My sister was diagnosed with small cell lung cancer back in March of last year! They treated with chemotherapy and radiation treatments. At the end of October last year she was given the all clear of cancer. Wow we thought this is fantastic. Yeah right! Short lived! She has now been diagnosed with an aggressive frontal malignant brain tumour. They thought she would only have between 2 to 4 weeks to live as of the 30th December last year, she has been having radiation to the brain for some weeks now and the last dose they can give her is Thursday of this week. She talks to you, walks about 30metres a day. eats and eats all day, but how long do you really think she has, as the doctors here just do not have a clue?
