What changes when you quit
What changes when you quit
Quitting smoking doesn’t erase the past, but it does change what happens next. From the moment you stop, your body begins repairing damage and your cancer risk starts to shift in a safer direction.
In the first day...
- Your body stops taking in cancer‑causing chemicals. Oxygen levels recover and cells are no longer being damaged by smoke.
In the first few weeks...
Your lungs start clearing out toxins and damaged cells begin repairing. This helps lower ongoing harm that can lead to cancer over time.
Longer term...
The longer you stay smoke‑free, the more your risk of smoking‑related cancers continues to drop. Each smoke‑free day helps protect your body from future damage.
