- How often should a person get a mammogram?
- For preventative purposes, a mammogram is recommended annually after age 40. However, a doctor may recommend more frequent screenings based on individual risk factors and medical history.
- Is it true that dental implants can be pulled out during an MRI?
- Most modern dental implants are not affected by MRI magnetic fields. However, removable dental appliances must be removed before an MRI, and fixed appliances should be checked for MRI compatibility to avoid potential harm.
- What are the alternatives to mammography, and how effective are they?
- Mammography is the gold standard for breast cancer screening, although it can be painful for some. Alternative methods like MRI and ultrasound can be used as supplemental tools, but they aren't as effective as mammography.
- Is it true that only a CT scan can detect lung cancer, and what is the role of fluoroscopy?
- While it's true that CT scans are more sensitive than fluoroscopy for detecting lung cancer, fluoroscopy can still identify peripheral lung cancer. CT scans are more detailed and help determine the location, size, and stage of the cancer.
- Can a CT scan of the chest detect breast cancer, and how effective is it compared to mammography?
- While a CT scan of the chest might incidentally show abnormalities in the breasts, it's not as sensitive as a mammogram for detecting breast cancer. Findings on a CT scan would require further investigation, such as a mammogram.
