<s>[INST] Yes please, I m pretty sure I suffer from depression , when I feel down I drink to excess, although I am a reasonably heavy drinker anyway. Also I do take drugs casually, mostly cocaine but most weekends. Anyway I ve had a problem with going to the toilet for a number two. I seem to need to go very regularly, and often there is blood , lots of blood, not in the stool but seemingly afterwards. And if I sit there it will just drip for ages. I ve just split up with my girlfriend and am drinking to massive excess, I ve not eaten for 4 days and this problem is worse than ever. Im pretty sure it s alcohol related and I know I need to go to the doctor, but can you tell me what you think it is? I m scared, both sets of grandparents died from cancer , also my father. [/INST] I would have liked to know your age and what cancer did your father and grandparents die from. Certain types of cancers of the colon and rectum do have a hereditary component and the risk is further compounded by alcohol abuse and poor dietary habits. The good news is that the type of bleeding you have described is most commonly due to hemorrhoids particularly in the young age group. However, there is only one way to find out whether you have cancer or not and that is to show it a surgeon or cancer surgeon who will examine your anus and rectum in the old and remove your dilemma. </s>
