just remembered i have regular liver function tests as the chemo has effected my liver function . and my platelettes are still down and my vit d is very low and i am 4 years since diagnosis. as to the coughing and blood if it was a Beeeeeeeg cough you could of just burst a small blood vessel in the throat, so could be nothing.
i would still check with your oncologista or the chemo nurses. and just because you have constipation a a bit of blood doesnt mean cancer my husband has 2 yearly colonoscopy as he had similar probs but just polyps.
