It takes a long time for the tiny coral polyps to create an entire reef. Coral formations grow an average of 1 to 8 inches per year. While ancestors of today's coral date back 240 million years, today's reefs began growing more than 50 million years ago, although most reefs are about 5,000 to 10,000 years old.hile ancestors of today's coral date back 240 million years, today's reefs began growing more than 50 million years ago, although most reefs are about 5,000 to 10,000 years old.
Esophageal motility disorder. An esophageal motility disorder is any medical disorder causing difficulty in swallowing, regurgitation of food and a spasm-type pain which can be brought on by an allergic reaction to certain foods. The most prominent one is dysphagia.
âBenignâ means esophageal cancer isnât causing the condition. Benign esophageal stricture typically occurs when stomach acid and other irritants damage the lining of the esophagus over time. This leads to inflammation (esophagitis) and scar tissue, which causes the esophagus to narrow. Although benign esophageal stricture isnât a sign of cancer, the condition can cause several problems. Narrowing of the esophagus may make it difficult to swallow. This increases the risk of choking.
