Lack of exercise and being overweight increase the risk of cancer. This was announced by the expert at the National Center for Tumor Diseases (NCT) during a congress in Heidelberg.
Countless researchers are looking for the possible causes of the various cancers. Now the director of preventive oncology at the National Center for Tumor Diseases (NCT) in Heidelberg, Dr. Cornelia Ulrich, at a congress rather casually informed that overweight and lack of exercise are an essential factor in the growing spread of cancer.
Direct connection to numerous cancers In the opinion of the expert, 20 to 25 percent of cancers in Germany are caused or at least favored by lack of exercise and being overweight. In the United States, experts estimate that up to 40 percent of cancers are related to sedentary lifestyle and obesity. According to Dr. Cornelia Ulrich is particularly large, especially with the common types of cancer such as colon and breast cancer. For example, lack of exercise plays a not negligible role in colorectal cancer. Liver cancer, on the other hand, is directly favored by being overweight through the development of a fatty liver. According to the specialist, esophageal and kidney cancer are also related to obesity. In addition, both obesity and a lack of exercise significantly increase the risk of breast cancer for women after the menopause, Dr. Ulrich continued on the sidelines of the Heidelberg Congress.
More and more cancer patients due to obesity So far, the negative effects of obesity and lack of exercise on the cardiovascular system have mostly been in the foreground, but the Director of Preventive Oncology at the NCT is now leading the discussion in the direction of the connection with the various cancers. For example, due to the growing number of overweight people, individual forms of cancer such as esophageal cancer, which until a few decades ago were a rather rare disease, have increased particularly sharply, explained Dr. Ulrich. According to the expert, the USA is particularly affected, since the proportion of overweight people in the total population is particularly high here. While smoking has a significant share in the growing number of cancers in Germany, Dr. According to Ulrich, obesity in the United States is the determining factor in terms of the increasing number of cancer patients.
Maintaining a minimum level of physical activity There is usually a direct connection between a lack of exercise and being overweight, with the increased physical activity gradually reducing the excess weight. Therefore, with appropriate exercise training, you can make a significant contribution to effective cancer prevention. But even in patients who already have cancer, Dr. recommends Ulrich a certain level of physical activity. Because recently the American College of Sports Medicine also recommended that cancer patients should exercise. According to Dr. Cornelia Ulrich will also take into account the results of ongoing studies in the future that deal with whether other physical mechanisms, such as the repair of DNA, can be positively influenced by sport.
Exercise as a prevention and treatment for cancer With the recommendation of the panel of experts from the American College of Sports Medicine, which is based on numerous medical studies, a long-standing principle in cancer medicine is finally obsolete. A cancer does not rule out sports, as was previously the usual medical recommendation, but a certain level of physical activity should always be maintained and can have a beneficial effect on survival after cancer therapy, emphasized Dr. In general, most cancer patients are able to complete a sports program that is tailored to them and that can have a beneficial effect on the healing process. For example, the NCT, together with the German Cancer Research Center, is currently investigating in a study what success targeted exercise can bring as therapy against exhaustion. However, the training must be explicitly adapted to the patient's clinical picture in order to exclude negative effects, for example in metastases in the bones or in breast cancer patients with edema in the limbs.
