Why don't old people get cured? Aren't there cures for most types of cancer?
Not really. There's no "cure" for any cancer, as such.
There are a number of different treatments that can be used in the hopes of eliminating them, but there is no guarantee.
Some are easy to get rid of, due to the position of them within the body, whereas others are much more difficult.
Then you have to take into consideration how long the cancer has been growing. With most cancers, particularly internal ones which can't be seen (or sometimes even felt) you can have them growing for months or even years. And through all that time it can spread to any other part of the body. If it gets to the bone marrow in particular then there is very little to be done. At which point no amount of treatment will get rid of it. Just slow it down at most.
And bear in mind how terrible cancer treatments are. You're often pumped full of many many chemicals that are essentially designed to kill cells, or exposed to radiation. They make you feel unimaginably sick and weak, and your immune system gets really poor.
And then after all that, if the cancer is gone, whether it's gone into recession or it's been surgically removed, it can come back at any time.
All cancers are horrible diseases. And if you get one, it's sadly just pot-luck as to whether it's in a 'good' place and whether it's found early enough for action.
I'm really sorry for your loss, OP.
I lost my grandfather a few years back to lung cancer, and then my Nan to stomach cancer last year, which was very sudden.
Hopefully with time though you'll be able to think back in happiness, rather than sadness.
