The survival in prostate cancer depends on the patient’s body weight. Overweight at diagnosis is associated with an increased risk of death from this disease.
A new prognostic factor reported by the medical clinic Kaiser Permanente. The study reviewed the records of 750 patients who had undergone radical prostatectomy surgery due to prostate malignant neoplasm. The analysis showed that the chance to survive for two years after surgery was 1.5 times higher in patients without excess weight and obesity. Furthermore, the degree of aggressiveness of the tumor is also directly dependent on the body weight index.
Overweight in adolescence also increases the risk of cancer of the esophagus in the future twice.
Israeli scientists studied data on the health of one million 17-year-old boys who passed a medical examination for military service. The experts compared the body weight index of study participants with the data base of the National Cancer Registry to determine which of volunteers later appears to get dangerous disease.
The analysis showed that the weight and the social status of a person under 17 years affect the risk of developing esophageal cancer in later life. For example, overweight raised the risk by 2.1 times and low socio-economic status – by 2.2 times. This is due to characteristics of food (in particular, the consumption of salt) and smoking which are factors of gastric cancer.
