Colon Cancer: What is a Colonoscopy?

Colonoscopy is one of the least invasive endoscopic investigations of the large colon and the distal section of the small bowel with a CCD camera or a fiber optic camera on a tube that is flexible enough to be inserted through the anus. It may give a visual diagnosis (for example ulceration, polyps) and gives the opportunity for biopsy or the removal of any suspected lesions. Before a colonoscopy, patients have to under colonoscopy prep or colonoscopy preparation. Virtual colonoscopy, which makes use of 2 dimensional and 3 dimensional images reconstructed using CT scans or from MR scans, is also an option, as an entirely non-invasive test, although it is not regarded as standard and still requires investigation in relation to its diagnostic capabilities. In addition to this, virtual colonoscopy restricts therapeutic maneuvers including the removal of polyp and/or tumors or biopsy nor visualisation of any lesions smaller in size than 5 millimeters. Once detected, a standard colonoscopy would be performed on a growth of polyp. Colonoscopy can be carried out to remove polyps that are smaller than one millimeter. Once a polyp is removed, further study can be carried out on it using a microscope. This will help to determine wether or not if the polyp is precancerous. Colonoscopy has some similaries to sigmoidoscopy, but they are no the same. The difference is that the procedures are carried out on the same parts of the colon. However, Sigmoidsocopy only allows for the viewing of the final 2 feet of the colon, whilst colonoscopy allows for the examination of the whole colon. This is often 4 to 5 feet in length.

How do I live my life for myself?

I am 32 years old and I feel like I am always living my life for my parents and everyone else. I have two children and am raising them by myself. I was diagnosed with cancer 4 years ago and my family got in a huge fight of where I would go for medical attention. etc to the point where I was being pulled in every direction and no-one stopped to ask what I wanted. It really tore up my family, it's not what it used to be. My children are being raised Catholic (I was also) and as much as I love my faith and rely on it alot I feel like if I don't bring themto church every Sunday (they are in CCD) my dad asks why (yet he doesn't go most of the time and he never questions my sister or brother). Now, I am seeing a great guy and my mom is so worried about me that something may happen to me that I had to call her when I got out of the date to let her know I was okay. I feel like Iam under a microscope and I love my parents but feel like they have control over my life, how do I get it back?

look please your life with that great guy
he will support you
Does he knows about your health?
test him for a while but if he is really nice rent a house with him
live your life together with the kids and left your parents alone
if they dont understand isnt your mistake
live your life NOW
