My friend and I both had abnormal developments in our body at the same time in high school - when the doctors removed my abnormal growth they used a term which I think suggests it was cancerous at the time it was identified by the doctors but went into spontaneous remission by the time the doctors had removed it from the body. My friend's abnormal growth could not be removed due to its dangerous location so she had to get radiation treatments for it. Around the time I and my friend had cancer scares - my mother was diagnosed with kidney disease and it was viewed as cancerous. Also a guy from my church got the same cancer as his dad a year after his dad died from cancer. I've also heard of dogs dying from cancer when their owners get cancer before them. I watched a Ted Talks on t. v. saying that in some rare conditions - cancer can be passed on from one person to another. I also heard you can reduce your cancer risk by half with meditation.
