Good morning, I don't know where to begin. As the title states, i am afraid i may have colon cancer. I experienced a rapid shift of symptoms within 5 days. I had blood in my stool (mixed in and this was the initial symptom). I was just fine weeks, months and even years prior and had a steady weight of 173. I checked my weight and i was at 173 still. The next day, 172, then later that day 171, 170, 169 and continued to drop in weight. My stools changed from solid to ribbon to diarrhea. My anxiety and stress are through the rough and i just feel like a completely different person today. I don't understand how my life can change and these symptoms come on so rapidly out of nowhere within 5 days. I had blood work done and everything looked fine except wbc, hematocrit and ca++. I'm lost and confused, so i decided to try this keto diet/fast. Any tips or advice would be helpful.
