to prevent cancer mantain a healthy and balanced lifestyle, and also environmental factors. if you live a stressful life, or smoke cigarettes of course that will increase your chance of getting cancer. unfortunatley sometimes you have a stressful job or a situation that comes up that causes you to stress for months or years. knew a guy who the feds went after hard for bad business practices, and he had a 2 year court case which dragged on. by the time the case was over the poor schmuck had died from cancer. the stress took a toll on him, probably barely slept those 2 years, worried about his family.. etc. he fought the feds for 2 years in court and ended up dead. had he just ran his business ethically he would probably still be alive today
