Smokers who continue their habit after a cancer diagnosis may assume that quitting wouldn’t make much of a difference. However, a recent study published in JAMA Oncology on October 31 reveals that quitting smoking following a cancer diagnosis can greatly improve survival rates.

The study, led by Paul Cinciripini, chair of behavioural science and executive director of the Tobacco Research and Treatment Program at the University of Texas MD Anderson Cancer Center, found that smokers who quit shortly after their diagnosis were 22 per cent to 26 per cent less likely to die compared to those who continued smoking. “Our research underscores the critical role of early smoking cessation as a key clinical intervention for patients undergoing cancer treatment,” Cinciripini explained in an MD Anderson news release.

Researchers tracked more than 4,500 cancer patients enrolled in MD Anderson’s quit-smoking program, where nearly all support was provided via telemedicine. Patients who quit within six months of their cancer diagnosis and stayed tobacco-free for at least three months saw the best results. These patients had an average survival of four years, double that of the patients who continued smoking. The study’s findings show the potential for quitting smoking to add both quality and quantity to the lives of cancer patients.

The study also brings attention to a gap in routine cancer care. Despite widespread knowledge of smoking’s risks, smoking cessation is often underemphasized by oncologists. “While smoking cessation is widely promoted across cancer centres for cancer prevention, it remains under-addressed by many oncologists in their routine care,” Cinciripini noted. He urges healthcare providers and institutions to integrate smoking cessation more prominently in cancer treatment plans.

“This is a call to action for experts, regulatory bodies, and institutions to prioritize smoking cessation as an integral part of first-line cancer care,” Cinciripini said. The findings make it clear that incorporating smoking cessation into cancer treatment could significantly extend life expectancy for patients.

Tips for Quitting Smoking After a Cancer Diagnosis

Cancer patients who are motivated to quit smoking will be able to achieve their goal with the right support and strategies. Here are some tips to follow:

- Seek Support: Joining a support group or enrolling in a quit-smoking program can provide guidance and encouragement. Many cancer centres now offer such services, often through telemedicine, as seen in the MD Anderson program.

- Utilise Nicotine Replacement Therapy (NRT): Nicotine patches, gums, and lozenges can help reduce withdrawal symptoms, making it easier to manage cravings while gradually reducing nicotine dependence.

- Consider Prescription Medications: Medications like varenicline (Chantix) and bupropion (Zyban) can ease withdrawal symptoms and help manage cravings. Talk to your oncologist to determine if these are suitable options for you.

- Find Healthy Distractions: When cravings hit, redirecting your attention can help. Try taking a walk, practising deep breathing, or engaging in a hobby.

- Focus on the Health Benefits: Remind yourself of the benefits. Quitting smoking not only improves survival rates but also enhances quality of life by reducing complications and easing cancer treatment symptoms.

- Build a Support Network: Friends, family, and even online communities can provide valuable emotional support, helping you stay motivated and accountable in your journey to quit.
