My Grandmother was 69 yo when she had open heart surgery. Following that ordeal, we found out that she had uterine cancer. So, she had a TAH/BSO. It was all within months of each other. She was in the hospital more than she was outside living. It was such a hard time for everyone.
The gyn who was working on her case left the decision up to her about her treatment plan. She was never suffering from dementia or any other mental disorders, so we all knew she was making the best decisions for herself.
As for the chemo and radiation. She decided to go through the radiation first (4 treatments). Then the chemo treatments followed up. Well, she had one chemo treatment and that was it. It was too much for her and her little body to take. The radiation really was tough too, but she was a tough ol' bird. The treatments were tough and brutal. She ended up having to have cut-downs because her veins would roll or break from all the iv's and blood being drawn. At one point she even mentioned to us that this was not worth it. The pain alone was just overwhelming.
My Grandmother died from heart disease when she was 89 yo. It was really a blessing.
I think any sort of cancer treatment is hard. Hard on your family, friends, not to mention yourself and your body. I think that only that person can really make a decision about enduring treatment of any kind. Sometimes the best treatment is none at all. Nobody can make the decision for you. It has to be your own.
Please let me know how things work out. I will be including you in my prayers.
