When it is stated that two thirds of cancers are based on luck, it means that the development of cancer is primarily due to random mutations in the DNA of cells, rather than being caused by external factors such as lifestyle choices or environmental exposures.
No, lifestyle choices such as smoking, poor diet, and lack of physical activity can still increase the risk of developing cancer. However, these factors are estimated to contribute to only about one third of all cancer cases.
The statistic that two thirds of cancers are based on luck comes from a study conducted by scientists at Johns Hopkins University. They analyzed data from previous studies on cancer mutations and determined that about 66% of cancer cases are due to random mutations.
Yes, having a family history of cancer does not necessarily mean that an individual will develop cancer. While genetics can play a role in cancer risk, it is estimated that only about 5-10% of cancers are inherited.
The finding that two thirds of cancers are based on luck highlights the importance of early detection and regular screenings, as well as the need for continued research in understanding the role of random mutations in cancer development. It also emphasizes the need for personalized treatment approaches, as the underlying causes of cancer may differ between individuals.
