Would diagnostic laparoscopy find ovarian cancer if there was any? I've had one, and ultrasounds and a colonoscopy but no cause for bloating found

Bloating is often caused by excessive fiber along with inadequate fluids and all of the exams you had would all be negative. Try modifying your diet, cut out caffeine and drink 80-100 oz of fluids per day for 10-15 days. Simethicone and charcoal tablets may also help as will probiotics. ...Read more

Why are colonoscopy performed years apart? Shouldn't they be more often? Doesn't cancer grow fast?

Why are colonoscopy performed years apart? Shouldn't they be more often? Doesn't cancer grow fast?

Good question: Most colon cancer differs from other cancers in that it tends to progress in a very predictable pattern beginning as polyps that can sometimes form cancer. This process takes many years. For example, it can take 5 or more years for a polyp to reach 1 cm and then another 5 or more yrs for the 1 cm polyp to become cancer. This is why the standard recommendation is to have a colonoscopy every 10 yrs. ...Read more
