Explain the way that spontaneous mutations, sporadic mutations may lead to cancer development, and relate that process to assessment of cancer risk.
Spontaneous mutations can occur in cells as a result of DNA replication errors or exposure to environmental factors, such as UV light or chemicals. These mutations can alter the function of critical genes involved in cell division, leading to the development of cancer. Assessment of cancer risk may involve evaluating an individual’s genetic predisposition, lifestyle factors, and exposure to environmental carcinogens.
Apoptosis is a process of programmed cell death that occurs as a normal part of development and tissue homeostasis.
Autolysis is the self-digestion of a cell or tissue, often as a result of cell death.
Autophagy is a cellular process in which cellular components are degraded and recycled to provide energy and nutrients to the cell.
Approximately 5-10% of cancers are familial cancer syndromes, meaning they are inherited from a person’s parents and run in families.
Mutagen exposures, such as exposure to certain chemicals or radiation, can increase the likelihood of genetic mutations, some of which can lead to the development of cancer.
The most common genetic mechanism leading to the development of cancer is the accumulation of multiple mutations in oncogenes and tumor suppressor genes, leading to alterations in cell proliferation, apoptosis, and DNA repair. These mutations can result from both spontaneous and environmentally-induced processes. Spontaneous mutations.
