Hey Tracey
Sorry you have to have chemo, but it is not as bad as the visions you have in your head. You will handle it fine, its not gonna be fun, but I promise you with the drugs they have available for the side effects it is doable.
The heart test is a standard proceedure so they can monitor the effects of chemo on your heart. Because you are young they need to have baseline, so they can make sure your heart will last you for a LONG time. Have you had a bone scan? well it is very similar to that, I cant even remember if they have to inject contrast via a canula, then you lay on the bed and they will check some readings and thats it.
And the port is a simple operation some people have it whilst under anethestic and some only a local. Your veins will thank you for it.
Anyway, feel free to come and have a whinge whenever you want. Chin to the wind. You will handle it fine.
