Answer:
weight loss without trying to lose weight.
Explanation:
Colorectal cancer is a malignant tumor that develops in the large intestine, ie the colon or its final portion, the rectum. Because cancers have a significant genetic factor, it is common for Sophia to be concerned about developing this cancer, since her father had it, so ideally Sophia is mindful of changes to her body as a form of prevention. The main form of prevention of colorectal cancer is its screening by exams such as colonoscopies, aiming at the detection and removal of polyps before degenerating into cancer.
A specific symptom of this cancer is weight loss, without the individual planning to lose weight. So if Sophia begins to lose weight without her doing anything to do so, she should immediately tell her doctor to perform the necessary procedures if she has cancer.
