Quitting Smoking After a Cancer Diagnosis

You may already know that smoking puts you at higher risk for developing cancer including but certainly not limited to lung cancer. All told, it’s estimated that cigarette smoking causes nearly 32 percent of all cancer deaths in the U.S., according to the American Cancer Society.


But just because you have been diagnosed with cancer doesn’t mean that there’s no benefit to be had from quitting smoking. A lot of people may think “the damage is already done, so why not continue smoking?” The truth is it’s never too late to get the benefits of living smoke-free. Quitting smoking is one of the best things you can do following a cancer diagnosis to benefit your treatment.


A cancer diagnosis doesn’t mean you’re immune to developing other diseases or even other cancers. In fact, surviving one type of cancer puts you at a higher risk of developing another, especially if you smoke.  Additionally, smoking increases your risk of high blood pressure, plaque build-up in the arteries that can cause heart complications, emphysema and COPD, among others. Smokers are six times more likely to have a heart attack than non-smokers.


Quit now to be as strong as you can be before during and after cancer treatment.

Before Treatment

As it directly relates to your cancer diagnosis, research has shown that smoking can make the side effects of cancer treatments like chemotherapy and radiation worse on your body. Even six months following treatment, smokers reported more side effects than non-smokers. Patients who quit right before their treatment reported levels of side effects similar to non-smokers. Again, it’s never too late.

During Treatment

If you do smoke while receiving cancer treatments, especially if your treatment involves surgery, your body may have a more difficult time recovering. Smoking negatively impacts your heart, immune system and even your body’s ability to heal from wounds. There is some evidence that suggests smoking even changes the way your body processes chemotherapy drugs, making them less effective.  

After Treatment

Smoking can continue to put you at a higher risk for developing other types of cancer or increase the likelihood for cancer recurrence.


If you have cancer and are in the mindset that you have nothing left to lose, think again. Quitting cigarette smoking after receiving the news of your diagnosis can be beneficial to your treatment outcomes and long-term health.
