can the cecum be seen during a colonoscopy? or is it through a sigmoidoscopy? can cancer of the cecum be detected through radiology tests like ct/mri?

Question

I am obese, and had CT, MRI, Colonoscopy, etc. tests. Doc says no anal cancer.I have hemmorhoids.I keep reading online docs can misdiagnose A.C. true?

Answer 1

Yes-No-Maybe: Colonoscopy evaluates the entire large intestine, from cecum to rectum. Flexible sigmoidoscopy only goes as far as the left side of the colon, nowhere near the cecum. Routine ct scanning may identify a (large) cecal tumor but is much less sensitive than a colonoscopy; ct colonography is almost as sensitive as a colonoscopy, but is less desirable than colonoscopy since a biopsy cannot be done.

Answer 2

Yes No Maybe: The cecum is the first part of the colon and is in your right lower quadrant and should be visualized during a proper colonoscopy. It is not visible with a sigmoidoscopy. Ct/mri may detect a cecal cancer if it is large enough, however a normal scan should not negate the need for a colonoscopy if the concern for cecal cancer exists.

Answer 3

Virtual Colonoscopy : Ileocecal valve ; cecum are seen during colonoscopy. Sigmoidoscopy doesn't reach the cecum. Virtual colonoscopy using ct or MRI is an alternative colon cancer screening method that can detect cecal cancer. It's less invasive and has fewer complications compared to endoscopic colonoscopy, but occasionally a follow up traditional colonoscopy to remove the polyp or perform a biopsy is needed.

Answer 4

Yes and no: The cecum can be seen on colonoscopy as long as the scope can be passed all the way through the colon. In a sigmoidoscopy, on the colon that is near the rectum is seen. The scope involves a limited part of the colon. CT and MRI may be able to detect more advanced tumors in the cecum unless CT colonography is performed. Small tumors often cannot be seen on conventional CT or MRI.

Answer 5

Very Important: There is no link between stress and development of breast cancer. Stress can adversely affect a womans' ability to undergo complex and lengthy breast cancer treatment- this in turn can lead to inferior results. Patients without psychosocial support for stress can develop problems such as ptsd, strained spousal relationships, sexual problems, etc.

Answer 6

Stress can cause it.: Very recently there was a study that identified stress as an independent cause of a type of breast cancer-called triple negativethis type is very aggressive even at a small size. It means that this type does not have hormone receptors for estrogen and Progesterone also is negative for her2 receptors. This type accounts for about 15% of all breast cancer. We don't have targeted tx yet.

Answer 7

Doesn't help: There is not clear evidence, but decreasing your stress has to be good thing.

Answer 8

Stress and cancer: No strong evidence that stress causes any cancer. However , those who attempt to manage their stress with risky behaviors such as smoking or drinking alcohol- can increase the risk to have cancer related to their behavior. Also, from experimental studies- it's suggested that stress can affect a tumor’s ability to grow and spread. Emotional and social support can help cope with psychological stress.

Answer 9

Probably not: True lung infections caused by candida are almost unheard of. People with severely suppressed bone marrow function can get systemic candida infections, but most such people are hospitalized in bone marrow or other organ transplant units or similarly immunosuppressed (but rarely cancer patients receiving outpatient chemo for example). "candida pneumonia" is almost unheard of.

Answer 10

Cancer itself: Does not pre-dispose to opportunistic infections like candida, but treatment can lower host defenses, include steroids, and these may increase risk. Awareness and early diagnosis is the key, not prophylactic treatment.

Answer 11

No: Having prostate cancer does not make a man more likely to become septic or become infected.

Answer 12

No: A bacterial infection can become septic (get into the blood stream) whether you have prostate cancer or not.

Answer 13

Yes: Yes. Patient with chronic hepatitis b will require screening for liver cancer at some point. Current recommendations are starting at age 20 for african born individuals and age 40 for Asian born individuals. However, patients prior to these ages can develop cancer. High HBV viral loads are associated with increased risk of cancer. As always develop a screening plan with your liver doctor.

Answer 14

Yes: Liver cancer is the most common cancer in asia because almost 25% of the Asian population has hepatitis b. Many patients acquire hepatitis b from their mothers and can develop liver cancer as early as mid 20s.

Answer 15

Yes: Unlike most viral hepatitides, hepatitis b is associated with liver cancer regardless of the presence of cirrhosis. Therefore, blood test (i.e. Alpha-fetoprotein) and imaging study (i.E abdominal ultrasound) are recommended every 6 months beginning at the age of 40.

Answer 16

Theories: Of slow bowel activity, build up of bad bacteria creating toxins or toxic environment. And healthy intestinal bacteria with higher fiber diet may cause less colon wall mucosal irritation and less risks for cancer. Also theories of low fat diet and increased exercise lowering colon cancer risks.
