A fresh look at the causes of cancer has come up with some surprising numbers. While smoking is still by far the biggest cause of cancer and cancer deaths, obesity, poor diet and drinking too much alcohol cause an increasing number of cancer cases and deaths.
Are we born with cancer cells?
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.
Does cancer grow?

Are cancer cells alive?
Cancer cells have unique features that make them “immortal” according to some researchers. The enzyme telomerase is used to extend the cancer cell’s life span. While the telomeres of most cells shorten after each division, eventually causing the cell to die, telomerase extends the cell’s telomeres.

What does it mean when a cell turns into cancer?
This is a mutation. It means that a gene has been damaged or lost or copied too many times. Mutations can happen by chance when a cell is dividing. Some mutations mean that the cell no longer understands its instructions. It can start to grow out of control. There have to be about 6 different mutations before a normal cell turns into a cancer cell.
