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

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 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

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 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 connection between cancer and oxygenation?

What is the connection between cancer and oxygenation?

Be careful: If you hear this, you are probably talking to a charlatan, perhaps a peroxide advocate. Cancers develop a relatively anaerobic internal milieu by natural selection over time and this accounts for some of the real science that these folks use in support of their claims. ...Read more

What is the relationship between cancer and oxygenation?

What is the relationship between cancer and oxygenation?

There are many: It is a very complex interaction and we learn more about these processes all of the time. It depends on which cancer type we are talking about. Malignant cells are alive and active as are all of our cells in our body. They each need oxygen delivered by blood to perform basic metabolism. Chemotherapy and radiation create oxgen radicals inside ca cells to kill them, so o2 is needed to kill them. ...Read more

What is the likelihood of someone getting cancer from smoking?

What is the likelihood of someone getting cancer from smoking?

Depends on many: factors, including the individual's family history and genetic predisposition, how much they smoke, how they smoke it (deep inhalation, holding it longer etc.). A light smoker may only have about a 1% chance of getting cancer in 10 years (1/2 pack or less) while a heavy smoker (2 ppd) may have as much as a 15% chance. In general, about one in 15 smokers will have cancer in their lifetime (6-7%). ...Read more

What are the symptoms of lung cancer compared to emphysema?

What are the symptoms of lung cancer compared to emphysema?

Cough: Emphysema typically causes breathlessness with exertion. Cancer is silent at first, but later can cause persistent cough or even coughing up blood. Chest pain that is persistent may occur. Emphysema generally doesn't cause much coughing, unlike chronic bronchitis which often occurs in combination (copd). ...Read more

What is the symptoms of lung cancer?

None in early stages: Lung cancer may not produce any noticeable symptoms in the early stages. In approximately 40 percent of people diagnosed with lung cancer, the diagnosis is made after the disease has advanced. In one third of those diagnosed, the cancer has reached stage 3. Cough, weight loss, blood in sputum, hoarseness, and shortness of breath are some symptoms. ...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 is the difference between metastasized brain cancer and cancer that began in the brain?

Prognosis/tx differs: Cancers that begin in the brain and cancers that metastasize to the brain from another primary site (e.g., lung, breast, colon, melanoma) have different prognoses and different treatments. ...Read more

Is there a relation between smoking and cervical cancer?

Is there a relation between smoking and cervical cancer?

Yes: Well, probably. It's statistical, and not so intense as for lung or throat cancer. The people who look at this stuff claim that this holds up when you control for other risky behaviors, and it does make some sense biologically. The question is also moot, since cervical cancer is preventable (vaccine, regular pap smears and follow-up for all) and there are plenty of other reasons not to smoke/. ...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
