2/3 Of Cancer Cases Just Bad Luck
[su_right_ad]Researchers have discovered that 2/3 of cancer incidences are just bad luck because of random mutations.
The researchers said on Thursday random DNA mutations accumulating in various parts of the body during ordinary cell division are the prime culprits behind many cancer types.
They looked at 31 cancer types and found that 22 of them, including leukemia and pancreatic, bone, testicular, ovarian and brain cancer, could be explained largely by these random mutations – essentially biological bad luck.
The other nine types, including colorectal cancer, skin cancer known as basal cell carcinoma and smoking-related lung cancer, were more heavily influenced by heredity and environmental factors like risky behavior or exposure to carcinogens.
Overall, they attributed 65 percent of cancer incidence to random mutations in genes that can drive cancer growth.[su_csky_ad]
