It depends on how much you have smoked and for how long, 40 ciggs a day is very different from 5 a day. A very rough average for people in their 50's who have smoked since they where teenagers is 5-7% chance to develop lung cancer before they reach 65.

Here's a table with approximations: 1 pack a day for 30 years > less than 1%

1 pack a day for 35 years > about 3%

1.5 packs a day for 40 years > about 4%

2 packs a day for 45 years > about 8%

2 packs a day for 50 years > about 15%

Please note that your individual risk varies greatly depending on factors such as personal physice and general living conditions. However it's not at all certain that you will develop lung cancer because you smoke.
