“You can be a victim of cancer, or a survivor of cancer. It’s a mindset.” – Dave Pelzer
Cancer diagnosis is not a death sentence. Over half of the people diagnosed with cancer are still alive 10 years later and this number is rapidly improving. With breast cancer about 80% survive at least 5 years and the earlier the diagnosis the better the survival rate. With colorectal cancer about 50% survive at least 5 years and again the earlier the diagnosis the better the survival rate. It is estimated that 14,483,830 adults and children with a history of cancer alive in the United States today. So, there are a vast number of cancer survivors.
Surviving cancer carries with it a number of problems. “Physical, emotional, and financial hardships often persist for years after diagnosis and treatment. Cancer survivors are also at greater risk for developing second cancers and other health conditions.” National Cancer Survivors Day. Unfortunately, most of these residual problems go untreated. Psychologically, cancer survivors frequently suffer from anxiety, depression, mood disturbance, Post-Traumatic Stress Disorder (PTSD), sleep disturbance, fatigue, sexual dysfunction, loss of personal control, impaired quality of life, and psychiatric symptoms which have been found to persist even ten years after remission.
Less well known is that cancer survivors frequently suffer from residual cognitive impairments that affect the majority of survivors and can last for many years. These include problems with attention, including divided attention and multitasking, memory, including short and long-term memory and retrieval, and executive function. These impairments in the ability to think and the extra energy needed for routine cognitive activities can increase fatigue over the day.
Mindfulness has been shown to help with cancer recovery and help to alleviate many of the residual psychological symptoms (see http://contemplative-studies.org/wp/index.php/category/research-news/cancer/) and it has been shown to improve cognitive function (see http://contemplative-studies.org/wp/index.php/category/research-news/cognition/). So, it would seem reasonable to postulate that mindfulness might help in alleviating the cognitive impairments occurring in cancer survivors.
In today’s Research News article “Randomized controlled pilot trial of mindfulness-based stress reduction for breast and colorectal cancer survivors: effects on cancer-related cognitive impairment”
Johns and colleagues examined the effect of an 8-week Mindfulness-based stress reduction (MBSR) program on cognitive function in cancer survivors and compared it to an 8-week Education and Support (ES) program involving comparable amounts of time. They found that the MBSR group in comparison to the ES group showed greater improvements in overall attentional function, particularly with effective action and attentional lapses. The MBSR group also showed greater improvement in ability to cope with cognitive interference as measured by the classic Stroop test. These improvements were lasting as they were still present 6-months after the conclusion of treatment.
These are exciting results as they are in comparison to an active control condition and they suggest that MBSR is an effective treatment for the cognitive impairments in cancer recovery patients. There are a number of explanations for how MBSR might produce these improvements. MBSR targets stress and has been shown to effectively reduce psychological and physiological stress responses. This stress reduction could greatly help the survivors deal with their residual problems. MBSR also markedly improves attention, particularly present moment attention. This may fairly directly help improve cognitive function. MBSR also improves emotion regulation. This may make the survivors better able to cope with the emotional sequela of cancer recovery. Finally, MBSR has been shown to improve cognitive function in healthy individuals and may simply be improving overall cognitive function and not specifically treating the cognitive symptoms of cancer recovery.
Regardless of the explanation, it is clear that mindfulness training is effective in alleviating the cognitive problems following recovery from cancer.
So, improve thinking after recovery from cancer with mindfulness.
