Thank you for your love @outlander
We all have cancer cells. The Human body is made up of more than 50 trillion cells! those cells are constantly dividing and multiplying and as a result there will always be some cancer cells. Our bodies have the ability to get rid of them! Our immune system is one defense and another is our body's ability to resist blood vessels from growing into and feeding them. Your body is healing you, without you even knowing it. You can 'do' something while your waiting for the next test. You can eat healthily, do regular excercise, focus on sleeping well and think positive. Thinking positively is a very strong medicine - it helps your body heal in every way.
I don't blame you for being scared, I absolutely understand.
In fighting your fear you will fight all of the bad within you and without.
Maybe you could visualize the bad as a darkness and the good as light. Everytime you eat something healthy, sleep, excercise, smile, laugh, help someone, do good, your light will shine brighter and the darkness will fade.
