A CT scan can often detect evidence of a growth or tumor. If cancer is suspected, a biopsy is usually performed to determine whether the growth is malignant or benign. (I know this because my son, currently in remission from cancer, has had multiple CT scans to look for regrowth of his original tumor. I was told that if a regrowth occured, a biopsy would be done.)

Yes it can. It is uncommon, but the radiologist might miss the specific section in which the tumour is; or the tumour could be the same density as the surrounding matter. Also, there are two types of scan, with and without shadowing, and one is better at finding tumours and other insults to the brain matter than the other is; if the specific thing you have is more easily found by the type of scan you're not having, your problem can be missed.

Yes but there are many factors. If it is a new stroke, the CT scan is usually done first to look for bleeding caused by the stroke. (new strokes may not be seen for the first 24 to 48 hours on CT scan but any bleeding from the stroke can be seen immediately) If there is bleeding the hospital will change what they normally do to help minimize the stroke effects. If it is an old stroke, there are other tests the doctor may do to see changes caused by the stroke.

Yes, a cat scan can detect cancer. It cannot detect all cancers all the time.
