A 45-year-old member asked:

can a high-powered magnetic resonance imaging scanner cause cancer to patients or staff?

No known association: Mri relies on changing nuclear atomic spin, and does not change the chemical bonds of molecules, which can alter dna and cause cancer. However, the use of a contrast agent in patients called gadolinium during the procedure may induce the onset of a debilitating malady commonly known as nsf/nfd. This can cause fibrosing throughout the body. http://www.medscape.com/viewarticle/550783.
Dr. Lawrence Hochman

No: While x-ray based scans do expose the patient to radiation that potentially can cause dna mutations and cancer. Mri does not use radiation, but relies on the nuclear state of atoms. This type of scanning is not known to cause cancer.
Dr. Andrew Turrisi
Radiation Oncology 47 years experience
No: There are no increased rates of cancers, and no experimental evidence that a magnetic field and the pulse sequences used alter dna, as x-rays and ultra-violet light do. The problem with mri's is discomfort in the magnets cause noise, and the cost of the equipment - not cancer causing.

What is the difference in the various stages of colon cancer?

1 doctor answer2 doctors weighed in
Dr. Joseph Roosth
Internal Medicine 35 years experience
Survival, but.....: Used to be, the short answer was simply survival risk with stage 1 having the best prognosis and stage IV the worst. While stages 1/2 still have the highest survival rates but improved surgical techniques and chemotherapy and i'd add lifestyle changes, have leveled the playing field greatly. Colon cancer, even advanced is often quite treatable.

Is provenge (sipuleucel-t) the leading treatment of prostate cancer?

It's only for some: Provenge (sipuleucel-t) is used in a very specific clinical situation with prostate cancer--definitely not indicated for everyone. The best treatment depends on the stage and grade of the cancer.
Dr. William A Biermann
Medical Oncology 46 years experience
It is a complicated and very expensive treatment that has a small benefit for a very small group of patients. Most oncologist nationally use it very infrequently

If i've been using smokeless tobacco for two years, how can I tell if I will get oral cancer?

Dr. James Beck

High risk: Smokeless tobacco greatly increases your chances of oral cancer. If you drink alcohol with it, the risk is even greater. You will inevitably get some form of oral pathology if you continue to use smokeless tobacco. Please stop immediately.
