How will your life get better when you quit?
These are just some of the amazing health benefits of quitting smoking. Quitting also lowers your risk of other cancers, including stomach, liver, bladder, and kidney cancers. It improves your fertility and reduces your risk of diabetes. It can also prevent existing health conditions from worsening and can help you heal faster from surgery or infections.
Quitting at a younger age has the most benefits— quitting before age 40 reduces the risk of dying from smoking-related cancers by about 90% — but quitting at any age has incredible benefits for your health.
