Isn't it awful how a person goes down hill so fast when they're diagnosed with cancer? [I Hate Cancer]

My father in law had a biopsy of a lump in his stomach last Monday, he's already been told its stage 3 cancer and about his treatment plan, however, he got an allergic reaction to whatever dye the used and also an infection, he's developed a cough which might be from the lung cancer, he was taken to hospital in ambulance on Saturday night as he had a high temperature and they then discovered that he has an irregular heart beat also, his temperature still isn't coming down and his cough is getting worse

2 weeks ago he was walking in the mountains for 6 hours a day.. 😱
