The "Good" Cancer

The Doctors told me because I have Thyroid Cancer that I have a "good cancer."
I never knew there was a better type of cancer to have.
They said it is very treatable so it's the best to have.
Why do I have to have any type of cancer?
It caused just as much pain.
It made myself and loved ones worry just as much.
I might lose my hair like other people with cancer.
I still have to take medications everyday to keep myself alive.
I go to bed every night praying I'll wake up the next day.
My parents still cry and worry that they will outlive their daughter.
I still have to see doctors all the time.
I don't get to see my friends as much because I get sick a lot.
I look tired all the time.
I don't understand how this is a "good" cancer.
I've been beating my cancer for two years now.
Like other cancers, it can come back when it wants to.
I still have to get cancer scans & tensions rise out of worry.
I have to stop my medication and be put in isolation.
I spent two summers of my life doing cancer treatments.
I had to drop out of school for 9 months.
Now I'm behind my class and getting back on my feet.
Like people with other cancers, I always end up thinking I might not survive it.
I'm a 21 year old cancer patient.
I get sick easier than most my age.
I don't get to go out as much as I like because I'm tired a lot.
Please somebody tell me how this is a "good" cancer.
Most associate the word cancer with death.
How is this "good"?
I'm not going to give up though.
I refuse to let my parents bury me.
I don't want to leave my friends.
I want to go out with them and be the crazy bubbly girl I used to be.
I refuse to stop dating.
I refuse to stop planning my future.
I want to get married and have my own children.
Yes, I've become stronger from all of this.
However, I still don't see how this is a "good" cancer.
