Insomnia is commonly associated with cancer patients undergoing chemotherapy, it has been revealed.
Researchers at the University of Rochester Medical Center, US, discovered that insomnia occurs in three-quarters of cancer patients and survivors treated with chemotherapy, which can impact on a patient's ability to fully recover.
A study involving 823 cancer patients showed that sleep troubles were experienced at nearly three times the rate of the general population, with insomnia particularly prevalent among younger patients and individuals with lung and breast cancers.
Study lead author Professor Oxana Palesh said that the numbers are so high that they cannot be ignored.
"The good news is that insomnia is a very treatable problem that can be addressed quickly so it doesn't compound other symptoms," she explained.
Among these patients, 37 per cent said they suffered from insomnia symptoms and 43 per cent said they had insomnia syndrome, which is characterised by difficulty falling asleep and staying asleep for at least three days a week.
Away from cancer patients, insomnia tends to be more common among older people, females and those with a history of depression.
