Question 1

Does ct scan show cancer?

Accepted Answer

Not all cancer is visible with a ct scan. There are many variables- size of tumor, location, presence or abscence of IV or oral contrast.

Question 2

Will a ct scan show all cancers? are there any cancers that may not show up on a ct scan?does it cover all risks of any cancer?

Accepted Answer

IF is tumor CT will show the mass but for definite diagnosis they need resection or biopsy ,but in leukemia and lymphoma ct dose not show any think.

Question 3

Question 4

What cancer would show up on ct scan of neck?

Accepted Answer

The neck is an anatomically complicated region with many internal structures.  A ct scan of the neck could show both primary and secondary cancers (tumors that started in the neck and tumors that have spread to the neck from other parts of the body).  One primary neck cancer that might be seen on a neck scan is thyroid cancer.  Lymphoma is another.  Tongue / tonsil / larynx cancers also...

Question 5

If i have a bowl obstruction like cancer would a ct scan with contrast show it? i had a ct done and they tolled me everything looks good?

Accepted Answer

If you had an abdominal ct with contrast that “ looks good”  it’s unlikely that you have any kind of obstruction . I’d need to know more about your medical history to further advise you.

Question 6

I'm 23, male, had ct scan show a lesion of a few millimeters on bladder. no other symptoms. what are the odds this is cancer? what else could this be?

Accepted Answer

I assumed the reason for having CT was blood in urine or bacterial urinary tract infection. So, thus far, you need a direct look at the whole interior of the bladder to make sure this tiny lesion of few mm is a tumor or a false image (this is possible). For a 23-y-o man, a malignant lesion is not highm but still possible; I have seen a low-grade malignant tumor in a man as young as 18 yrs old.

Question 7

When would ct scan cancer effects show up? if i received too much radiation as a result of ct scans, when would the cancer potentially show up? could i get canncer in 10-20 years because of ct scan radiation?

Accepted Answer

First, there is no cutoff radiation dose which is "too much" above which will result in cancer.  The risk of cancer simply starts out low and increases the more radiation you receive. Development of cancer is like rolling dice (do you have good luck or bad luck?) - the more radiation you're exposed to, the more chances you're taking at rolling the dice. Cancer induced by radiation does take many years to develop; the following are some examples:

- the average latent period before cancer develops is about 25 years for cancers of the brain, colon, skin, and lung. 
- the average latent period for breast cancer is 22 years and for cancer of the salivary glands/thyroid glands is 20 years. 
- the average latent period for bone cancer is 10 to 15 years and for leukemia is 7 to 10 years.

However, the time periods described above are averages and cancers can develop more than 50 years after radiation exposure.

Question 8

Ct scan shows thickening of  lower esophagus wall.  is that cancer or what is it.  i am concerned.  thanks?

Accepted Answer

Thickening of the esophageal wall does not necessarily mean cancer but should be ideally checked out by a gastroenterologist who can perform an Endoscopic exam which means examination via a tube with a lighted camera, especially if there are symptoms.

Question 9

Will a ct scan (no contrast) detect cervical cancer if it's stage 2b or above? i realize a ct can't diagnose cervical cancer, i'm just wondering how likely it is that something would show up on a ct.

Accepted Answer

A CT scan is a general diagnostic tool. It is possible to pick up a mass on CT depending on the size and the body of the person. However there is no way to be 100% sure it is a cancer until further testing, usually biopsy, is performed.

Question 10

Does a ct scan that shows dialation in one of the kidneys mean cancer?

Accepted Answer

Dilation is a reflection of obstruction which may be due to a cancer or a benign tumor/polyp, a small stone, or a scarring of ureter.
