### output:

Hi, loose stool may be due to infection or hypersecretion so detailed history required. Black stool cant be due to rectal or anal cancer. Black tarry stool should be due to upper G-I bleed and that can be a cause of collapse. So stool exam to be done, if necessary blood transfusion will be needed. Anyway anorectal cancer can be treated by chemo radiotherapy first, if not metastatic disease. Then surgery may be tried. First go for conservative management at a good hospital then think about definitive management.
