I am 16 years old. i'm very afraid i may have colorectal cancer or ovarian cancer. my symptoms are very similar. is it too late to treat either?

Let me check Lotto!: I have more of a chance of winning the lottery (and I didn't buy a ticket) than you have of having these cancers at age 16. These are both cancers that develop after decades of improper care and/ or diet (esp colorectal). My bigger concern for you is why you think you have these. What symptoms are you dealing with, and then we can suggest what may be the cause and who to see with your concerns.

Probably no cancer: The two malignancies you are concerned about rarely occur before age 30. Ovarian tumors at your age grow very large and most often benign. Colon cancer unless genetically inherited rately appears before 30. If anxious, have an abdominal scan.

Cancer: There are many things that cause diarrhea, pain, and bloating. Particularly at your age, cancer would not be a top consideration, it would be pretty far down on the list. Don't speculate on the worst possible case scenario. See your doctor, he/she will help sort it out.
