You know that exercise is vital to health and wellness, and physical activity is still very useful in preventing certain types of cancer. Until recently, however, leukemia and myeloma were not enrolled in general among those guys who can cut the risk with exercise.
One study examined the question of exercise and reduced risk of several different types of cancer. The authors noted that one of the principal of their study is that, to its knowledge, is the largest study ever conducted on physical activity and cancer risk.
The researchers published their findings in the May issue of Archives of Internal Medicine 2016. They took note of the current situation and the need for this physical-study activity reduces the risk of heart disease, colon cancer, breast cancer and cancer, but endometrial less is known about whether physical activity reduces the risk of other cancers which actually represent about 75 percent of new cancer cases in the United States.
Exercise and cancer study – FAQ
How common is physical inactivity
It is estimated that 51 percent of people in the United States and 31 percent of the world population do not get the recommended levels of physical activity. Any decrease in the risk of cancer associated with physical activity, can therefore be relevant to health efforts and public cancer prevention.
What is the Leisure Time Physical Activity?
leisure-time activities were defined in this study as activities carried out at the discretion of an individual who improve or maintain fitness or health.
The research group included two categories of leisure activities :. Moderate-intensity activities and other activities that have vigorous intensity levels that are recommended by the guidelines of physical activity
How Did The researchers learn what people developed cancer?
In this study questionnaires were used, but also reviewed the medical records databases and cancer registries.
Overall, 99 percent of cancer cases identified in the study were confirmed by medical records or reports-pathology reviews which pathologists made in the analysis of a sample or biopsy specimen that is to be cancer.
How many people were in this study?
This study was extracted from 1.44 million participants who had complete leisure physical activity data and no history of cancer at baseline.
Most participants, 57 percent were women, the mean age at baseline was 59, and mean body mass index, or BMI was 26. higher activity levels were associated with a younger age, higher education, lower BMI and lower probability of being a current smoker.
How many cancer types studied?
The researchers analyzed 26 different types of cancer. During a median follow-up of 11 years, 186.932 cancers were identified. ¿
What were the results?
A high compared to a lower level of physical activity in leisure time was associated with a reduced risk of 13 of the 26 cancers studied.
-Activity free time was also associated with an increased risk of malignant melanoma, and increased risk of prostate cancer non-advanced.
A higher level of physical activity in leisure time was associated with a lower risk 7 percent of the total cancer.
For myeloid leukemia and myeloma, this study found a strong inverse association, ie, more physical activity was strongly associated with less, however, cancer, these findings were in contrast to a 2015 study that found no effect.
In this study, “myeloid” are defined in special codes, or ICD-0-3 histology types and myeloid leukemias include :. acute myeloid leukemia, chronic myeloid leukemia, myeloid leukemia and other / monocytic
Other scientists have theorized that the benefits of exercise in reducing the risk of cancer come from weight loss associated-lose fat, and they will cut your risk.
While this is certainly true of many diseases, findings of this study suggest that associations activity and physical cancer were generally independent of body mass index, or BMI, which argue against this hypothesis fat for most cancers.
The exercise, diabetes and cancer risk
For those struggling with overweight and obesity, one of the jewels that can help is to know that even a little weight loss can make a difference in terms of their risk profile, and here we are talking about their cardiovascular risk, not necessarily cancer risk.
Study Program Diabetes Prevention, or the DPP study showed that a weight loss of 7 percent with intensive behavioral interventions could reduce the risk of developing type 2 diabetes by 58 percent. The DPP study was a baseline study which showed that lifestyle can really change the development of diabetes.
When type 2 diabetes has been studied as a potential risk factor for the development of hematologic malignancies, or blood cancers, the results have not been consistent in general.
Some studies have found an association between type 2 diabetes and the risk of developing lymphoma, leukemia and myeloma. Such studies do not, however, explain how diabetes can increase the risk of a person.
For example, obesity, diet, physical activity levels and glucose lowering drugs such as metformin and other drugs are all things that tend to go with diabetes. So if a link is found with diabetes also have to examine the factors that people with diabetes fee to see what may be responsible for the increased risk.
According to research published in the May 2012 edition of “blood”, type 2 diabetes was associated with lymphoma mild to moderate increased risk of non-Hodgkin lymphoma, but not lymphoma. And when subtypes of NHL merchandise examinees, the increased risk of type 2 diabetes was present in peripheral T-cell lymphoma, but not for other subtypes of non-Hodgkin lymphoma.
In most cases, researchers do not yet know what hematologic malignancies develop cause. Certain infections such as Epstein-Barr virus, autoimmune disorders such as rheumatoid arthritis, Sjögren’s syndrome and systemic lupus erythematosus, or a positive family history may be important in the development of some of these cancers.
There is no conclusive evidence to show that type 2 diabetes is a major risk factor for the development of hematologic malignancies risk, however.
Although this study on weight loss and cancer risk were completely off base, and all its results spurious mild to moderate exercise would still strongly recommended destinations based all other known health benefits, including the overall physical condition and overall health and wellness.
Note that this article refers to the role of exercise in cancer prevention. The theme of exercise during cancer treatment is a totally different issue.
