18 year old male, asian, no family history of colon cancer or any other cancer. Paranoid by nature. Please do bear with me here.
One month ago: I started noticing blood on the tissue after going to the toilet. I visited the doctor, who upon inspection, found two bleeding hemorrhoids. After applying cream, the bleeding stopped after I visited the doctor and has not come back since.
One week ago: Next came the diarrhea and some slight cramping. The diarrhea/cramping lasted for four to five days. As these were also symptoms of colon cancer, I started becoming paranoid. Another visit to the doctor and he prescribed me more medication. After taking the medication, these symptoms were immediately cured and I no longer have diarrhea or cramps.
Right now: I have been experiencing some quite severe fatigue for the past three days, on and off. I'm now really concerned, as fatigue is also another sign of colon cancer. In the past month I have now exhibited three symptoms of colon cancer...
My question is: is what I described above worthy of concern? Should the fact that medication cured my symptoms mean it's something less serious, or am I wrong about that? After all, three symptoms within a small time frame is a very worrying sign. Please, tell me what you think? Is it likely I have colon cancer?
