“…With the rapid growth rate of chronic conditions, even among the non-elderly U.S. population, such estimates become increasingly important as cancer patients will likely have more comorbid conditions that will need to be managed, while the patients undergo potentially intensive cancer combination therapy involving surgery, chemotherapy and radiation (Imai, Gregg, Cheng, & Zhang, 2006;Partnership to Fight Chronic Diseases, 2009;Boyle, Thompson, Gregg, Barker, & Williamson, 2010). The higher rate of cancer complications and exacerbations of comorbid conditions among individuals with underlying comorbidities may explain this increase in the cost during the treatment phase, which can add significantly to the overall increasing cost of care (Srokowski, Fang, Hortobagyi, & Giordano, 2009;Peters et al, 2011;Lee, Cheung, Atkinson, & Krzyzanowska, 2011). It is also possible that individuals with underlying comorbidities are receiving additional services, because they are in contact with providers more often due to their cancer diagnosis.…”
