2 Question 1

3 When people experience acid reflux, acid is pushed up from the stomach into the esophagus, causing the esophagus to get red, irritated and sometimes ulcerated. If the acid continues to reflux into the esophagus, esophagus ulcers can form.

12 Colon Cancer: Colon Cancer: Colorectal cancer, also called colon cancer or large bowel cancer, includes cancerous growths in the colon, rectum and appendix. It is the third most common form of cancer and the second leading cause of cancer-related death in the Western world. Colorectal cancer causes 655,000 deaths worldwide per year, including about 16,000 in the UK, where it is the second most common site (after lung) to cause cancer death.[1] Many colorectal cancers are thought to arise from adenomatous polyps in the colon. These mushroom-like growths are usually benign, but some may develop into cancer over time. The majority of the time, the diagnosis of localized colon cancer is through colonoscopy. Therapy is usually through surgery, which in many cases is followed by chemotherapy.

19 A strain is a tear or stretch of a muscle or tendon. People commmonly call such an injury a "pulled" muscle. Your hamstring muscle group is in the back of your thigh, and allows you to bend your knee. It is made up of three large muscles: the biceps, semimembranosus, and semitendinosus.
