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?

In brief: Delayed, high dose

In general, ct scans do not by themselves cause cancer.
You would have to have had dozens upon dozens to risk the development of cancer. Having said that, when radiation induced cancers development, they are usually in the field of radiation, and usually are sarcomas (soft tissue malignancies). Based on your age, you would have to have had hundreds of cts in a short time 15-20 years ago.

In brief: First,

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.
