It may seem unbelievable to someone who doesn\u2019t smoke, but lighting up after a cancer diagnosis is more common than you might think.\nIn fact, according to one recent study, nearly 10 percent of cancer patients continue to smoke years after their diagnosis, with the majority of them doing so on a daily basis. People who have had cancer of the bladder, ovaries, and lungs are even more likely to keep smoking. Overall, cancer survivors who smoked light up an average of 15 cigarettes a day.\nThat\u2019s a concern, because smoking is not only dangerously unhealthy, but can also make you less likely to respond to your cancer treatment. Here are four good reasons why it\u2019s time for cancer survivors to quit for good.\n\u201cCancer diagnosis is a great time to quit smoking because it can increase survival rates and reduce the chance of cancer treatment complications and significantly improve quality of life,\u201d says\u00a0Lanie K. Francis, MD, medical oncologist and program director at the Wellness and Integrative Oncology Program at UPMC Hillman Cancer Center.\nLearn more by visiting the UPMC Smoking Cessation website.\nWhy You Should Quit Smoking After a Cancer Diagnosis\nQuitting lowers the chance of cancer recurrence\nSmoking doesn\u2019t just increase the chances of lung cancer returning. It can also raise the risk of other cancers recurring, including those involving the larynx, throat, mouth, kidney, bladder, liver, and pancreas.\nSmoking can cause chronic health problems\nEven if you\u2019ve beaten cancer, smoking still makes you vulnerable to a slew of other chronic conditions, from cardiovascular disease to diabetes.\nSmoking limits the effectiveness of your cancer treatment\nSmoking can alter the way your body processes chemotherapy drugs and increases your chance of developing complications from this cancer treatment.\n\u201cSmoking during cancer treatment can increase the toxic side effects from chemotherapy and decrease your response rate to chemotherapy and radiation,\u201d Dr. Francis says.\nSmoking can worsen your treatment side effects\nCancer treatment can be hard on your body, even if you\u2019re otherwise healthy. Smoking makes side effects (such as fatigue, nausea, hair loss, and pain) worse, even months after treatment has ended.\n\nTips to Help You Quit\nThat\u2019s powerful evidence of the importance of quitting tobacco. But for many people, that\u2019s easier said than done.\n\u201cWhile cancer diagnosis is a stressful time, many patients want and can quit smoking with tools such as nicotine replacement and support from their care team,\u201d Dr. Francis says.\nThe first step is to set a quit date \u2014 and stick to it. Remember, there is no one-size-fits-all option when it comes to choosing your quit method. Different methods may be more effective than others, depending on your lifestyle and personality.\nOptions include going cold turkey; tapering the number of cigarettes you smoke each day over a specific period; using smoking cessation products; and seeking professional support. Your physician can tell you more about the best approaches for smoking cessation.\nLearn more by visiting the UPMC Smoking Cessation website.
