I had antral gastritis,piles grade 2 years ago. I had then done colonoscopy and endoscopy, sigmoidoscopy,ct scan etc tests. Ct scan report and colonoscopy reportbwas normal then. But since 8 months i have a vomiting tendency,bloody stool even if the stool is soft blood will surely come out always. And most importantly i am feeling a heaviness and feeling like something is in my right side of my belly ,even when i sit down bending i am feeling uncomfortable,moreover i have papules in my face from.last 1month.it is like pimpkes but more than that it looks like a swollen bump.is it due to cancer? As all symptoms of mine are similar to a colon cancer or stonach cancer patient (according to google), Please guide me doctor...is it cancer?what do you think?
