Severe vitamin d deficiency. and i've had 3 ct scans. does that mean i have cancer?

No: Vitamin d deficiency and having 3 ct scans does not mean you have cancer. Why were the scans done, and what were the results? You need answers to these questions. If you have severe vitamin d deficiency, the cause needs to be determined. Close follow-up with your health care provider is necessary so you can get answers to these questions.

No: Vitamin d deficiency can be from inadequate exposure to sunlight (plenty of that in la), sunscreen, dark skin, inadequate intake (not many sources: fatty fish, fortified dairy, foods), poor absorption, e.g. Gut problems like celiac disease, crohn's disease, kidney or liver problems. Lots of causes besides cancer, especially in an 18 year old. See if you respond to rx. Got symptoms, get checked...
