Cancer (Definition)

Cancer is a group of diseases that is characterized by uncontrolled cell growth leading to invasion of surrounding tissues that spread to other parts of the body. Cancer can begin anywhere in the body and is usually related to one or more genetic mutations that allow normal cells to become malignant by interfering with internal cellular control mechanisms, such as programmed cell death or by preventing ...Read more

Can you see lung cancer in a chest x-ray?

Can you see lung cancer in a chest x-ray?

Maybe: It depends on the size and location of the lung cancer.

Small cancers (less than 1 cm) may be difficult to identify with chest radiographs.

Ct scan of the chest is much more sensitive in evaluating for lung cancer and associated disease. ...Read more

Small cell lung cancer. How long was it there when you can see it on x-ray?

Small cell lung cancer. How long was it there when you can see it on x-ray?

Weeks to months: There is no hard and fast rule. In studies that tried to detect lung cancer early using a chest x-ray, almost half of the cancers appeared within a year of a normal x-ray. Taking into account the rate of growth of a cancer cell, and the minimum size needed for detection on x-ray, a good estimate for small cell is a few weeks to a few months. ...Read more

What does lung cancer look like on an x-ray?

What does lung cancer look like on an x-ray?

It varies: It can be a mass, or unusual calcifications, or an unusual "infiltrate" on a chest x-ray. In other words, it can have many different appearances. A chest x-ray is a great tool, but it takes skill to interpret. I do not recommend you try to interpret your films, but your doc can review it with you to give insights.

Hope this helps. ...Read more

Does a sternum X-ray rule out lung cancer?

Does a sternum X-ray rule out lung cancer?

No: This x-ray is too limited. We have proven a ct of the chest is very helpful in screening for hi risk people though you don't fit age (55 to 74 who smoked > pack of cig/day for >30 ys and who are still smoking or who <15 yrs ago). Smoking volume history, infections and other factors should be considered before scans. With suspicion your primary md may still start with a chest xray before ct. ...Read more

If one had lung cancer symptoms. Would it show on an X-ray and bloods.?

If one had lung cancer symptoms. Would it show on an X-ray and bloods.?

It might--or not: Advanced lung cancer would show on x-ray. Earlier cancers are better seen with ct scans. If you have been a heavy smoker for 15 or more years, your risk is certainly much higher of a cancer than a non-smoker. Non-smoking related cancers occur, but usually in much older individuals. ...Read more

If I have chest pain and my X-ray was clear do I need to worry about lung cancer why would a tumor not show?

If I have chest pain and my X-ray was clear do I need to worry about lung cancer why would a tumor not show?

Many causes of Pain: Pain in the chest can be caused by many different reasons. Lung cancer can be one of these but it will often produce other symptoms such as cough and shortness of breath. If a chest X-ray is normal then you are not likely to have any tumor in your lungs. Other reasons to exclude is Angina (although it is a disease of the older people) or muscular pain (this is the most likely reason). Such pains go ...Read more

If your having chest pain and worried about lung cancer wouldn't the tumor be big enough to show on a X-ray if having pain?

NO: The size may influence pain; however, the pleura sac around the lungs has multiple nerve endings. Size is not necessarily the issue. ...Read more

If you had lung cancer that has spread to other parts of your body would it probably be big enough to be seen on X-ray or your blood work be off?

If you had lung cancer that has spread to other parts of your body would it probably be big enough to be seen on X-ray or your blood work be off?

Yes and no: When Cancer starts to spread, it begins as clusters of cells that form tiny colonies in other body parts. These will grow in size over a few months to become visible on X-rays and various diagnostic imaging tests such as CT scan and or PET scan. Blood tests do not show cancer cells, so we rely on the above imaging tests and repeat them periodically (every 2-3 months) to monitor for the tumor growt ...Read more

General discomfort in left lung, random sharp pain, had X-ray nothing there but that was 1-2 months ago, I'm 17, don't smoke, worried it's lung cancer?

Cancer unlikely: It is highly unlikely that you have lung cancer.
For good health - Have a diet rich in fresh vegetables, fruits, whole grains, low fat milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco or alcohol in any form. ...Read more

Would a clear chest X-ray mean there is no lung cancer?

Would a clear chest X-ray mean there is no lung cancer?

Not necessarily: Chest xrays are not regarded as good lung cancer screening tools. Ct-scan, while imperfect, is currently the best demonstrated screening tool for lung cancer. A proper protocol chest ct will use about the same radiation as a mammogram.

Lung cancer CAN: Be seen on chest x-ray, depending on the size and location of the lesion. Ct is the gold standard, but much more expensive and has a higher radiation dose. ...Read more

Can a chest X-ray or echo detect lung cancer?

Can a chest X-ray or echo detect lung cancer?

Not easily: Cxr has been compared head to head with chest ct scan for screening in high risk patients for lung cancer. That study, national lung screening trial, found that in high risk patients, screening chest ct scan was more effective, and was found to save lives. Larger cancers might be seen on a cxr, but smaller cancers may be missed. ...Read more

Lung (Definition)

Deoxygenated blood enters the lungs from the right side of the heart and travels to the lungs. When you inspire, oxygen flows into the lungs, transverses the capilliares and attaches to hemoglobin down a gradient. At the same time, co2 diffuses into the capilaries and is expelled with exhalation. Oxygen rich blood then flows to the left side of the heart and into the ...Read more
