As I understand it there is three types of testing done on cancers.
1. Genetic test to determine whether you have certain genes that increase the possibility of cancer in you or your relatives. This can be done on a healthy person with family cancer history too.
2. Genomic testing is performed when you already have cancer and they look into your cancer's DNA to see if the cancer is a certain type. (Kras positive, Kras wild etc.) This is important because certain type of colon cancers will not react to certain chemo drugs.
3. Chemo sensitivity test is done after a small piece of the cancer is removed. They want this sample within 24 hours after removal preserved a certain way. They will keep these cells alive and test different chemo dugs or combination of different drugs and see how the cancer cells react, therefore finding the most effective drugs for the particular cancer.
I had the first two done and having the last one performed after my cancer was removed last week.
I believe the last one is very important in practice and if interested go to the www.rationaltherapeutics.com.
Please correct or add your valuable knowledge to this.
