Hi. My dad was diagnosed with a brain tumour in May and it has devastated me and I am finding it hard to deal with. Hw was operated on but they couldn't get all of the tumour out and was told it was grade 4. He had 6 weeks of radiotherapy and had chemotherapy tablets too. He was looking and feeling great throughout the treatment apart from feeling really tired now and again. 3 weeks after his treatment he has started feeling sick alot, has no appetite at all and under his eyes are swollen. I hate seeing him like this as he was always on the go and and ate everything that was put in front of him as well as having a sweet tooth! Why has he started feeling like this now? He isn't allowed to drive either now so this is getting to him too as he was always in the car and helping others out but now he is really fed up sitting around the house. I am so worried, my dad is my hero and i can't bear to think.of losing him.
