Q&A: Options for colon cancer screening

  The human colon. Colorectal cancer occurs in the colon or rectum when abnormal growths, called polyps, form and become cancerous over time.

 

Question: Is the fecal smear test my best colorectal-cancer-screening option?

 

  Answer: Being screened for colorectal cancer is crucial. Of cancers that affect both men and women, colorectal cancer (CRC) is the second- leading cancer killer in the United States, according to the Centers for Disease Control and Prevention.

  CRC occurs in the colon or rectum when abnormal growths, called polyps, form and become cancerous over time.

 

Symptoms of CRC can include weight loss, abdominal pain, rectal bleeding, and anemia.

 

  However, the beginning stages of CRC may not show symptoms. Therefore, being screened is the best preventive method.

    There are several screening options available, including:

• Colonoscopy.
• Fecal immunochemical test (FIT).
• Flexible sigmoidoscopy with FIT.

 

  The “gold standard” of colon screening is a colonoscopy. Patients prepare for a colonoscopy by drinking special “prep” liquids to clean the bowels. During the procedure, patients are sedated as a flexible colonoscope is inserted into the rectum. A gastroenterologist will look for polyps and other abnormalities. This screening test should be performed every 10 years after the age of 50, according to the American Cancer Society.

  FIT is a stool-based test that can be done at your home. A tiny amount of stool is placed into a vial, which you mail to a laboratory for analysis. There is no preparation needed for this test. If lab results show a positive result for abnormalities, the next step is to schedule a colonoscopy. FIT is good for early detection and should be performed every year.

  Flexible sigmoidoscopy with FIT is an alternative to both the colonoscopy and FIT tests. Flexible sigmoidoscope does not require a “prep” drink, but the patient does require several enemas to clean out the lower part of the colon. There is also no need for IV sedation, but you can opt to have it. For this test, a flexible tube is placed into the rectum and examines only the lower colon. This is similar to a colonoscopy, but it doesn’t scan the entire colon. If the lab results come back positive, schedule a colonoscopy. This test should be performed every five years along with a FIT test every year.

  Each colorectal-screening test has its advantages and disadvantages. Talk to your doctor to decide which test is the right choice for you.

 The crazy cost of an emergency room visit is getting out of hand and financial range for most people.  Even if you have a decent healthcare program you are likely to spend $120 to $265 just to get seen. Heaven forbid if you have to be admitted as an inpatient.  But what about the other essentials you'll need not to mention adding in the cost of food and other necessities. So instead of hitting the panic button why not be prepared for those emergencies with the knowledge that will have you prepared.  

There are several items in your very home right now that could save you a trip to the hospital. Find out what you need to store right now just in case. The more knowledge you have about these things the less stress you'll have whenever these events present themselves.  The Home Doctor is something that you absolutely need around your house or at least someplace you can easily get to.

 It is comforting to know that if you are within an hour's drive, you can reach the sliding doors of medical help. But what if some unforeseen small disaster happened that you could take care of yourself if you were only prepared with the right information and knowledge. And what if all the things you needed were right in your kitchen.  Let's say it's Friday night around 12;30 and the nearest hospital is totally overwhelmed with patients this presently happened to a family member at their local hospital, in which they spent a total of 15 hours waiting and STILL was never seen!  Feeling helplessly frustrated and pissed off they when to a different facility the next day.  All this is to say, that some basic knowledge of a few natural ingredients that you have around the house will resolve an issue or give you time until the issue is dealt with.

  Most people in South Florida remember Hurricane Katrina and what a disaster that was, but nothing compared to the medical horrors and hardships in Venezuela. I am not a doomsday prepper, but having certain common household supplies on hand can increase your preparedness and allow you to get more advanced help.

  As a side note, the Combat Support Hospital Unit I was attached to spent almost a year isolated in the desert of Iraq with the 120-degree mid-day temperatures, we needed to have the most important supplies available at any given moment. and it kept us going until supplies arrived. Knowing that we were prepared long before the action started and with all the supplies we needed gave us a sense of relief.  After 47 years in the medical field, Just Saying!
