mikes Posted October 19, 2005 Share Posted October 19, 2005 Many believe that that various types of cancer are really a malfunction of the mechanisms that regulate a person's DNA. A person's DNA can be determined from body fluids, tissue, etc. My question is whether a malignant tumor still carries the host's DNA or whether it is foriegn to the person. Another way of asking this is can a DNA sample from a tumor identify this person just like DNA from another part of the person's body?

Donna G Posted October 19, 2005 Share Posted October 19, 2005 Perhaps the DNA has changed! Had not thought about it in that way. I had thought perhaps some people have it in their genes that they would be more suseptable to getting a cancer.

rvillella Posted October 19, 2005 Share Posted October 19, 2005 I would think that it is only a portion of the DNA that changes. Since the strands contain so much information one little maladjustment in the part of the sequence would cause the cancer. I'm currently in a blind study to try and determine markers in the DNA for Cancer, to try nd help in early detection. Ralph Quote Link to comment Share on other sites More sharing options...
