Colon Cancer


Colorectal cancer is the number 2 cancer killer in the United States, yet it is one of the most preventable types of cancer. Colorectal cancer is often curable when detected early.

Risk Factors

  • Lifetime risk of colorectal cancer is roughly equal in men and women.
  • Colorectal cancer is most common after age
    50, but it can strike at younger ages. The risk of developing colorectal cancer increases with age.

Most early colorectal cancers produce no symptoms.
This is why screening for colorectal cancer is so important. Some possible symptoms, listed below, do not always indicate the presence of colorectal cancer, but should prompt a visit with your physician and a check-up:
      • New onset of abdominal pain
      • Blood in or on the stool
      • A change in stool caliber or shape
      • A change in typical bowel habits, constipation, diarrhea

Colonoscopy is a procedure which enables a physician (usually a gastroenterologist) to directly image and examine the entire colon. It is effective in the diagnosis and/or evaluation of various GI disorders (e.g. colon polyps, colon cancer, diverticulosis, inflammatory bowel disease, bleeding, change in bowel habits, abdominal pain, obstruction and abnormal x-rays or CT scans) as well as in providing therapy (for example, removal of polyps or control of bleeding). It is also used for screening for colon cancer.

Esophageal Cancer

Who gets Esophageal Cancer? Studies show that esophageal cancer is more commonly diagnosed in people over the age of 55 years. Men are affected twice as commonly as women. Squamous cell esophageal cancer is more common in African Americans than Caucasians. On the other hand, adenocarcinoma appears to be more common in middle-aged Caucasian men.

The exact cause is unknown; however there are well-recognized risk factors. In the US, alcohol, smoking and obesity are the major risk factors. Stopping drinking and smoking may reduce the chance of getting esophageal cancer as well as other types of cancers. Sometimes adenocarcinoma of the esophagus runs in families.

The risk of cancer of the esophagus is also increased by irritation of the lining of the esophagus. In patients with acid reflux, where contents from the stomach back up into the esophagus, the cells that line the esophagus can change and begin to resemble the cells of the intestine. This condition is knows as Barrett's esophagus. Those with Barrett's esophagus have a higher risk of developing esophageal cancer.

Less common causes of irritation can also increase the chance of developing esophageal cancer. For example, people who have swallowed caustic substances like lye can have damage to the esophagus that increases the risk of developing esophageal cancer. More Info
