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'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

Is it difficult to travel with lung cancer and emphysema?

Is it difficult to travel with lung cancer and emphysema?

A little bit: Traveling with lung disease can be slightly more complicated. Planning for routine medications, including oxygen takes some advanced planning. Discuss your plans with both your pulmonologist and your travel medicine specialist prior to booking the tickets. If you need oxygen while flying you need to arrange for special canisters or machines. Also plan how to mange a flare up at your destination. ...Read more

Can smoking weed once a week give you lung cancer and/or emphysema?

Data lacking: Since the exact cause of the oncogenic (cancer-causing) effects of tobacco is not entirely clear, and the simple role of a chronic irritant has not been clearly delineated, any opinions are pretty much guess work, and as stated earlier, more data is needed. ...Read more

If someone with emphysema or copd, and then gets lung cancer, how low is the survival rate?

If someone with emphysema or copd, and then gets lung cancer, how low is the survival rate?

Low...: Lung cancer has a low survival rate regardless of whether or not COPD is also present. By the time a person has symptoms, the cancer is already advanced so the best cure rate is when it is found before there are any symptoms. Because of this, the best approach is to stop smoking or never start since the prognosis is terrible once symptoms are present! ...Read more

Angioendema?Can it be caused by ACE inhibitors.Can a ACE test level be decreased in other conditions.Emphysema, lung cancer, cystic fibrosis.Copd ?

ACE Inhibitors: Angiotensin converting enzyme (ace) inhibitors are the leading cause of drug-induced angioedema in the U.S. Because they are widely prescribed. Most common is swelling of the lips, tongue, or face, although episodic abdominal pain due to intestinal angioedema may occur. Urticaria and itching are notably absent. The rest of the question is too complex to address here. Thanks. ...Read more

I had a mcrp Mri and it  showed non specific atelectasis bilateral lung bases.  Could this be lung cancer or copd?

Not cancer: Atelectasis is not cancer. It is essentially a sign that some areas of your lungs are not getting as much air due to either blockage or restriction of some reason. This can be seen with foreign objects in airways, scarring, infiltration or poor lung airway movement. ...Read more

Can't tell: Sounds like nothing because you have provided no info. Anyways, I suggest you visit your physician if you have a persistent physical problem. We cannot make an accurate diagnosis online. You need a physical exam and maybe some tests. Best to you and for what it's worth, I know how bad allergies are in TX so I hope it's nothing more serious than that. ...Read more

My husband has severe COPD and lung cancer. He is now getting delirium and body twitches. His mind is not there most of the time. What's this?

Possibilities...: When the lungs aren't able to work properly, the brain doesn't always get enough oxygen and low oxygen to the brain can cause what you describe. In addition, the carbon dioxide cannot be exhaled properly and high carbon dioxide can cause symptoms like you describe. Supplemental oxygen can help with the low oxygen and BiPAP can sometimes help the carbon dioxide level from getting too high. ...Read more

Hello...I'm 42 with under active thyroid and just been told iv got copd..im worried as cancer runs through my family I lost my mum to lung cancer 2yr?

After smoking cessation its relatively easier to control COPD and your risk of Lung Cancer development keeps going down each year after. Make sure you truly have COPD by getting Pulmonary Funtion Test which is essential to make diagnosis. ...Read more

I may have cystic fibrosis, COPD or lung cancer (my maternal grandfather had stage IV lung cancer), how to know?

Diagnosis....: There are diagnostic tests your doctor can order to be sure you don't have these conditions. For example, pulmonary function testing will show chronic obstruction if you have COPD and a chest CT can help rule out lung cancer and there is specific testing for cystic fibrosis. If you are smoking, you need to quit ASAP to lower the risk of COPD and lung CA. See a lung doctor for the testing you need ...Read more

Will radiation therapy for lung cancer make my father's COPD worse?

Will radiation therapy for lung cancer make my father's COPD worse?

Possibly.: Radiation can injure the lung tissue. Therefore since COPD is already an injury they can be additive. The radiation doctor needs to know values for fvc and fev1 (tell you how good the lung is) and consider these in his planning for the radiation. The majority of lung cancer is in smokers and most have copd. So its just how bad it is and how much lung is going to be radiated. ...Read more

Positive for blood in stool. Dr. Won't do colonoscopy because i'm not a candidate for surgery. (have stage 3b lung cancer & severe copd)  any suggesti?

Possibly repeat test: Occult testing often leads to false positives. Abnormal test results may occur after eating meat, a nosebleed or gum bleed. It does not necessarily indicate internal bleeding. With stage iiib lung cancer and severe copd, i suspect your doctor believes there is really no benefit to further testing due to these very severe illnesses that will probably limit lifespan. ...Read more

Copd (Definition)

COPD may include chronic bronchitis, emphysema, or both. Chronic bronchitis is the production of increased mucus caused by inflammation. Bronchitis is considered chronic if you cough and produce excess mucus most days for three months in a year, two years in a row. Emphysema is a disease that damages the air sacs and/or the smallest breathing tubes in the lungs. ...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
