Many cancer survivors struggle to maintain an active lifestyle

“Those who cope best with cancer treatment are often those who had an active lifestyle before diagnosis. It reduces the risk of delayed injury and complications,” says Benedikte Western.

In her doctoral work, she examined 34 different studies, all of which involved cancer patients partaking in exercise programs. She noticed several common traits among those who started but dropped out of the studies. One of them was that they did not have an active lifestyle before getting cancer.

“Their dropping out midway compromises the research. It skews the results when those completing the program already led active lives prior to their illness. After all, they aren’t the ones this research is aiming to help,” says Western.

Typically, those who did not complete an exercise program following cancer treatment were overweight and had less formal education.

However, some exercise programs had more dropouts than others, and people quit at different times. Some exercised regularly during treatment but quit afterwards.

‘Who quits isn’t random’

“We need to bear this in mind when we design these studies. Who quits isn’t random, and for us to find effective solutions for everyone, we need to give extra attention to those who are more likely to quit,” says Western.

It is naturally easier to stick with existing good habits than to form new ones. For many, cancer treatment alone is challenging enough, and in some cases the treatment itself can result in functional impairments.

“Many cancer survivors struggle with fatigue and feel that resting doesn’t help. Sleep is often affected, and some have to remove a lot of tissue or skin. Hormonal levels can also be affected. Adding a lifestyle change to all this can be tough, but simply avoiding it won’t make things any better,” says Western.

Lasting change

Adopting a more active lifestyle can be challenging and mostly depends on the individual. Therefore, Western also investigated so-called ‘self-management skills’—the ability of cancer survivors to make a lasting lifestyle change.

“Changing people’s behavior is complex. That’s why we need more knowledge about what people need help with, and what they believe they can handle on their own. Everyone’s backgrounds and starting points are unique, the key is to figure out what contributes to permanent changes,” says Western.

She discovered that those reporting higher levels of physical activity were also generally more actively engaged in life. They had hobbies and activities they felt gave their lives value. They also monitored their health, had reasonable expectations of themselves, and insight into what influenced their health.

High chance of getting cancer again

“The aim is to find out which characteristics can help cancer survivors become more physically active. It’s a big challenge that requires resources, personnel and different offers for different people. Right now, support to cancer survivors is quite arbitrary,” says Western.

An often under-communicated risk is that cancer survivors have a high chance of getting a different type of cancer. This could be due to the cancer treatment itself but is also largely related to lifestyle. That makes the efforts to encourage cancer survivors to get active even more important.

“Many people are left with seriously deteriorated health after surviving cancer. It’s not something you just get over. That’s why it’s important to offer the survivors a way of being physically active that is sustainable,” says Western.
