My sister has just been told that she has a 10 cm tumour in her pelvic area, she had her bowel rupture in Dec 2013 and since then has been having chmotherapy and we thought was getting over it all, she had another tumour removed from her liver and all seemed clear recently she had a scan and the tumour was revealed, it looks as if it must be aggressive to have grown so big without being noticed before. Now she has been told she cannot have it removed and they are going to look into some more chemotherapy. How long is it likely to be before she dies?
