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 breast cancer be spotted through a chest CT scan?

Can breast cancer be spotted through a chest CT scan?

Yes and no: A mammogram and ultrasound ate the best way to diagnose a breast mass. However a ct scan may show a obvious large mass or asymmetry in the breast tissue which may lead to a mammogram. A ct scan also may show enlarged lymph nodes which may be a clue. ...Read more

I had bilateral breast cancer and CT with RT. Now CT Scan showed atelectasis or infiltration in the right middle and left lingula. ER doc said it's ok?

I had bilateral breast cancer and CT with RT. Now CT Scan showed atelectasis or infiltration in the right middle and left lingula. ER doc said it's ok?

Atelectasis: There are a number of reasons for atelectasis (collapse alveoli or air sacs) or infiltration (areas of inflammation) in the lung: infection, mucus plugging, or shallow breathing. Though the cause is most likely unrelated to your cancer, lung cancers or recurrent breast may sometimes appear as infiltration. Best thing to do is to schedule a follow-up visit with your oncologist for evaluation. ...Read more

Can a CT scan be wrong in metaststic breast cancer to the lung if the pt is on on chemotherapy and breast cancer was stage 2 grade 3 at diagnosis?

Can a CT  scan be wrong in metaststic breast cancer to the lung if the pt is on on chemotherapy and breast cancer was stage 2 grade 3 at diagnosis?

Read below: Breast cancer can progress or recur in case chemotherapy is not working well against cancer. Ct scan is the best way to look for cancer in the lungs and liver. But it can only show shadows which often require further tests...Either a biopsy or a pet scan if there is any uncertainty about the cause of the shadows. Sometimes radiotherapy can cause shadows on the lungs...So not all shadows are mets. ...Read more

Help please. Could breast cancer show up on a cat scan of the heart or lungs?

Help please. Could breast cancer show up on a cat scan of the heart or lungs?

Maybe: If large enough, it may show up on a ct of the chest, but probably not a ct of the heart (out of the field of view). But mammography is more sensitive than ct at detecting breast cancer. You should have routine screening exams, and a diagnostic mammo asap if you feel a lump. ...Read more

An MRI in nov 2012 showed a radiological cyst on l. Femur; pain since may 2012. I have stage 111c breast cancer. Should i get a pet /ct?

An MRI in nov 2012 showed a radiological cyst on l. Femur; pain since may 2012. I have stage 111c breast cancer. Should i get a pet /ct?

Probably not: On mri, cysts are pretty easily distinguished from metastasis from breast cancer. If you still have concerns, ask your oncologist if he can have the MRI interpreted by a second radiologist to make all are in agreement with the cyst diagnosis. ...Read more

Upper back pain one year. Ct of chest in nov 12 ok. Mri spine ok. Could this be missed breast cancer? I had mammogram sept 12 ok. Not present at rest

Upper back pain one year. Ct of chest in nov 12 ok. Mri spine ok. Could this be missed breast cancer? I had mammogram sept 12 ok. Not present at rest

No, not Realy: Pain in the back with movement is usually linked to posture of the spine or ribs. Cancer at your age is usually found within the breast, and the testing you have undergone already is reassuring. Continue to be medically examined for your concern of cancer, but seek a musculoskeletal physician to help with your chest wall pain. ...Read more

Small short axis mediastinal nodes show on CT I had NHL 5 yrs ago and I am so scared what does this mean. Doc. said scan in 12mths. also 2 4mm lung nodules. Breast Cancer 15yrs ago. I am nuts. He wanted to wait 12 mths. I said NOOOOOOOOOO ?

?

Lets be rational now: Small nodes in the mediastinum( < 1Cm) are not necessarily abnormal, so you can relax and wait to worry. If you had any chest symptoms like pain, fever or cough, then a repeat CT scan or PET scan may be justified . If there are sufficient odds of your lymphoma recurrence being a consideration, repeat imaging studies should be done in 3 to 6 months. Lung nodules of < 5-10 mm are probably benign. ...Read more

Mammogram, ct, MRI and ultrasound tests for breast cancer - what is best?

Mammogram, ct, MRI and ultrasound tests for breast cancer - what is best?

Situational: For screening: mammograms are the most valuable. For diagnosis (palpable mass, mammographic density): ultrasound can be very helpful. Mris are the most sensitive test for breast cancer, but their prohibitive cost makes this unaffordable for large-population screening. It is best used in high-risk patients, those with very dense breast tissue, and for evaluating the extent of a known breast cancer. ...Read more

Could heart MRI detect breast cancer?

Could heart MRI detect breast cancer?

It is: possible, but a cardiac MR is not optimized for breast evaluation, so breast cancer detection on cardiac MR is likely to be accidental and imprecise. It cannot substitute for the standard breast imaging techniques such as mammography, sonography, and breast MR. ...Read more

Is it likely that I have breast cancer if the doctors took a mammogram, then an ultrasound, then a breast mri?

Is it likely that I have breast cancer if the doctors took a mammogram, then an ultrasound, then a breast mri?

Maybe: It is possibe that this could still be benign, it sounds like the docs are checking up on an abnormal mammogram finding. If it was highly suspicious, you would have already have had a biopsy. Hopefully you will get the results soon - get a biopsy if needed, or hopefully, be reassured that it looks ok and have appropriate follow-up scheduled. ...Read more

I have been having twinges in my left breast. Have had mammo, ultrasound & mri. All normal. Breast tissue dense. Concerned about breast cancer. What followup do you recommend? Tests were done last August.

I have been having twinges in my left breast.  Have had mammo, ultrasound & mri.  All normal.  Breast tissue dense.  Concerned about breast cancer.  What followup do you recommend?  Tests were done last August.

Twinges: First it is great news that all of the testing has been normal to this point. I know it is frustrating not having an answer about the cause of the twinges. I would imagine repeating the mammogram in 3-6 months would be reasonable. If there is an early breast cancer (which there doesn't seem to be) you would be catching it early, when it's very treatable. Would need more info about twinges... ...Read more

Why would a breast MRI be recommended when you have breast cancer?

Why would a breast MRI be recommended when you have breast cancer?

Several reasons: A breast MRI gives a more detailed picture of the breasts than mammogram or ultrasound. It is recommended in young women whose breasts are dense and hard to see on mammogram. It is also better for detecting certain types of breast cancer (lobular or inflammatory breast cancer.) the downside is that it finds many "spots" that aren't breast cancer. ...Read more

Will a heart MRI detect breast cancer?

Not likely: The equipment used for cardiac scanning, with ct used more than MRI i believe, is usually focused just on the heart structures. So breast evaluation during a heart scan is not likely and the equipment may not be designed to evaluate the breast tissue either. ...Read more

When is breast MRI recommended for breast cancer screening? Is it for the earlier stage or later stage

For high risk women: Yearlly breast MRI in addition to mammography is recommended for women with a 20-25% risk of breast cancer as determined by a lifetime risk calculator, for women who have the breast cancer gene, who had radiation to the chest for hodgekins disease between 10 & 30 years, sometimes for women who have been treated for breast cancer, and for women with a few rare syndromes. To detect cancer early. ...Read more

Breast Cancer (Definition)

Occurs when glandular cells lining the milk ducts and lobules of the human breast begin to grow in an unregulated manner. Often curable if found early and treated effectively with surgery, hormonal therapy, chemotherapy and targeted therapy, or a combination thereof. Early detection before the malignancy becomes large enough to be felt depends on mammography/sonography and MRI imaging of the breast ...Read more

Computed Tomography (Definition)

Ct uses xrays taken an 360 degrees combined with a computer to see"inside" the body. The table moves as the xray tube and detectors spin around the patient 10 times a second or more! the image shows excellent soft tissue detail, enhanced with injection of intravenous contrast or oral contrast. This way the body is shown in slices, in any plane, usually axially, but ...Read more
