BRCA2, which are linked to breast and ovarian cancer.

The presence of these inherited mutations may lead to a higher likelihood of cancer occurring at a younger age or in multiple family members, highlighting the genetic component of this category of cancer. This genetic predisposition can be identified through family medical histories, genetic testing, and counseling, allowing for tailored preventive measures and early detection strategies.

The other options do not accurately reflect the nature of hereditary cancer; for example, hereditary cancer is not exclusively treatable with chemotherapy, does not primarily arise from acquired mutations in non-genetic tissues, and it can develop in individuals of various ages, not just older adults.
