When someone is diagnosed with cancer, the challenges that come with fighting the disease can ripple through their whole family. Even for those who aren't close enough to face the disease alongside them, it can be hard to see someone they love in such clear suffering.
What doesn't help is how volatile and unpredictable cancer can sometimes be. All signs can indicate a full recovery, only for a survivor to discover that the disease has suddenly returned and they have to go through it all over again.
Sadly, this experience is well known to the Chapman family.
