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 pet scan always diagnose /confirm presence of lung cancer or can only give indication and later biopsy is vital to confirm cancer if a nodule seen?

Can pet scan always diagnose /confirm presence of lung cancer or can only give indication and later biopsy is vital to confirm cancer if a nodule seen?

Bx definitive: A positron emission tomography (pet) scan is an imaging test that uses a radioactive substance called a tracer to look for disease in the body. It is often used to determine the treatment of cancer, if it is spreading, or improving, etc. Used in combination with tests such as ct or mri, it can provide a very high index of suspicion for cancer, but a bx is always definitive and used for tx. ...Read more

Is biopsy the only way of determining the sub-type of Non-Small Cell Lung Cancer? Any non-invasive ways? 1st biopsy inconclusive and risks with repeat

Is biopsy the only way of determining the sub-type of Non-Small Cell Lung Cancer? Any non-invasive ways? 1st biopsy inconclusive and risks with repeat

Need a biopsy: A physician who diagnosed ANY lung cancer without obtaining a biopsy would be committing gross malpractice. You've got SOMETHING in your lung that's VERY worrisome and whatever got it noticed, you should be demanding that the biopsy be repeated anyway and a best diagnosis rendered. Risks? Do you want to die of a missed cancer? I know you don't. Be brave. Best wishes. ...Read more

Can a doctor determine the stage of lung cancer from a lung biopsy?

Can a doctor determine the stage of lung cancer from a lung biopsy?

Lots to staging: Staging of lung cancer identifies t n and m status, or tumor size (t) lymph node involvement (n) and presence of metastasis or distant spread of tumor (m). Staging may include lung biopsy, but may require pet/ct to determine metastasis (m), mediastinoscopy or ebus to asses lymph nodes (n). ...Read more

Why would someone who has had lung cancer surgery need a liver biopsy?

Why would someone who has had lung cancer surgery need a liver biopsy?

Tumor spread: Cancers can spread to different areas in the body. It is not uncommon for lung cancer to spread beyond the lung to other areas such as the liver and bone. If you have a known lung cancer and an abnormality in the liver it may be spread of the lung cancer. Certain tests like an MRI may be helpful to see if it is an often seen benign lesion (hemangioma). If it can't you may need a biopsy. ...Read more

My mom has stage 4 small cell lung cancer in both lungs, in severe pain no biopsy no trtreatment what happens now ? Life expectancy?

My mom has stage 4 small cell lung cancer in  both lungs, in severe pain no biopsy no trtreatment what happens now ? Life expectancy?

One question: Small cell lung cancer is almost always high-stage when it's discovered and the only question is whether she is a candidate for chemotherapy, which can be expected to make the disease vanish for at least several good months. If this is not possible, it should at least be possible to manage her discomfort; ask a hospice physician. ...Read more

My mom has stage 4 lung cancer with no biopsy no chemotherapy or treatment what is her life expectancy?

Its Very Bad cancer: The life expectancy is limited but it depends on where her cancer has spread to. Most patients die due to distant metastases into vital organs. Once cancer has gone outside the lungs, the survival is 6 to 12 months, but can be over one year with rare exceptions. ...Read more

Can you have adeno and squamous lung cancer at the same time? What is the significance for treatment? 2 biopsies --- one from main lung mass showing squamous, one from lymph node showing adeno.

Can you have adeno and squamous lung cancer at the same time?  What is the significance for treatment? 2 biopsies --- one from main lung mass showing squamous, one from lymph node showing adeno.

Yes...: It is possible that there are two different cancers. It may also be that the primary tumor is a combination of the two (adenosquamous) and the biopsy only sampled one part. Adenosquamous tumors contain adenocarcinoma and squamous cell carcinoma. And either or both types of cancer may spread to lymph nodes. ...Read more

What steps are necessary for doctors to diagnose lung cancer?

What steps are necessary for doctors to diagnose lung cancer?

Lung Cancer: Evaluation most commonly includes anatomic imaging (xray, chest CT); tissue sampling (bronch, percutaneous biopsy, surgical resection); and staging (PET/CT, Brain MRI). In addition to this medistinoscopy (surgical eval of medistinal lymph nodes) may be necessary. A team approach between surgeon, medical and radiation oncologists, pathologist, and radiologist should be optimally considered. ...Read more

What's the most relevent test to diagnose non small cell lung cancer?

Bipsy and imaging: The key to diadnosis is the biopsy. This can help determine the subtype which will help guide the course of treatment. Beyond that, the imaging with ct, ct/pet, and MRI will help determine the stage of the cancer. The combination of the stage and the subtype of the cancer will help with treatment decisions as well as prognosis. ...Read more

Which steps are necessary to diagnose lung cancer?

Which steps are necessary to diagnose lung cancer?

First thing: The first step is to find a suspicious nodule or tumor in the lungs, which requires a scan (either xray or ct scan). This can be done for other reasons and find it by accident, done in screening, or done for cough or symptoms. Once a lesion is seen, it needs to be biopsied to confirm it is cancer. ...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

Biopsy (Definition)

Biopsy is tissue removed by needle or cutting to remove part of a body part. It is usually a small amount of material that is processed by a pathologist. Most of the time it is stained and looked at through a microscope to arrive at a diagnosis. Special processes are done for some tissues or problems. The purpose is to tell what the problem is (diagnosis). ...Read more
