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

Bronchoscope Dr said No cancer this am so what could it be if Hiler mass & Mediastinal Lymphadenopathy in lung?Tissue sent out after pathologist check

A few possibilities: Several things other than cancer can cause such abnormalities. Various infections and sarcoidosis come to mind. There's no way for a forum doctor to say anything more. The doctor(s) treating you or who did the bronchoscopy are the best to ask. ...Read more

What's the difference between lung cancer and emphysema?

What's the difference between lung cancer and emphysema?

COPD versus cancer: In emphysema the air sacs of the lung (alveoli) are damaged. The result is the lung "traps air in the damaged sacs and it becomes hard to exhale. The lung becomes over inflated. Breathing (getting oxygen in and carbon dioxide out) are progressively harder. In lung cancer a cell is damaged and can not regulate its growth, ( ie becomes cancerous) with tumor formation. Both are linked to smoking. ...Read more

What is the difference between emphysema and lung cancer?

What is the difference between emphysema and lung cancer?

Different things: Emphysema is destruction of lung tissue from (most often) smoking. Lung cancer is an abnormal growth of lung tissue that can cause destruction of many tissues, not just lung. They are completely different diseases. But, because the most common cause of lung cancer is smoking, many times patients with lung cancer have emphysema and vice versa. ...Read more

What is the difference between the stage and the grade of lung cancer?

What is the difference between the stage and the grade of lung cancer?

A lot: Stage refers to extent of cancer: generally stage 1 & 2 are early cancers; stage 3 involves spread to the nodes or structures in the middle of the chest; stage 4 involves spread to both lungs or other organs. Grade refers to the degree of abnormal appearance of the cancer when seen under the microscope- usually grades range from 1-3. ...Read more

What's the difference between small cell and non-small cell lung cancer?

What's the difference between small cell and non-small cell lung cancer?

Everything: Small cell lung cancer is almost completely different than non small cell- the only thing the same is that it is located on the lung and may give the same symptoms. They are different in molecular biology level, they look and behave differently. Small cell behaves more agressive- like systemic disease even from the first presentation; have different treatment and prognosis .D/w your oncologist. ...Read more

What's the difference between non-small cell lung cancer and small-cell?

What's the difference between non-small cell lung cancer and small-cell?

Entirely different: Different types of cancer. Small cell multiplies fast and is considered spread at the time of diagnosis. Because of that, it may also respond better to chemotherapy. Non-small-cell grows more slowly and if found in an early stage, may be curative by surgery. ...Read more

What is the difference between stage 3a and stage 3b of lung cancer in terms of tnm?

What is the difference between stage 3a and stage 3b of lung cancer in terms of tnm?

3b is more advanced: Although both stages are serious, stage 3b tends to have more severe lymph node spread, usually meaning spread out side the affected side of the chest to the collar bone, neck or lymph nodes in the opposite chest. The 5 year survival with 3a is 20-25%, with 3b is 10%. ...Read more

What is the difference between small cell lung cancer and non-small cell lung cancer?

What is the difference between small cell lung cancer and non-small cell lung cancer?

Different cell types: lsmall cell cancer of the ung is a neuroendocrine tumor responding to chemo such as the adriamycins (doxorubicin). Non small cell cancer represents the adenocarcinomas and squamous cell cancers requiring a different groujp of drugs that usually include the platinums and the newer monoclonal antibodies. ...Read more

Whats the difference between lung cancer and a TMJ disorder and how can I be absolutely sure I have either of these things?

Whats the difference between lung cancer and a TMJ disorder and how can I be absolutely sure I have either of these things?

Not related: Lung cancer usually presents with new onset coughing or coughing up blood. A chest x-ray or ct may show a mass in the lung or lymph nodes in the chest. Diagnosis requires a biopsy, often via a bronchoscope (look into bronchial tubes) or with a ct guided biopsy. Tmj is a dysfunction of the temporomandibular joint and can cause pain on opening or closing the mouth-no association with lung cancer. ...Read more

Doctors, what is the difference between advanced testicular cancer and another advance cancer such as advanced lung cancer?

Doctors, what is the difference between advanced testicular cancer and another advance cancer such as advanced lung cancer?

More curable: Advanced testicular cancer spreads to nodal area. In most instances the primmary is resectable and nodes can most oftern be removed. These tumors are sensitive to radiation and chemotherapy with a high cure rate. Lung cancer when advanced is most often not resectable and invades major pulmonary vessels into pericardium. Effective radiation hard to deliver and chemo limited. ...Read more

What are the differences between breast cancer and lung cancer?

What are the differences between breast cancer and lung cancer?

Breast & Lung Cancer: Breast Cancer and Lung Cancer arise from different parts of the body. Breast cancer almost always arises from the ducts of the breast. Lung cancer usually arises from the lining of the lung. The two cancer have different natural histories. Breast cancer may metastasize or spread to other part of the body, including the lungs ...Read more

Can you tell me about the difference in small cell lung cancer and non-small cell lung cancer?

Can you tell me about the difference in small cell lung cancer and non-small cell lung cancer?

Treated differently: Non small cell cancer refers to any lung cancer that is not small cell. Small cell lung cancer is a subset of all lung cancer that is typically very responsive to chemotherapy, so it is important to know the type of lung cancer to determine the best treatment. ...Read more

What is the difference in treatment between chronic lung disease and lung cancer?

What is the difference in treatment between chronic lung disease and lung cancer?

Different: Non small cell lung cancer mainstay of therapy is surgical resection for appropiate lesions. 5yr survival for stage i nsclc after surgical resection is about 70%, stage ii about 30%. Chronic lung disease is emphysema, bronchitis, asthma, obviously a totally different diagnosis. Patients may develop lung cancer with or without chronic lung disease but more common in smokers. ...Read more

Can any doc tell me what's the difference in small cell lung cancer and non-small cell lung cancer?

Can any doc tell me what's the difference in small cell lung cancer and non-small cell lung cancer?

Cells and treatment.: The cell types and treatment is the biggest issues. Non small cell are adeno, large and squamous cell types. Each have an association with smoking but not always. Treatment is the same. First if possible resection +/- chemo/radiation. Cure can be resection. Small cell=smoking. Can be limitted or extensive. Responds well to chemo. Grows faster, mostly treatable not cureable. Need to talk to ur md! ...Read more

Why would a MRI be better at finding mesothelioma and a ct scan better at lung cancer or is there no difference for the 2?

Why would a MRI be better at finding mesothelioma and a ct scan better at lung cancer or is there no difference for the 2?

There are distinct T: CT scan shows the lungs much better whereas MRI shows the pleural surface much better. Since Mesothelioma starts on the Pleural surface, it is easier to detect it on MRI although CT scan will also pick up most mesotheliomas once they grow to a moderate size. ...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


Tissue (Definition)

The body is composed of tissue that are classically described as beiing derived from three basic embyonic layers known as the endoderm, mesoderm and ectoderm that then differentiate into the structures that compose the body such as skin, soft tissues, bone, muscle, organs, etc. Stem cells are not differentiated and have the potential to ...Read more
