Does "Bad Luck" Cause Cancer?

Cancer is a dreaded disease and is the second most common cause of death. All cancers are not same. There are good cancers and bad cancers. Also our understanding about what causes cancers has improved over time but still we need to know more.
In what way "luck" can play a role in cancer formation?
Well, the mutations, that is the damage which happens to the DNA, can be random and as it depends on chance, it can be attributed to luck.
So, scientists say, two thirds of cancers can be attributed to bad luck!
The agents which cause damage to DNA like tobacco, alcohol, UV rays, certain chemicals of course increase your "bad luck"!

The chances of developing cancer and bad luck are related to driving an auto mobile! The longer the drive/journey greater is the risk of cancer. Want to understand more about this analogy, read the article below.

1. The mechanical condition of the car is equivalent to inherited genetic mutations. The number of problems in the car—bad brakes, worn tires —increases the risk of an accident.
2. The road conditions on the way to the destination could be likened to the environmental factors in cancer. Worse conditions —slippery roads, poor visibility, dangerous curves—would be associated with a higher risk of an accident
