Gene mutations that occur after birth. Most gene mutations occur after you’re born and aren’t inherited. A number of forces can cause gene mutations, such as smoking, radiation, viruses, cancer-causing chemicals (carcinogens), obesity, hormones, chronic inflammation and a lack of exercise.

Which body part Cannot be affected by cancer?

The heart, in contrast, doesnt get exposed to many carcinogens, just those in the blood.

Do we all have cancer?

No, we don’t all have cancer cells in our bodies. Our bodies are constantly producing new cells, some of which have the potential to become cancerous. At any given moment, we may be producing cells that have damaged DNA, but that doesn’t mean they’re destined to become cancer.
