Why can breast tumors be imaged using a scanner but colon or pancreatic cancer cannot?

See below. This is a difficult question to answer in short format. Mammogram and breast ultrasound can see breast tumors. Tumors of the colon are located inside the organ and are best seen by colonoscopy. Pancreas tumors or colon tumors can be seen by ct scan, but only when they become fairly large.
Virtual colonoscopy. Pancreatic tumors can be visualized using ct scan or MRI with pancreatic protocol and sometimes by ultrasound. Breast tumors can be visualized using mammogram, ultrasound and breast mri. Colon cancers can be visualized colonoscopy or air contrast barium enema. More recently colon cancers have been visualized using ct technology such as virtual colonoscopy although it is not yet considered standard.

Why are breast tumors imaged with a scanner but colon or pancreatic cancer cannot?

All diagnostic. Tests have limitations, depending on the size and anatomical location of the tumor. In the breast, it is relatively easy because it is an external organ. Pancreas is an organ located deep behind the abdomen in the retroperitoneum, so it is more difficult to image. Colon cancer can be imaged these days with ct virtual colonoscopy, but presence of stool can make it difficult to image. Read more...

Mothers mom had pancreatic cancer at 72, dad had colon at 87, she had had lobular breast cancer at 54. I've had brca testing- negative. Am I at risk?

Doubt. With the negative BRCA tests, your risk of these is much lower. They may identify other genetic tumor markers for these as time goes on. Remember, the majority of colon cancer is found in persons without a family history for it. Read more...
Some risk. There is some risk even though you don't have the BRCA gene mutation. If your own parents, instead of your grandparents, had these diseases your risk would be greater. A geneticist can advise you better,however. Read more...
Not extra risk. Keep up surveillance like everybody else, and good luck. Read more...

I'm 22 y/o my dad died from pancreatic cancer @ 65 (i was 19) my mom died from colon cancer @ 55 (i was 20). Should I be worried abt me?

Hereditary sometimes. Pancreatic cancer runs in some families. Relatives of patients with pancreas cancer have an increased risk for developing pancreas cancer themselves. Colon cancer is known to run in families. Can consult physician (geneticist) for counseling as far as testing for possible genetic marker and frequency of colonoscopy for early detection of colon cancer. Read more...
A few things. I am very sorry to hear about your loss and your fathers health. In terms of risks, you should be aware that you need to have your colonoscopy 10 years before your mom was diagnosed (assuming it was 55 then yours would be at 45) --unless you have a change in bowel habits, or if you have rectal bleeding etc. Read more...

If my great aunt had colon cancer at 66, lived to 95 and my grandmother had pancreatic cancer at 72, does this sound like Lynch syndrome?

No. You've asked before, right? I'm not sure why you're concerned, but I also honor folks' intuition. It's an easy if perhaps slightly pricey genetic test. If you have decided what you'd do different once you have your answer, ask your physician about it. Read more...

If pain and weight loss were as a result of pancreatic cancer would CT colonoscopy see the tumour on pancreas as it sees these organs as well as colon?

Possible. It sounds as if you previously had a ct scan of your colon? It is unlikely your pancreas was imaged with the "colonography". An abdominal scan or ct dedicated to the pancreas is one of the better imaging studies to properly evaluate your pancreas. Read more...

Is stage 2 pancreatic cancer in one person any more serious than stage 2 breast cancer in another person?

Completely different. Hello, Pancreatic cancer and breast cancer are 2 completely different disease. Stage for stage, breast cancer usually has a better prognosis than pancreatic cancer.
