<s>[INST] i am bleeding from my anus for a few weeks now its always off and on but i read on a site tht if it doesnt cause pain and its a dark red and in clots i may have cancer. what is the easiest way to find out if i do if i dont have money to go see a doctor? [/INST] Thanks for your question on Chat Doctor. I can understand your situation and problem. Painless, bright red bleeding from anus is mostly due to piles (hemorrhoids) and anal canal cancer. Best way for diagnosis is locale site examination of anus. If on local examination dilated veins are seen than it is piles. But if nodule or mass or ulceration are seen than possibility of anal canal cancer is more. For all these you need to consult doctor and get done clinical examination of your anus. You may require bronchoscopic examination also. So consult doctor and discuss all these. Hope I have solved your query. Wish you good health. Thanks. </s>
